This article presents a novel S/C/X band antenna specifically designed for 5G and beyond applications. The antenna's performance is thoroughly analyzed through comprehensive simulations using CST Microwave Studio on an FR-4 substrate, measuring 10λ × 14λ × 0.014λ (where λ is calculated at a lower resonance frequency). The proposed design displays remarkable characteristics, boasting an outstanding impedance bandwidth of 124% and an impressive return loss of −38 dBi. Its operational frequency ranges from 2.8 to 12 GHz, with a central frequency of 7.4 GHz. Throughout this range, the antenna maintains stable polar patterns, ensuring consistent and efficient performance with a wide gain of 3.98 dBi and an impressive efficiency of 84.2%. This antenna proves to be well-suited for diverse applications, including S-band: 3.1-4.2 GHz, C-band: 4.4-5.0 GHz, X-band: 8.0-12.0 GHz, and 5G and beyond communication. The innovative features of this S/C/X band antenna offer significant potential for advancing wireless communication technologies.
