摘要

This paper presents a dual-polarized 1×4 antenna array with wide bandwidth and high isolation. The antenna element consists of three metallic layers, a 4×4-unit metasurface (MTS) on the top layer, a patch fed by two ports on the middle layer, and a ground plane on the bottom layer. By exciting different feeding ports, the antenna achieves X-axis linear polarizations (X-LP) or Y-axis linear polarizations (Y-LP). Isolation slots etched on the patch, combined with a via-hole structure, effectively block the coupling between ports and improve port isolation. Experimental results demonstrate that the proposed antenna achieves an impedance bandwidth of 17.4% (4.975–5.925 GHz), with S11<−10 dB and S21<−20 dB. The measured peak gain attains 12.5 dBi.
