CPW-fed Monopole Printed Antenna using Staircase shaped Defected Ground Structure for Wireless Application

Abstract

A CPW- fed monopole printed antenna using staircase shaped defected ground structure has been proposed in this paper. In this Defected ground contains a wide asymmetrical rectangular slotted ground with additional staircase shaped stub and a pair of inverted L shaped stub on either side of CPW–fed. The proposed antenna results a broad impedance bandwidth of 1.32GHz-3.23GHz(1.91GHz) at 2.1GHz solution frequency, and having a very good radiation pattern, suitable peak gain of 4.42 dB and high impedance matching with VSWR<2,which make it suitable for wireless and WLAN applications as CDMA, GPS, Wifi, Bluetooth, LTE33-41.
