A Simple UWB Antenna Design with WiMAX/WLAN/X Triple Band Rejection Features

Abstract

A rectangular triple band notched ultra wideband (UWB) antenna is suggested in this study. At the IEEE.802.16 WiMAX band 3.3-3.7 GHz, IEEE 802.11a WLAN band 5.1-5.85 GHz, and X band satellite downlink 7.1-7.9 GHz frequencies, etching slots in the radiating patch accomplishes band rejection. The antenna principally acquired UWB features by seceding the ground framework in a staircase shape, as well as triple-band notch characteristics by inserting three slots on the radiating patch and varying slot length in an exponential manner. Furthermore, the suggested antenna has obtained a minimum return loss of -32 dB and a maximum return loss of close to-1 dB across the UWB, as well as band notch
