摘要
采用四端口网络理论分析了极化方式、介电常数与损耗角正切对天线罩透波率的影响,讨论了石英/氰酸酯玻璃钢复合材料的传输特性。数值仿真和实测结果表明,在频带1.2～18 GHz,水平方位角-40°～40°范围内,厚度为1.8 mm的石英/氰酸酯平板功率传输系数均大于60%,表现出良好的宽频特性。
The effects on power transmission coefficient of polarization,dielectric constant and loss angle tangent value are discussed by Four-port network theory.The transmission efficiency of Quartz/CE is analyzed.Simulation and measured results show that,when the frequency is 1.2～18 GHz and azimuth angle is-40°～ 40°power transmission coefficient of the plate with thickness of 1.8mm is greater than 60%,showing favorable broadband characteristics.
