Description |
In this article, a novel printed ultra-wideband (UWB) antenna with band stop characteristics is proposed. The proposed antenna is a simple U-shaped monopole structure where a rectangular strip is placed on both sides at the top of semi annular ring monopole structure. The band rejection characteristic is achieved by introducing a pair of L-shaped slots in the ground plane to prevent interference due to wireless local area network (WLAN) systems operating within ultra-wideband. To achieve the desired UWB response with WLAN band notched characteristics, the dimensions of rectangular strip, L-shaped slot, symmetrical step slot on the both edge of ground plane, a single slot in the center of the ground plane and the gap between the ground plane and the radiating structure are optimized. Frequency rejection characteristics depend on the dimension of L-shaped slot and can be fine controlled using other parameters. The antenna structure is designed, fabricated and tested. The simulation and measurement results show that the return loss = -10 dB from 3.09 to 10.6 GHz with band stop characteristics in 5.11-6.14 GHz frequency band. The radiation characteristics show its suitability for indoor wireless communication. (C) 2011 Wiley Periodicals, Inc.
