Abstract

This paper presents a design of dual band-notched monopole antenna for ultra-wideband applications. The antenna consists of a disc-like radiator and is fed by a microstrip line. By using C- shaped slot and hairpin slot, the dual rejected band characteristics are successfully obtained. A practical example for a UWB antenna (from 2.90 to 12 GHz) is demonstrated, with two notched frequency bands at 3.5 GHz and other at 5.5 GHz. Simulation and measurement results show that the antenna impedance bandwidth covers the frequency range of 3.1 to 10.6 GHz, which meets the requirements of UWB application well. Moreover, the proposed antenna has almost omnidirectional radiation pattern.
