Composite shorted patch designed for improved radiation patterns

Published in Institute of Electrical and Electronics Engineers Inc.
In this paper, a wideband shorted differentially fed patch antenna has been explored based on the composite aperture concept. Two λg/4-folded S-band patches are placed on a compact ground plane which promises 200° wide symmetrical radiation patterns over the principal planes along with 50% operating bandwidth. 7 dBi peak gain has been recorded with more than 45 dB co-to-cross-polarized isolation spanning over 360° angular range. © 2019 IEEE.
