Abstract


This study describes the design, modelling, and performance assessment of an inset fed microstrip patch antenna (MPA) operating at a center frequency of 28 GHz that was created especially for 5G millimeter-wave (mmWave) applications. Key performance characteristics are significantly improved by the suggested antenna's strategic use of an inset feed mechanism to increase impedance matching and reduce reflection losses. According to thorough calculations carried out using HFSS software, the inset-fed antenna achieves a return loss of –29.8997 dB, demonstrating good impedance matching. Additionally, the design successfully covers the target frequency range needed for high-speed 5G communication systems with a large impedance bandwidth of 1135 MHz (27.47-28.605 GHz). A peak gain of 7.1328 dBi is another feature of the antenna that is necessary to provide adequate signal strength and coverage in small wireless devices. A comparison study is conducted against a traditional non-inset feeding MPA of comparable size in order to highlight the advantages of the inset-fed method. Findings validate the efficacy of the feeding approach by demonstrating that the inset-fed structure provides much increased radiation performance, a wider bandwidth, and dramatically enhanced return loss. Because of its small size, simplicity of construction, and effective radiation properties, the antenna is ideal for incorporation into systems and devices that will support 5G in the future. The feasibility of using inset-fed MPA for high-frequency wireless communication in the millimeter-wave range is confirmed by this work.
