Abstract :
A circular polarization corporate feed antenna with dual frequencies of 1.575 GHz and 2.3 GHz is presented in this research. The antenna consists of 2 circular radiating patches with the transmission line are divided into two branches. Two different circular patches are able to produce two different frequencies with circular polarization (CP) capacity. With gain of 4.108 dB and 4.23 dB, return loss of -11.58 dB and -18.34dB, the proposed antenna is fully capable to provide the coverage of GPS and WiMax application in the future.
