In this paper, an air substrate microstrip antenna has been designed, the feeding structure composed of series and parallel network is designed in order to reduce the size of the feeding structure, so it can reduce the loss and improve the gain. The antenna is designed at 2.45GHz, the parameters are optimized using Ansoft HFSS software, the results show that the antenna has good gain and radiation pattern characteristics, and fulfill the needs of the antenna design.
