Design and performance analysis of a dual band E-patch microstrip antenna in wireless communication

In this paper, the designing and performance analysis of a reconfigurable double E-shaped microstrip patch antenna is carried out. The antenna is primarily designed for its operation at a particular frequency. However, due to re-configurability obtained by inserting a narrow patch in between the two E patches, the antenna will be seen operating at another frequency as well (dual band). Later, in order to draw significant conclusions; the plots for return loss (S11), voltage standing wave ratio (VSWR) and radiation pattern showing the gain will be obtained and then analyzed. In order to make sure that the antenna is working properly at the above mentioned frequencies; the return loss for the optimized reconfigurable E-shaped patch antenna has to be smaller than -10db at these very frequencies. The antenna shows a lot of promise pertaining to wireless and satellite communication applications.
