A DOUBLE-PRINTED TRAPEZOIDAL PATCH DIPOLE ANTENNA FOR UWB APPLICATIONS WITH BAND-NOTCHED CHARACTERISTIC

Abstract

In this paper, a novel double-printed trapezoidal patch dipole antenna suitable for UWB applications with band-notched characteristic is presented and investigated. The band-notched characteristic is achieved by inserting T-shape slots on the trapezoidal radiating patches. The impedance characteristic, radiation patterns and the transfer function are studied. Experimental results show that the proposed antenna covers the entire UWB band (3.1{10.6GHz) while it has a notched band for the IEEE 802.11a frequency band (5.15{5.825GHz). Measured group delay, transmission characteristics and Time domain characteristics indicate that the proposed antenna satisfles the requirement of the current wireless communications systems.
