Abstract

This paper presents a design and analysis of a compact inset-fed polyimide-based substrate rectangular patch antenna for a fifth generation (5G) system. The proposed design operates at a resonant frequency of 28 GHz and uses copper material for ground and radiating patch elements with polyimide plastic material has a dielectric constant of 3.5 for the substrate. The thickness of the substrate was fixed at h= 0.27 mm. While the thickness of the patch and ground was kept at t = 0.035 mm. The Computer Simulations Technology (CST) program was used to simulate and evaluate the performance of the proposed antenna. It shows a returns loss value of -17.68 dB. Voltage standing wave ratio (VSWR) of 1.3. Bandwidth (BW) value of 1.427 GHz. Gain (G) value of 5.406 dBi and radiation efficiency 86%. These obtained results are used to be compared with similar existing designs in the scientific literature.
