Design and analysis of a compact CPW-fed triple band notched printed monopole antenna for UWB application

摘要

This paper presents the design of a compact planar monopole antenna with triple band notched characteristics. The inverted U type slot in the patch results in rejection band centered at 5.5 GHz. A hairpin slot in the feed line leads to good suppression at 6.8 GHz and rejection band centered at 8.1 GHz is obtained by etching out incomplete inverted C type slots. The peak gain obtained is 4.3 dBi. The group delay shows a flat response lying within 1ns except at the notch frequencies.
