In this paper, a Microstrip Patch Antenna (MPA) is about to be designed. A dielectric material known as the substrate is sandwiched between a metallic patch and ground in an MPA. In comparison to the substrate and ground, a patch is smaller in size. The resonant frequency and dielectric constant value affect the size of a microstrip patch antenna. The proposed technology is a multi- input and multi-output microstrip patch antenna technology for wireless communications. The term "multiple inputs and multiple outputs" (MIMO) refers to a wireless technology that transfers more data between the transmitter and receiver at once to speed up data transmission and reduce mistakes. In essence, this idea refers to wireless network technology enabling access points or wireless routers to have many antennas. Simulating all antenna parameters, such as VSWR, balance, efficiencies, far field, and s-parameters, using CST Microwave Studio is the only way to verify the proposed antennas' performance.
