The objective of the proposed research program is to investigate and design innovative advanced antennas to achieve a high gain, reconfigurable radiation pattern capability and multi-band operation for future generations of wireless communications at millimeter-wave bands. This research program focuses on tree inter-related projects: millimeter-wave dielectric resonator antennas, electromagnetic band gap (EBG) materials and their applications in the design of agile EBG antennas with multi-band operation, and beamforming antenna array systems. (i) I will pursue the theoretical and experimental studies of high-gain and broadband dielectric resonator antennas operating in millimeter-wave bands, this topic includes antenna design, modeling and development using new dielectric materials and new architectures, ii) I will continue to investigate agile antennas with reconfigurable radiation pattern using new materials such as EBG structures or metamaterials, and we also expect to extend this concept to dual- and multi- band agile EBG antennas in order to simultaneously serve different systems at different frequency bands, and (iii) I also propose to perform theoretical and experimental investigations for developing new beamforming antenna array systems for wireless applications at millimeter-wave bands. In this research program, I intend to capitalize on my previously successful work and continue to excel in designing new advanced antennas for millimeter-wave wireless applications.
