Circularly Polarized T-Stub Coupled Microstrip Antenna Structure for WLAN

Abstract

In this chapter, a novel feeding mechanism for single layer microstrip patch antenna to generate circular polarization using electromagnetically coupled microstrip T junction is presented. The antenna structure eliminates the need for capacitors in the RF path for active antenna applications in wireless local area network (WLAN). The simulated results were veriied by measurement using the vector network analyzer.
