Abstract

The evolution from 4G to 5G introduces several design challenges, including spectrum sharing, significantly wider operating bandwidths, and advanced antenna design. To meet the demands of 5G communication, antennas must exhibit compact geometry, an efficient and well-matched feeding mechanism, and compatibility with large-scale manufacturing. This paper presents the design and optimization of a microstrip antenna operating at the 28 GHz band. The proposed antenna undergoes iterative modifications, focusing on the feed line configuration and radiating patch geometry to enhance performance. At each stage, key performance metrics including S11, gain and radiation pattern are thoroughly evaluated. Furthermore, the impact of geometric irregularities introduced along the feed line plane on the antenna’s resonant behavior, gain, and radiation profile is systematically investigated. All simulations and parametric studies are performed using ANSYS HFSS, and the antenna’s overall performance is assessed based on the obtained electromagnetic simulation results.

Keywords: NR, 5G, MPA, VSWR, Tapering.
