SC1 - Antenna and Propagation for Body-Centric Wireless Communications
Dr Yang Hao, Queen Mary, University of London, UK
Professor Peter Hall, University of Birmingham, UK

Carrick Room 1
09:00 - 13:00

Body-Centric Wireless Networks are seen to be a central component in the 4th generation communication systems. Such networks have distinctive features in comparison to other available wireless networks due to the rapid changes in communication channel behavior on the body during the network operation. This short course raises some important issues regarding antenna design and propagation channel characteristics, radio systems compatibility with such an environment and the effect that the human body has on these networks. Meanwhile, physical dimensions, directivity, mutual coupling and so on in antenna design, are classically constrained by the wavelength of the radiation involved. Combined with complex on-body channel characteristics, extra issues may be raised related to human body presence and movement, such as resonant frequency detuning in narrow band systems, signal dispersion and variable gain in UWB network etc. These topics represent research and design challenges in antenna system for future body-centric wireless networks and also form the premise of this short course.

The main topic/technical areas to be covered by this event:

  • What are Body-Centric Wireless Communications?
  • Electromagnetic Properties and Numerical Modeling of the Human Body
  • On-Body Communication Channels at ISM, UWB and millimeterwave frequencies
  • Wearable and Textile Antennas,
  • Flexible Metamaterials for On-body Applications
  • Antennas and Propagation for Telemedicine and Telecare including implantable devices
  • Future Challenges and Industrial Applications

Anja Skrivervik, Ecole Polytechnique Fédérale de Lausanne, Switzerland
Raj Mittra, Penn State University, USA

Carrick Room 2
09:00 - 13:00

Advent of new wireless devices and sensors have fueled a continuing trend toward the miniaturization of antenna size, and the challenges faced in designing these devices need to be met by innovations in antenna technology. As an example, modern cell phones routinely require antennas covering five bands or more, each band having stringent requirements with respect to bandwidth, efficiency and coupling. The design of such an antenna in a minimal space requires the right blend of high performance design strategies, appropriate simulation tools and adapted optimization schemes.

Recently, systems such as WiMAX, UWB, MIMO and RFID have instigated the development of new techniques for designing small antennas with enhanced performance. This workshop will focus on the design of small antennas for a wide variety of applications, including sensors, RFID and multiband antennas. State-of-the-art design solutions for practical applications will be presented, and practical issues such as integration of small antennas into their environment will be discussed.

Topics will include:

  • Techniques for size reduction
  • Bandwidth enhancement
  • Multiband design
  • Small antenna characterization
  • Optimization techniques
  • The use of metamaterials and EBG’s to enhance their performance

SC4 - Genetic Algorithms (GA) and Particle Swarm Optimization (PSO) in Modern Engineering Electromagnetics
Professor Yahya Rahmat-Samii, University of California, Los Angeles, USA

Harris Room 1
09:00 - 18:00

Antenna designers are constantly challenged with the temptation to search for optimum solutions for complex electromagnetic device designs. The ever increasing advances in computational power have fueled this temptation. The well-known brute force design methodologies are systematically being replaced by the state-of-the-art optimization techniques. The ability of using numerical methods to accurately and efficiently characterizing the relative quality of a particular design has excited the EM engineers to apply stochastic global evolutionary optimizers (EO). EO techniques have been applied with growing applications to the design of electromagnetic systems of increasing complexity. The recent popularity experienced by EO methods is not unique to the field of electromagnetics; in fact, EO techniques have been successfully applied to problems in fields ranging from engineering to economics and artificial intelligence. Among various EO techniques, Genetic Algorithms (GA) and Particle Swarm Optimization (PSO) have attracted considerable attention. These schemes are finding popularity within electromagnetic community as design tools and problem solvers because of their versatility and ability to optimize in complex multimodal search spaces applied to non-differentiable cost functions.

One of the aims of this course is to provide the participant with an up-to-date body of knowledge on the applications of GA and PSO techniques to the synthesis and optimization of electromagnetic systems.

Specifically, this course will focus on:

(a) engineering introduction to Genetic Algorithms by reviewing simple GAs and their standard terminology and operators (populations, parents, children, chromosome, selection, crossover, and mutation)

(b) engineering introduction to Particle Swarm Optimization by reviewing terminology and operators (agent, local best, global best, velocity, real and binary, boundary considerations, etc.)

