Improved performance of UWB antenna by substrate perforation and slit notch

In this paper a compact semi elliptical monopole ultra-wideband (UWB) antenna has been presented. A new technique to improve the performance of the antenna by perforation of the substrate with two circular holes was used. This perforation has significant effect to minimize the return loss in additio...
