Design of an Ultrawideband CPW-Fed Monopole Antenna with a Band-Notch Function

摘要

In this paper, a CPW-fed monopole antenna for ultra wideband (UWB) applications using band-notch characteristics with size of (24x24x1.6 mm3) is presented. The antenna is designed for operation across the entire UWB from 3.1 to 10.6 GHz with band-notch in 5-6 GHz, by inserting an H-shaped slot on the CPW staircase feed line. The proposed antenna has a reflection coefficient below -10 dB through the frequency band. Also, reasonable gain values and good radiation pattern over the same frequency band have been observed. Details of the proposed antenna and experimental results are discussed and parametric study is presented.
