Abstract: The design of a new kind of broad-band and wide-angle circularly polarized(CP)mierostrip antennas is presented．Based upon the proximity coupling balance-feed by utilizing the capacitive probe，the 2 V standing wave ratio and wide-angle 3 dB axial ratio(AR)are achieved．With the software of CST，the structure parameters of the antenna are optimized．The simulation results show that the antenna meets the requirements for application．
