Today, one of the key topics of study in the field of communication systems is wireless technology, and no studies of communication systems is complete without a grasp of how antennas work and are made. Numerous scholars have investigated antennas for various wireless communication systems. The conceived, created, and tested omnidirectional microstrip patch antenna (MPA) is the subject of this study. The antenna's operational bandwidth is a good fit for a variety of applications. Microstrip patch antennas are the ideal option for communication systems engineers due to its effectiveness and advantages, which include low cost, low profile, and low weight. Due to the fact that they may combine with microwave circuits, they are ideal for applications like cell devices, many others, including WLAN applications and navigational systems. In this project, a small rectangular patch antenna is created. The research of a two- or four-element array antenna has been the focus of the work's last section. The optimization of a 1.9GHz rectangular probe fed patch antenna in the design and simulation of patch antennas. According to experimental findings, the voltage standing wave ratio, insertion loss and capacity.
