Abstract

A compact dual L slit defected ground structure monopole antenna for WiMAX/ WLAN application has been proposed. In this paper, after the L slit is cut on rectangular patch, dual band is generated. L slit with the inverted L slit is providing more gain and good radiation pattern. This is a low profile antenna and after incorporating DGS, the bandwidth is also enhancing. The size of this compact antenna is 26× 40 ×0.8 mm³. The antenna has the range of frequency (2.3- 2.9GHz)/2.4GHz for lower band of WLAN and (3.7- 5.9GHz)/4.8GHz for WiMAX and higher band of WLAN. The bandwidth of 25% is achieved for lower band WLAN and 45% of bandwidth is achieved for WiMAX with WLAN. The gain achieved (2.3-2.9GHz)/2.4GHz is 5dBi for lower band and (3.7-5.9GHz)/4.8GHz the gain is 2.4dBi for higher band.
