A coaxial feed circular microstrip antenna with central frequency of 7.2 GHz was designed based on the applica?tion of microstrip patch antenna in the wireless fuze. The antenna dielectric substrate′s relative dielectric constant is εr=4.4, its return loss is less than 20 dB and the antenna gain is greater than 5 dB. According to the principle of microstrip antenna, the antenna designed with HFSS software was tested. The results show that the antenna resonant frequency,return loss and other performance parameters can meet the design requirements.
