Design a multi-band circularly polarized microstrip antenna for ISM (2.4GHz, 5.8GHz) and WiMAX (3.3GHz-3.6GHz).Using Ansoft HFSS15.0 for the simulation analysis, The size of the resonance point and the resonance bandwidth are adjusted by opening four triangular grooves on four sides of the radiation patch. The simulation results show that the frequency band of the antenna’s return loss below -10dB is 2.38GHz-2.52GHz,3.37GHz-3.45GHz, and 5.6GHz-5.9GHz. The antenna meets the design requirements of multi-frequency and miniaturization.
