Abstract
This paper presents an advanced design of a compact dual-port printed meandered log-periodic monopole array (PMLPMA) antenna, enhanced with an octagonal-ring-shaped frequency selective surface (FSS) layer, specifically targeting 28 GHz broadband applications for 5G and beyond. The proposed antenna system prioritizes optimized gain, wideband efficiency, and enhanced radiation performance in the millimeter-wave (mmWave) frequency range. To ensure compactness and high performance, the dual-port configuration is designed to achieve improved polarization diversity, while the octagonal-ring FSS layer effectively mitigates surface wave effects and reduces mutual coupling, thereby boosting directivity and front-to-back ratio. This design aims to meet the rigorous demands of 28 GHz communication systems, offering a compact, high-gain antenna solution that is well-suited for integration in advanced wireless communication platforms.
