Abstract :
In this paper, we propose a new Ultra Wide-Band (UWB) antenna with ground-slot. This antenna is designed to have a band notch that separate between the Worldwide Interoperability for Microwave Access (WiMAX) applications based on the IEEE 802.16 standards for the frequency band 3.3-3.8 GHz and the X-band uplink and downlink frequencies 7.25-7.75 GHz and 7.9-8.4 GHz respectively, beside this frequency notch reject the free Wireless Local Area Network (WLAN) applications band that based on the IEEE 802.11 standard for the frequency band of 5.15-5.825 GHz. The ground slot is designed at 5.7GHz to have a wide rejection band 4.2-7.0 GHz. The antenna has a circular patch with co-planner waveguide (CPW) feed with 50 Ω input impedance. The characteristics of the designed structure are investigated using finite element method based electromagnetic solver, HFSS v.11. Promising return loss data with good matching and omni-directional radiation pattern are obtained.
