Miniaturized Wideband Low-Profile Antenna Based on Capacitive loading Metasurface
A novel metasurface antenna is proposed with capacitive loading and dual-layer metasurface array. The antenna consists of dual-layer array using different period and four strips are inserted into unit of the upper array. This structure increases surface capacitance, thus reduces operating frequency and make the antenna miniaturized. The proposed antenna with a low profile of 0.064λ0 and a metasurface size of 0.4λ0×0.4λ0 (λ0 is the center operating wavelength in free space) attains 26.2% simulated bandwidth (|S11| < -10dB) with 6.19-7dBi gain at 3.78-4.92GHz. Compared to the traditional metasurface antenna, the antenna size reduced to 30%.
