Microstrip-Fed Monopole Antenna with Dual Notch Bands and Ultra-Wideband Features

This research introduces a compact dual band-notched UWB antenna for wireless applications. It comprises a trapezoid patch with rotated L-shaped slits and an E-shaped slot, a modified/stepped rectangular feedline, and a trapezoid ground plane. The findings reveal that the antenna effectively operates within the 3–13 GHz frequency range, covering the UWB spectrum. Notably, two notched characteristics are achieved at 3.8 GHz and 5.5 GHz to mitigate interference from WLAN and WiMAX. The overall performance and key parameters of the antenna is assessed, confirming its satisfactory frequency response, radiations, efficiency/gain levels. Therefore, it meets the essential requirements for modern UWB systems, offering a reliable solution for wireless communication advancements.
