摘　　要：本文围绕1种新型的微波材料在四臂螺旋天线方面的应用展开研究。这种材料有着相对介电常数等于磁导率的特点,可以缩短天线的电长度,同时抑制反射,可应用于天线的小型化设计。本文首先分析了该介质缩小天线尺寸的原理,之后将其运用在四臂螺旋天线上,进行了相关仿真,参数优化。利用这种方法,将四臂螺旋天线在高度上缩小了20.0%,直後上缩小了28.6%。This paper focuses on the application of a new type of microwave material in Quadrifilar Helix Antenna(QHA).This kind of material has the characteristic that the relative permittivity is equal to the magnetic permeability,which can shorten the electric length of the antenna and restrain the reflection,and can be applied to the miniaturization design of the antenna.In this paper,the principle of reducing the size of the antenna with this dielectric is firstly analyzed,and then it is applied to QHA,and relevant simulation and parameter optimization are carried out.With this method,the QHA is reduced by 20.0% in height and 28.6% in diameter.
