Dual-Mode Resonator-Based Filters and Filtering Antennas

Speaker: Kirti Dhwaj
Affiliation: Ph.D. Candidate - UCLA

Abstract:  Dual-mode resonators are known to provide a smaller spatial footprint compared to their conventional counterparts. In this presentation, I will show certain applications, which the dual-mode resonators facilitate in an efficient manner.

Section I (Microwave Filters) would focus on deciphering a previously considered exotic filter topology from a dual-mode resonator perspective. The results would then be used to build a four pole planar waveguide filter with integrated microstrip and coplanar waveguide structures.

Section II (Microwave Filtering Antenna) would describe various topologies of filtering antennas implemented through bandpass filter synthesis approach. Several implemented properties like dual-band, duplexing, quasi-elliptic and novel transmission zero responses would be presented.

Section III would describe a small resonant on-chip antenna developed for 550 GHz application. The integration of filtering network in the antenna affords it larger bandwidth and gain – key parameters of sub-mmW antenna development.

Biography: Kirti Dhwaj is a Ph.D. student in the Microwave Electronics Laboratory in the Electrical & Computer Engineering Department at UCLA.  He received his M.S. (Electrical Engineering) degree from UCLA in 2014 and B.Tech (Electronics and Communication Engineering) Degree from the Indian Institute of Information Technology, Allahabad in 2012.

Kirti’s research interest is primarily filter theory and its applications to planar high-frequency circuits.
