About this document
Dual-Band Circularly Polarized Antenna by Swatilekha Chowdhury is a document available to read on EtoBox.
This document summarizes a dual-band circularly polarized microstrip antenna designed for satellite communications. The antenna achieves dual-band behavior by inserting a small X-band microstrip patch antenna inside a larger L-band patch, both printed on the same substrate. The patches are fed electromagnetically through perpendicular slots in their ground planes connected to 90° hybrid branch-line couplers on a lower substrate. Measurements show the compact design meets bandwidth and isolation specificatio
