This article presents a compact multi-band microstrip patch antenna designed for 5G, Ku, and K-band applications. The antenna operates at 3.5 GHz and 15.6 GHz, supporting 5G communications (3.3–3.6 GHz) and satellite applications (15.6–20 GHz). Fabricated on an FR4 substrate (εr = 4.3, tan δ = 0.025) with dimensions of 13 × 10 × 1.6 mm3 (0.15λo × 0.12λo × 0.02λo), where λo represents the wavelength at the lower frequency of 3.5 GHz, the antenna achieves return losses of −19 dB and −39 dB at the respective frequencies, with peak gains of −2.8 dBi and 3.7 dBi. The design’s consistency is validated through a comparative analysis with recent studies. The antenna was placed near the ear and mouth area of a human head phantom model to perform a comprehensive SAR analysis. SAR analysis confirms compliance with safety standards, maintaining SAR levels below 2 W/kg. The proposed design demonstrates promising performance for modern communication systems. © (2024), (Electromagnetics Academy). All Rights Reserved.
