In this study, a design method for a circular polarization patch antenna operating at a frequency 1.5 GHz~1.7 GHz was studied. To obtain the wide bandwidth and high gain, air substrate between patch and ground plane was applied. The impedance bandwidth is improved by adjusting the sizes of patch, the distance between main patch and ground plate, the length of internal slots, the position of feeding point, the length of external stub, etc. The antenna is designed and simulated for an operation in the frequency range of 1.5GHz~1.7GHz band. The results show that antenna characteristics such as return loss, gain, axial ratio, radiation patterns are appropriate for the satellite navigation system.
