New UWB antenna with inverted F and U shape slots to reject WLAN and X-band applications

In this paper, we propose new Ultra Wide-Band (UWB) antenna using inverted F-slot in the patch and U-slot in the microstrip feed line. This antenna is designed to cover the Federal Communication Commission (FCC) bandwidth (BW) for UWB applications (3.1-10.6 GHz) beside it has two notch bands: one at the Wireless Local Area Network (WLAN) applications based on the IEEE 802.11 standard for the frequency band of (5.15-5.825) GHz, and the other is at the X-band uplink and downlink frequency ranges (7.2-8.4) GHz The antenna has a rectangular patch, microstrip feeding line and partial ground plane. The microstrip feed line is designed for 50 Ω input impedance. The characteristics of the designed structure are investigated by using Finite Element Method (FEM) based electromagnetic solver, High Frequency Structural Simulator (HFSS).
