MATLAB's Simulink and the Antenna Toolboxes are used in this research to build and simulate a 2.45 GHz square patch microstrip antenna. Microstrip patch antennas' advantages and disadvantages will be discussed in detail in the introductory portion of this paper's brief history of the development of antennas for wireless communication systems. The rectangular microstrip patch antenna, coding, and outcomes of the developed microstrip patch antenna are all covered in this work. Antennas are critical components of every wireless communication system. Reduced antenna size, weight, and cost with good performance and minimal return loss are the requirements for this technique (RL). The MPA (microstrip patch antenna) may be utilized to achieve these specifications. A flare retardant substance is used as a substrate for the proposed MPA. Using an RL of -38.86 decibels at a frequency of 2.3933 GHz, the MPA was found to be capable of operating with a BW (bandwidth) of 57 MHz and a VSWR of 1.002. The antenna's volume is 75.805 x 57.223 x 1.6.
