一种C波段压控超材料表面
A C-band voltage controlled metamaterial surface
摘要
Abstract
A C-band transmittance adjustable voltage controlled metamaterial surface is proposed. The metamaterial surface is composed of novel adjustable metamaterial units with varactor diodes. By adjusting the DC bias voltage, the capacitance value of the varactor diode is changed so that the electromagnetic properties of the metamaterial unit are adjusted. In this paper, the scattering parameters, effective permittivity and effective permeability of the metamaterial unit are simulated and calculated. The metamaterial unit is designed to resonate from 5.2 GHz to 5.6 GHz. In order to verify the property of the designed metamaterial unit, the voltage controlled metamaterial surface is adopted in adjusting the far-field radiation pattern of a microstrip antenna. The DC bias voltage of 0.5 V to 10 V is applied to the designed voltage controlled metamaterial surface operating at 5.4 GHz, and the transmittance changes about 20 dB by changing voltage.关键词
