摘要

An effective design method is proposed to develop an excellent performed quad-band filtering UWB antenna. A spiral-shaped stub (SSS), two T-shaped stubs (TSSs) and an arc-shaped slot (ASS) are utilized to realize the proposed quad-band filtering characteristics. The independently tunable band-notched characteristics are carried out by adjusting the dimensions of SSS, TSS and ASS respectively. The proposed quad-band filtering UWB antenna is fabricated and measured for validation. The simulated and measured results show that this antenna can provide a wide bandwidth covering 3.1-10.6 GHz with four band notched characteristics and omnidirectional radiation patterns in its H-plane, which render it suitable for indoor UWB communication applications.
