Abstract
In this article, a simple, low cost, and compact-printed monopole ultrawideband (UWB) antenna with band-notch characteristics is proposed. The antenna operates from 3 to 11.2 GHz covering the UWB band (3.1-10.6 GHz), while rejecting the frequency band 5.15-5.825 GHz, which is limited by IEEE 802.11a. The proposed antenna has a small size of 26 x 31 mm(2) and is designed on an FR4 substrate with permittivity (epsilon(r)) 4.5 having a thickness of 1.52 mm. A parametric study is performed to understand the effects of antenna parameters on its performance. A good agreement between simulated and measured results is also observed.
