Abstract—The microstrip patch antenna is commonly recognised for its diversity in term of achievable structures that make them appropriate to a wide variety of applications. The lightweight and compact size of the structure make these types of antennas suitable for use besides the microwave embedded circuits two more of their diverse benefits. In this paper, a modified design of the rectangular Microstrip Patch Antenna (MPA) beside edge feeding technique is simulated and optimised to cover a multi-band of the microwave frequency. The proposed antenna has been analysed based on the High-Frequency Structure Simulator (HFSS) using an FR-4 substrate. The introduced MPA design constitutes of a radiating patch from copper metal with a copper extension directly coupled to the lowest edge of the radiating patch via three stubs to covering three operating frequency bands: f1= 6.19 GHz (6.13-6.26 GHz), f2= 7.63 GHz (7.55-7.7 GHz), and f3=10 GHz (9.3-10.82 GHz). Consequently, the obtained results of the modified antenna design show a good gain with S11<10 dB in the previous operating frequency bands, which are suitable for most wireless communication applications.
