基于支节容性加载的小型化低剖面超表面天线
Miniaturized low-profile metasurface antenna using capacitive loading
摘要
Abstract
A miniaturized metasurface antenna using capacitive loading is investigated. First, anovel miniaturized metasurface unit cell is proposed.By introducing a pair of capacitive-loading strips inserted along the diagonal of a square patch, a size reduction of 55％ can be achieved for this miniaturized unit cell.Furthermore, a compact metasurface antenna of a 4×4 array is designed using the miniaturized unit cells, which is fed by a slot structure.The radiation mechanism of the metasurface antenna is revealed and explained using a characteristic mode analysis (CMA).To validate the design, a prototype of the proposed antenna is fabricated and measurements are taken.The measured-10 dB impedance bandwidthis 21. 7％, while a gain of 6 dBi is observed within the operating bandwidth.关键词
