A Broadband Low-Profile Dual-Polarized Antenna Based on a Metasurface

Year: 2025

Type: article

Abstract: This article presents a wideband low-profile dualpolarization antenna based on a metasurface (MS).The antenna consists of a 4 × 4 metasurface array made up of 16 circular metal patches, a radiating patch, and a metallic ground plane.The metasurface excites the surface waves of the radiating patch to generate multiple resonant points, thereby broadening the antenna bandwidth.In addition, two rectangular cross-slot structures at the center of the patch enhance port isolation.Finally, a prototype with dimensions of 46 mm × 46 mm × 3.2 mm (1.28λ₀ × 1.28λ₀ × 0.88λ₀) was fabricated.Measurement results show that the antenna achieves a return loss better than -10 dB and an isolation better than -16 dB within the operating bandwidth of 6.38-10.3GHz.It can be concluded that the experimental results of the antenna are in good agreement with the simulation results.
