摘要
In this paper, a novel printed circinal slot antenna with band-stop function suitable for UWB application is presented and investigated. This kind of antenna is designed to be used in frequency band of 3.1-10.6 GHz. Band-stop characteristic of antenna to reject the frequency band of 5.15-5.825 GHz, which is limited by IEEE 802.11a, is realized by slotting on the ground. Experimental results show that the proposed antenna meets the requirement of wide-working bandwidth of 2.3-12 GHz with VSWR < 2, while avoiding the interference with the 5 GHz WLAN band. The parametric studies are performed numerically, and transfer functions of the antenna systems are given experimentally in this article.
