Abstract

The ultra-wideband (UWB) wireless communication has become a hotspot in current researches, which faces new challenges at the same time. One novel ultra-wideband microstrip antenna is proposed, and a U-shaped slot is cut in the radiation patch to obtain the band-notch function, and the results are simulated by using electromagnetic simulation software CST MWS (CST microwave studio). Experimental results show that the VSWR in the frequency band from 3.05 to 13.8 GHz is always less than 2, which covers the band FCC (Federal Communications Commission) proposed. Meanwhile, the antenna achieves relative stability and good omni-directional radiation performance, which meets the request to antenna in ultra-wideband communication very well. The antenna also has a band-notched function in the frequency range of 3.14-4.0GHz and 5.13-5.83 GHz. Thus, the potential interference between ultra-wideband systems, WIMAX and WLAN system can be inhibited.
