摘要：
In this paper a compact semicircular monopole antenna is proposed for UWB applications. Generally UWB antenna operates in the frequency range of (3.1-10.6 GHZ). To avoid interference between UWB and existing wireless communication systems, band rejection characteristics are proposed.In this paper the author has come up with two rejection bands one is WLAN (4.94-5.85 GHZ) and other one is International Telecommunication union (ITU) band (8.0-8.55 GHz). In the proposed work the semi-circular monopole patch antenna is excited with micro strip line feeding. To get required notching bands concentric rings are placed on the patch. The antenna design is simulated using CST microwave studio. Some of the important antenna parameters like Return losses, VSWR, Radiation pattern are measured. © 2020 Mattingley Publishing.
