Abstract

Microstrip patch antennas have recently garnered significant traction in the wireless communication field due to their cost-effectiveness, low profile, and ease of fabrication on circuit boards. In this context, an ultra-wideband (UWB), optimized, compact, octagonal-shaped microstrip patch antenna (OMPA) designed for multiple 5G, WiFi, and potential 6G uses are presented. The proposed antenna features dimensions of 21 × 23.52 × 1.6 mm³, corresponding to electrical measurements of 0.24λ × 0.27λ × 0.026λ. λ represents the free-space wavelength at the resonant frequency of 3.5 GHz. Also, the antenna is printed on a commercially available epoxy substrate with a 4.3 relative permittivity with the ground and radiating patch made of copper of 0.035 mm thickness. In addition, a partial ground structure is used to obtain omnidirectional radiation and miniaturization, while the rectangular slot in the ground greatly enhances the proposed antenna’s bandwidth. After the fabrication and testing of prototypes, the proposed antenna works throughout a frequency range. starting at 3.14 GHz to 13.5 GHz, reaching the entirety of 10 GHz of band with two resonant frequencies of 3.8 GHz and 8 GHz. With its high average efficiency, excellent reflection coefficient profiles and the optimal Voltage Standing Wave Ratio (VSWR) values, the optimized OMPA is a suitable antenna for high data-rate applications in 5G wireless communications operating at sub-6 GHz and sub-7 GHz. This research also highlights the antenna’s potential integration into future 6G standards.
