摘要：
In this paper, a compact triple band-notched ultra-wideband (UWB) printed monopole antenna is proposed with enhanced bandwidth. It exhibits a stable omnidirectional radiation pattern and a dipole-like pattern in the H-plane and E-plane, respectively, for the entire UWB. The antenna consists of a rectangular patch with two bevels. To realize notch characteristics in WiMax (3.3-3.7 GHz) and WLAN (5.15-5.85 GHz) band, two round shaped slots of half wavelength are inserted in radiating patch. The rectangular ground plane has two bevels in upper edge to enhance bandwidth which cover the frequency range from 3 to 15 GHz. The two bevels also help in getting impedance matching especially beyond 10.6 GHz. A pair of C-shaped slots is etched in ground plane to get a third notch in X-band satellite communication band (7.1-7.76 GHz). The effects of each individual slot on band notch characteristics are also investigated. The proposed antenna exhibits stable gain throughout the UWB and it also has a very good capability to suppress gain at notched band. Moreover, the designed antenna has a compact size of 31 mm x 22 mm. (C) 2014 Elsevier GmbH. All rights reserved.
