A Triple-Frequency Circularly Polarized Microstrip Antenna

摘要

A triple-layer patch circularly polarized microstrip antenna is proposed for triple-frequency operation. It is shown that the antenna resonates at three different frequencies of 1.207GHz, 1.268GHz and 1.561GHz with adequate values of return loss and gain. The antenna is designed and simulated with the application of CST software based on the Finite Integral Method. The simulation results and analyses are presented.
