Bandwidth-expanded U-slot patch antenna with shorting wall

Microwave U-slot patch antenna with shorting wall is suitable for ultra wideband (UWB) communication system on ceiling and aerocraft. This article introduces the simulation and the experiment of the UWB antenna model which increase its impedance bandwidth and gain bandwidth. The antenna bandwidth is expanded by the diversification designed for the feed pin. The simulation model and the test result are also presented and the results are found in well agreement. The impedance bandwidth of the antenna is compared with reference [1]. The research has made big advancement in expanding antenna bandwidth.
