摘要：

This article presents a compact, enhanced bandwidth, and variable dual band notched printed monopole antenna for ultra wideband (UWB) applications. By inserting a simple inverted L-shaped slot in the ground plane and modifying the lower edge of the patch, wider bandwidth with usable fractional bandwidth of 139.2% (3.1-17.3GHz) is achieved whereas two inverted U-shaped slots in the corner modified patch are embedded to realize two notch bands exactly at WiMAX (3.25-3.75GHz) and WLAN (5.1-5.9GHz). A precise design formula is also proposed to calculate the length of the slots. The proposed simple antenna structure with a 50 feed line has been obtained within a small size of 0.11x0.19. The simulated results are validated using measured results to show potentiality of the proposed antenna structure in UWB applications.
