| Abstract: | A single-element circularly polarized microstrip patch antenna was analyzed based on the cavity-mode theory.By studying the design method of the circular polarized microstrip array antenna,a 64 element circularly polarized microstrip array antenna with sum-difference network which worked at 35.75GHz was designed.It was simulated and optimized by the HFSS.Experiment result shows that the antenna provides the gain of 21dB and good axial ratio.The different beam has a zero depth better than 20dB. |
