【 摘 要 】

UWB array antenna with the high enhancement of gain is proposed. New additional flat reflector with a distance of 20 mm enhances the proposed antenna gain. UWB antenna performance with reflector is better than UWB antenna without reflector structure. Antenna with reflector recorded wider operating bandwidth; 1.9GHz-10.6GHz with higher gain ranged from 3.5dB until 14.2dB compared with without reflector antenna operated from 2.2GHz to 10.6GHz with lower gain ranges of 1.9dB to 9.8dB. The reflector structure enhanced the antenna gain by 50% where the average gain throughout operating frequency for an antenna with reflector and antenna without a reflector is 10.2dB and 6.8dB respectively.
