| Abstract: | In this paper, a circular polarization array antenna at W band is designed by analyzing and comparing differentfeeding forms of circular polarization array antenna. According to the theoretical analysis and simulation results, constant amplitudeand in-phase feeding of each unit radiation patch is ideal for the realization of circular polarization array antenna at W band, thebandwidth of VSWR and axial ratio of 2x2 array antenna are 3.5% and 2% when VSWR<2 and axial ratio is below 3dB, respectively.The gain of this antenna is 12.2dB at 94GHz. This antenna has a very broad application prospect in military. |
