The rise of 5G wireless communication technologies has increased the demand for high-performance antennas with wide bandwidth and high gain. A new high-frequency microstrip patch antenna for 5G networks is presented in this research. Rogers RT5880 substrates have 2.2 dielectric permittivity, 0.0009 loss tangent, and a 0.5 mm thickness used to build the antennas. Utilizing CST Microwave Studio simulates, analyzes, and compares antenna efficiency, bandwidth, gain, reflection coefficient (S11), and VSWR. A 50-microstrip feed line goes to the radiating patch via an inset feed transmission wire. The design was improved to maximize gain, directivity, and bandwidth, which 5G networks need. Antenna Design-I, II, III, and IV had reflection coefficients and VSWRs of –12.55 dB, –54.47 dB, –70.89 dB, –63.29 dB, and 1.617, 1.0038, 1.0005, and 1.0001. Besides, antenna design-I, II, III, and IV exhibited gains and directivity of 7.91dBi, 7.51 dBi, 7.21 dBi, 7.44 dBi, and 8.45 dBi, 8.19 dBi, 7.88 dBi, 8.16 dB, respectively. Design I antennas were 93.6% efficient, while Designs II, III, and IV were 91.7, 91.5, and 91.18%, respectively. The bandwidth of Design-IV is 1.462 GHz, higher than Designs-I, II, and III, which have 1.381, 1.185, and 1.19 GHz, respectively. The four designs investigated in this research achieve a high-efficiency rate of over 91%, which is similar. Despite similar gain and directivity, design IV offers the highest bandwidth of the three designs. This study reduces return loss and improves antenna gain, directivity, and bandwidth. The antenna's wireless communication technology offers wirelesses, cost-effectiveness, and simple remote communication, making it ideal for 5G wireless applications.
