A novel ultra-wideband microstrip antenna

This paper describes the design of a novel ultra-wideband (UWB) antenna for UWB applications. The design is based on planar rectangular monopole microstrip antenna. The optimum antenna geometry is obtained by computation calculation, and the results were simulated by using electromagnetic simulation software CST MWS(CST microwave studio). The results show that the microstrip antenna can get in the range of 2.9~11.3 GHz. This antenna has a good radiation characteristic, and basically has satisfied the ultra-wide band request to the antennas.
