The design, simulation, and analysis of a 3.5 GHz rectangular microstrip patch antenna (RMPA) have been carried out for this research article. The substrate material employed for the design is a lossy form of fr-4, which has a thickness of 0.5 mm, a dielectric permittivity of 4.3, and a loss tangent of 0.0005, respectively. The antenna receives power through a feeding line with an impedance of 50 Ω. The simulation was ultimately finished off with the help of some computer simulation tools. Following completion of the simulation, the findings revealed a directivity gain of 6.05 dBi, a voltage standing wave ratio (VSWR) of 1.0607, and a bandwidth of 144.1 MHz. The return loss was determined to be -30.611 dB. The suggested antenna's primary purpose was to attain a standard value for the VSWR while lowering the return loss. This antenna improves directivity gain and bandwidth and has applications in radars, mobile phones, and wireless local area networks (WLANs). The results of this proposed antenna were superior to those of a variety of studies that had been published in the past.
