Design of a Circularly Polarized T – Stub Coupled Microstrip Patch Antenna for WLAN
Keywords:
Active antenna, T – coupled junction, DC Isolation, circular polarization, axial ratioAbstract
In this paper a new way of feeding single layer microstrip patch antenna to generate circular polarization using electromagnetically coupled microstrip T junction is proposed. The proposed antenna eliminates the need for capacitors in the RF path for active antenna applications in wireless local area network (WLAN). The simulated results using IE3D software were verified by measurement using the vector network analyzer.
