In general, current distributions for different microstrip structures such as Single Microstrip Line (SML), Coupled Microstrip Line (CML) and Microstrip Patch Antenna (MPA) are obtained by using Method of Moments (MoM) in conjuction with closed-form spatial domain Green’s functions. Specifically, MPA is designed to obtain a Wideband Microstrip Patch Antenna (WMPA). The current distribution is acquired by the same analysis and bandwidth is obtained from the return loss graph for this WMPA. Standard MPA and WMPA bandwidths are compared. First, MoM analysis is used to find the current distribution of SML. Then, current distribution on CML is found, in that case by considering the interaction between the lines. Afterward, current distribution on MPA is calculated. Finally, WMPA is obtained by opening two parallel slots on the metal patch of standard MPA. Current distribution on WMPA is found by using matrix deleting method such that there is no need to re-execute software program for this new geometry. Thereafter, bandwidth of WMPA is obtained from the return loss graph. Bandwidth values for standard MPA and WMPA are compared and the increase in bandwidth is observed.M.S. - Master of Scienc