(c) demonstration of potential applications of GA’s and PSO’s to a variety of electromagnetic engineering designs including microstrip antennas, multi-band and wideband antennas, synthesis of non-planar radar absorbing materials for RCS applications, Luneburg lens antenna design, array antennas, synthesis of reflector and horn antennas, design of electromagnetic bandgap (EBG) structures, etc

(d) assessment of the advantages and the limitations of the techniques including discussions on single and multi objective approaches

SC6 - Dielectric Resonator Antennas, Theory, Design and Applications
Ahmed A. Kishk, The University of Mississippi, USA

Ochil Room 3
09:00 - 13:00

Recently, interest in dielectric resonator antennas has increased because of their attractive features such as small size, high radiation efficiency (98%), wide bandwidth, and high power capability for radar applications and base stations. The dielectric resonator antenna is made from high dielectric constant materials and mounted on a ground plane or on a grounded dielectric substrate of lower permittivity. The short course will start by an overview for the development of the dielectric resonator antennas. The theory of operation will be discussed step by step to provide basic understanding. The discussion is provided in simple forms to satisfy audience of different background levels. Design curves will be provided for the circular disc and hemisphere dielectric resonators. Use of these models with other geometries is discussed.

Different excitation mechanisms are demonstrates such as the probe, slot, image line and waveguides. Applications of dielectric resonators in arrays are provided with discussion on the mutual coupling level and the wide scanning capabilities of the dielectric resonator antenna array. The array bandwidth limit is discussed based on the element size and the spacing between the array elements.

The problems related to the practical implementations are considered. Results of a numerical study pertaining to the effect of an air gap, between the dielectric disc and the ground plane or an air gap surrounding the feed probe, on the input impedance and resonant frequency of a cylindrical DRA operating in the TM01ä mode or HEM11ä mode as a function of dielectric constant will be presented. Some of the numerical results are validated experimentally.

Techniques for broadband applications are discussed. Some of the techniques are based on the material properties and some depends on the DRA shape. Several examples are provided. Some elements would provide a matching bandwidth over 40% with reflection coefficients better than –10dB for 50 Ohms ports. Finally, Techniques for size reduction of the DRA are presented to demonstrate the flexibility of the DRA to satisfy the required small size for some applications. The technique will result in small size and keeping wide bandwidth. The applications of the DRA for spatial power combiners are presented.

Recently, the new deployment of wireless systems such as WLAN, RFID, WiFi, WiMAX, UWB, and MIMO significantly boosted the research and development of small antennas with enhanced performance in both academic and industry communities. There have been many new designs and ideas applied in systems and/or published in a variety of journals and presented at conferences. Many claims showed smaller antennas than previous ones. The smaller designs seem not enough attractive for applications and publications. Some even claimed that they have designed the “world smallest” antennas in news.

This course aims to lecture the fundamentals of small antennas and share latest development of miniaturization technologies for small antenna design in modern wireless systems in an engineering point of view. The course will start with the fundamental issues related to small antennas, such as categorization and physical limitations. Then, the important technologies of miniaturizing antennas will be reviewed with physical explanations. The important part is to update the state-of-the-art technologies for the new applications with case studies such as antennas for portable devices in modern wireless communications, such as UWB, WLAN, WiFi, GSM, RFID, MIMO, and so on. One of new ground-independence technologies will be addressed and elaborated. Last, the comments on some claims of “new and smallest” designs with engineering perspectives are provided for open discussion.

This course is designed for both junior and senior antenna researchers and engineers with fundamental materials in design of miniaturized antennas and key issues related to philosophy of small antenna design.

SC12 - Reverberation Chamber for Characterizing Antennas and Mobile Terminals under Rayleigh Fading: Efficiency, TRP, TIS, AFS, Diversity, MIMO, UWB.
Professor Per-Simon Kildal, Chalmers University of Technology, Sweden

Ochil Room 1
09:00 - 13:00
14:00 - 18:00: Free access to succeeding workshop for reverberation chamber users

The reverberation chamber has for many years found application in the EMC area. The last seven years we have shown that it with great advantage can be used also for antenna measurements as it emulates effectively an isotropic multi-path propagation environment. The course will give the basic theory of reverberation chambers, and show how the chamber can be used to measure radiation efficiency, free space radiation impedance, and diversity gain of antennas; total radiated power and receiver sensitivity of mobile phones and other wireless or mobile terminals (GSM, CDMA, DECT, Bluetooth, UMTS); and channel capacity of MIMO antenna systems. The chamber is the only known equipment for direct measurement of diversity gain and channel capacity; the alternative being to drive measurement instruments around in an actual urban environment. A major advantage with this new measurement method is that the measurements fast and easily can be performed when the antenna or phone is located in different talk positions relative to a head phantom or other environments. Special emphasis will be directed towards fast and accurate measurements of static and dynamic receiver sensitivities, known as Total Isotropic Sensitivity (TIS) and Average Fading Sensitivity (AFS), respectively. Reverberation chambers for EMC applications are normally very large, but we will show that for measurements at 900 MHz and above it is possible to use a small chamber that can pass through an 80 cm wide door.

The course is based on recent both published and unpublished material related to extensive measurements in both large and small reverberation chambers.

The reverberation chambers with antenna measurement procedures have been commercialized by the company Bluetest AB (www.bluetest.se).
