Abstract

Antennas has been an essential component of modern microwave and wireless communication systems. Although the antenna research has been around for many years, it still faces some fundamental challenges and has to meet new requirements arisen from novel applications. Furthermore, the antenna research has become a subject of multiple-disciplinary effort which include the study of radio propagation and communication systems, its interaction with human subjects and other biological systems, the performance enhancement using novel materials and accurate numerical characterisation based on multi-scale modelling techniques. In this talk, the classic antenna theory will be reviewed and it will lead to an introduction of some new antenna designs based on applications such as body-centric wireless communications, security imaging systems and radio-over-fibre communication systems.

Recent Progress on the Design of the Magneto-Electric Dipole Antenna

Abstract

With the proliferation of mobile phones, wireless communication technologies have penetrated many aspects of our daily lives, such as social networking, business operations or medical and healthcare applications. In all wireless systems, the antenna plays a vital role in determining the overall system performance. The numerous new applications in the market have spurred strong demands for new high-performance antennas. In particular, design of esthetically pleasing wideband antennas with different radiation patterns, beamwidths and polarizations is challenging and exciting.

Directed dipole antennas are simple in structure but poor in radiation pattern control. Microstrip patch antennas are low in profile but narrow in bandwidth. Although techniques are available to improve their bandwidth, the radiation pattern and gain of patch antennas vary undesirably over the operating band. Recently, a new class of wideband antennas designated as the magneto-electric dipoles was proposed. These antennas were developed based on the complementary antenna concept. The basic structure consists of an electric dipole and a shorted patch antenna. These novel antenna elements have many attractive features, including wide impedance bandwidth, low cross polarization, low backlobe radiation, nearly identical E- and H-plane patterns, stable radiation pattern, and constant antenna gain across the entire frequency band. They can be designed with linear polarization, circular polarization or dual polarization. With simple feed structures, they can also be enhanced to become diversity antennas with pattern and polarization diversities. This new class of antennas represents the state-of-the art in antenna technology for mobile communications. In this talk, the operating principle of this antenna will be discussed and the latest development for different applications will be presented.

Biography of Professor Kwai-Man Luk

 Professor Luk was born and educated in Hong Kong. He received his B.Sc.(Eng.) and Ph.D. degrees in electrical engineering from HKU in 1981 and 1985, respectively. He is currently Director of State Key Laboratory of Millimeter Waves at the City University of Hong Kong. His recent research interests include design of wideband patch antennas, dielectric resonator antennas, microwave and antenna measurements, and millimeter wave technologies. He is the author of 3 books, 9 research book chapters, over 280 journal papers and 210 conference papers. He was awarded four US patents and over 10 PRC patents on the designs of various printed antennas.

Professor Luk is a Fellow of IEEE, IET, CIE, FEA and HKIE. He received the Japan Microwave Prize at the Asia Pacific Microwave Conference held in Chiba in 1994, the Applied Research Excellence Award from CityU in 2001, the Croucher Senior Research Fellowship in 2003, and the Best Paper Award at the International Symposium on Antennas and Propagation held in Taipei in 2008. He is a chief guest editor for the Proceedings of the IEEE and a deputy editor-in-chief of PIERS journals.
