چکیده
In this paper, a new reconfigurable frequency microstrip antenna with an ability of two rejecting intruder frequency WLAN and WiMAX bands for UWB applications is presented. In this antenna, a defect ground structure (DGS) and a U-shaped slot which is located on the ground plane have been used to improve bandwidth. Antenna impedance matching has been achieved through creating two symmetric incision on the microstrip feed line the antenna. Also rejecting Intruder frequency bands are omitted by two slots on the radiation patch, and the performance of omitting rejecting frequency bands is controlled by putting two switches on the slots of radiation patch. Simulation results show that the designed antenna is able to cover a frequency band 3.1-10.9 GHz (UWB) and does the performance of omitting rejecting frequency bands in two frequency band 3.3-3.8 GHz (WiMAX) and 5.1-5.9 GHz (WLAN).

Design of A Compact CPW-FED UWB Antenna with WiMAX and WLAN Band-Notched Characteristic Evaluated in AHP Framework
In this article, we present a new design of a coplanar waveguide fed (CPW-fed) ultra-wideband (UWB) antenna with dual band-notched characteristics. Two notched frequency bands are achieved by using two inverted U-shaped stepped impedance resonators. The proposed antenna can operate from 2.82 to 11 GHz (118%), defined by VSWR< 2, except two notched bands around 3.5 GHz (WiMAX) and 5.5 GHz (WLAN)...
