Abstract
This paper presents the fabrication of a dual-polarized, single-feed, transmissive metasurface antenna, designed for enhanced performance in wireless communication systems. The antenna is specifically optimized for dual-polarization performance, targeting the mitigation of multipath propagation effects, a prevalent issue in wireless networks. It features an equal power distribution between Vertical and Horizontal polarizations and achieves a 21.93 dBi gain at a center frequency of 28 GHz. A comprehensive theoretical analysis delves into the underlying physical mechanisms of the metasurface's polarization conversion capabilities. This involves a thorough investigation of the surface current distribution and a detailed geometric study. The paper culminates with the practical realization and experimental validation of the proposed antenna design. Measurements confirm a close alignment between simulated results and actual performance, underscoring the antenna's efficacy in real-world scenarios for fifth-generation (5G) application.
