Abstract
An UWB semi-circular-shaped monopole antenna with double band-notching is presented. The suggested antenna is designed to have two notched-bands to avoid the undesirable interferences with the 3.5 GHz band for WiMAX system and the 5.5 GHz band for WLAN system with a simple structure. The first notch is realized by etching an arc slot in the arc patch. Whereas the other notch is achieved by adding a T-shaped stub on the feeding line. The suggested antenna has a small size of 30 × 25 mm2. The proposed antenna achieves UWB conditions. It operates within a wide band from 2.7 to above 18 GHz with two rejected bands at 3.5GHz and 5.5GHz. The performance of the suggested dual band-notched UWB antenna has been investigated using the CST Software Package. An equivalent circuit of the proposed antenna was realized and investigated. The lumped elements employed in the equivalent circuit modeling of the suggested monopole antenna were determined using the Advanced Design System (ADS) software.
