Antennas play an indispensable role in radio engineering. The system between the electric currents flowing in the metal conduits and the radio waves flowing through space is constructed using a transmitter or receiver. A microstrip patch antenna was invented in 1953. They also became the area of interest to the researcher, as they raised the interest of the researcher owing to their good features, such as low profile, cheap to manufacture, light, and easy to install. Awareness began in 1970. Microstrip patch antennas are used in airplanes, spacecraft, satellites, and wireless communications. In recent communication devices, such as smartphones, Wi-Fi routers, and 5G mobile phones, the number of users has increased significantly in wireless communication and the application of microstrip patch antennas in communication devices. The large dimensions of antennas were eliminated by small antennas in the early days, as large antennas were used; however, as technology evolved, the size of antennas was reduced. In recent decades, researchers have focused on microstrip patch antennas to determine how to attain compact size and large bandwidth. This study provides a detailed analysis of the antenna designs and their different feeding methods and extended advanced research on the different types of antennas and their enhancement strategies to attain a small scale of the antenna to Sub-6 GHz to support 5G using simple antenna design techniques such as patch and ground slot-loading.
