Exploring the Applications of Future 6G Antenna Designs: A Literature Review

Abstract

This review covers advanced antennas for 6G and THz. It looks at various antenna designs: SRR slotted microwave array, RCA, Cassegrain, circular lens, WHEMS, matrix arrangement, CP horn, Quasi Yagi-Uda, patch, transmission array, Vivaldi patch. It covers material, frequency range, and specifications. Additionally, it talks about modern fabrication methods like wire-cut EDM, PCB and LCP, Topas, 3D printing, laser drilling, and CNC machining. PCB has demonstrated promise for Vivaldi, WHEMS, and patches, particularly in terms of gain and bandwidth. But there are still many research challenges to develop new fabrication methods and antenna architectures to meet 6G requirements. This paper highlights the need for smart and adaptive antennas for high bandwidth, efficiency and seamless connectivity for next gen wireless.
