Circularly Polarized Microstrip Patch Antenna with FR4 Substrate in Dual Feed for WLAN Applications
Microstrip patch antennas being popular because of light weight, low volume, thin profile configuration which can be made conformal. Wireless communication systems applications circular polarization antenna is placing vital role. In this paper, the authors introduce a new technique to produce circular polarization. Hybrid coupler is directly connected to microstrip antenna to get circular polarization. The dual fed circular polarized microstrip antenna is etched on a FR4 with dielectric substrate of 4.6 with the height of 1.6mm.Simulation is done by ADS software.
