Abstract
This work presents analysis and design of a low-profile quadruple band rejection UWB circular monopole. The band reject features can be obtained by using EBG structures as well as etching an inverted C shape slot in the radiating patch. The band rejection characteristics of an antenna operating in UWB are necessary to avoid interference with narrow bands having frequencies such as (2.43 – 2.65) GHz – Bluetooth, (3.2 – 4.1) GHz – WiMAX, (5.1 – 5.9) – WLAN, (6.6 – 7.4, 7.4 – 8.2) GHz – WPAN and X-Band satellite communication (both Uplink & Downlink). The proposed antenna comprises to have compact dimensions of about 46 x 26 x 1.6 mm3 with a volume of 1913.6 mm3. The simulations are carried out by using HFSS. The designed antenna is fabricated and the corresponding results are Measured and validated. It is found that both the results are significantly matched.
