Abstract

Recently the need of antennas in the ultra-wideband (UWB) has increased. The UWB frequency range varies from 3.1-10.6GHz .This frequency band also includes WLAN band which ranges from 5.1-5.9GHz. An antenna that is designed for UWB applications should not interfere with this WLAN band. Therefore to avoid the interference, an antenna with a notch-band performance has to be designed. The proposed antenna consists of a stepped square radiating patch and two rod-shaped parasitic structures for generating band-notched function. Generally, the structure of patch and the feeding shapes of the antenna will be changed to obtain a wider bandwidth. In the proposed antenna, a notched ground plane with a single square slot is placed at the bottom to provide a wide usable bandwidth (3-14.5 GHz). The bandwidth of proposed antenna is wider than the bandwidth of the existing antenna. The proposed design is very much simpler and reduces the Design complexity of the antenna design.
