The inset-feed rectangular patch microstrip antenna is proposed as an effective solution for 5G communication applications that require large bandwidth and high data transmission rates. This antenna is designed with commonly used FR-4 substrate material and is easy to mass-produce. In this design, rectangular slots are integrated to extend the bandwidth to 3 GHz, which is in line with the needs of modern communication applications. The antenna performance shows excellent results, with a return loss value of -37.45 dB, VSWR value of 1.02, and directivity of 13.57 dBi. Simulation and analysis were performed using CST Studio Suite software, which provided optimal results with antenna patch dimensions of 24 mm × 12 mm. The results indicate that this microstrip antenna is a good choice for 5G communication applications, especially in meeting the needs of wide bandwidth and high transmission efficiency. The implication of this research is further development of microstrip antenna design to support future communication technology.
