Abstract

A broadband circularly polarized microstrip antenna array is presented in this paper. This array has 8X8 elements and a parallel feed networks. The whole size of this X band array is 190mm X 190mm X 0.787mm. The measurement of the bandwidth of this array is 7.32% (VSWR<2), the gain is about 24dB and the axial ratio is less than 3dB in the operating band. This single layer microstrip antenna array is promising in application because of its compact size and excellent characteristics.
