Abstract

Ultra-wideband (UWB) frequency spectrum (3.1 to 10.6 GHz) was released in 2002 by FCC of the United State for unlicensed indoor and hand-held commercial applications. Because of the attractive merits such as high mobility, flexibility, and extremely high data rate, the UWB radio systems have been raising more and more attention from scientists and engineers. In recent years many techniques such as embedded open-circuited stubs, Multilayer LCP, and so forth have been proposed for design the UWB band pass filter. For some practical applications, there is a need to introduce notch band within the UWB pass band to avoid the interference from existing wireless communication systems such as between 5.12 to 5.825 GHz band wireless local area network (WLAN). The design of microstrip circular ring antenna parameters must be recognized. The microstrip circular ring patch antenna is designed for reject the WLAN applications operating at frequencies of 5.15 to 5.825 GHz. CST Studio Suite software is used for simulation and design for a decision. The return loss for the antenna is ≤ -10 dB, gain, the form of radiation, the percentage achieved, and so the antenna.
