Title: Polarization-Agile Stub-Loaded Square Patch Antenna Array with Sequential Rotation Feed

Abstract: Polarization-agile antennas, capable of multipath fading mitigation, frequency reuse, etc., are important in wireless communication, and implementing them on patch antennas allows the design to be low-profile, inexpensive, and very versatile. This sequential rotation polarization-agile patch antenna array consisting geometrically simple reconfigurable stub-loaded square patch antennas and a single switching circuit for reconfiguration is centered at 1.575 GHz for navigation applications and uses a total of fourteen PIN diodes. Its design is realized on Rogers RO4003C boards, with more than 7.3 dBic realized gain at its center frequency for both right- and left-handed circular polarizations.

Bio: Hsinju Chen is a PhD student at Heliophysics Research and Applications (HeRA) in the Department of Electrical and Computer Engineering, University of Illinois at Urbana–Champaign. They received the B.S. degree in Electrical Engineering and M.S. degree in Communication Engineering from National Taiwan University in 2017 and 2020, respectively. Her previous works span from polarization-agile patch antenna arrays to electromagnetics and antenna education in university classrooms. At HeRA, she will focus on studying the impact of energetic heavy ions on the magnetosphere dynamics. Apart from research, Hsinju reads, reviews, and blogs about literature in all genres. They also love theatre, writing, and backpacking.
