Abstract

This paper presents the design and results of a compact Ultra-wideband (UWB) monopole antenna with a dual band-notched characteristic. The antenna consists of a semi-elliptical radiator with two meandered slots on it to produce a deep notch at 3.5 GHz (the center of WiMax band) and another notch at 5.25 GHz (the center of the lower WLAN band). The antenna is fabricated and measured, and the measured impedance bandwidth defined by VSWR<2 is 8.5 GHz (2.5--11 GHz), with the dual notched bands of 3.3--3.7 GHz and 5.12--5.37 GHz are obtained. The computer simulation results of the radiation pattern and peak gain of the antenna also agree well with measurements.
