Abstract

In the present work the rectangular microstrip antenna is loaded by two rectangular slots so that the bandwidth of rectangular microstrip antenna is improved up to 60.53%. The proposed antenna has frequency band in the frequency range 1.82 GHz to 3.40 GHz. This frequency band is suitable for WLAN/WiMAX and other wireless communication applications. The microstrip antenna suffers from narrow bandwidth hence the present work provide an alternative solution to increase the bandwidth. It exhibits gain of 2.80dBi, directivity of 3.15dBi and antenna efficiency of 92.28% at 1.9GHz resonant frequency. The suggested slot loaded Microstrip antenna is fed by 0.3 mm probe feed. The proposed antenna is simulated by IE3D Zealand simulation software based on method of moments.
