Abstract
The proposed design is implanted on the radiating patch of microstrip antenna, which leads to wider bandwidth while keeping the size small and it is an improvement from previous research of single branch like slot. It presents the design and simulation of rectangular microstrip patch antenna with a pair of branch like slots for wireless communications with frequency standards of Super high-Frequency and also power divider is given to one side of patch for previous design and it is simulated and compared with the previous design. Microstrip line edge feeding technique is used in the design analysis. The performance of the designed antenna was analyzed in terms of gain, return loss and surface current distribution with a substrate of FR4_epoxy. Design and performances are analysed using Ansoft HFSS electromagnetic simulator and also to meet the FSS standards.
