Abstract
Bandwidth enhancement of a rectangular monopole UWB antenna using M-shaped strip with triple band notched characteristic is presented. Antenna consists of an exciting rectangular patch with two C-shaped and one inverted U-shaped slots along with defected ground plane which is coupled with M shaped strip. By inserting slots to the rectangular patch, three notched frequency bands are achieved. A conceptual modal, which is based on the simulated impedance of the proposed rectangular patch antenna, is also made to investigate the triple band notched characteristics. The simulated impedance bandwidth of antenna defined by VSWR < 2 is 8.80 GHz ranging from 3.35 GHz to 12.15 GHz with triple band notches first at WiMAX (3.53 – 3.98 GHz), second at WLAN (5.16 – 5.80 GHz) and third at ITU-band (7.82 – 9.08GHz).
