Slotted Ground Miniaturized UWB Antenna Metamaterial Inspired for WLAN and WiMAX Applications

A miniaturized ultrawideband (UWB) microstrip-fed patch antenna on FR4 substrate is proposed. For miniaturization of UWB antenna resonating 3.1-10.6 is designed Ghz using fractal approach of the radiating edge. A miniaturization of active patch area and antenna volume is achieved up to 45.33% and 31.2% respectively. The proposed miniaturized UWB antenna with metamaterial loading and slotted ground structure obtained the WLAN and WiMAX frequency bands. Results are experimentally demonstrated over the UWB operation.
