本文介绍了2-18 GHz和18-40 GHz背腔螺旋天线的设计过程。通过改变天线参数，研究了天线的驻波比和轴比特性。对于2-18 GHz螺旋天线，采用了固体吸波材料和Marchand Balun。将制作的天线的测量结果与仿真结果进行了比较。对于18-40 GHz的天线，考虑了具有可变损耗正切的蜂窝吸振器，研究了改善驻波比和轴比特性的方法。
In this paper, the design procedure of the 2-18 GHz and the 18-40 GHz cavity-backed spiral antenna is described. By varying the antenna parameters the VSWR and the axial ratio characteristics of the antenna are investigated. For the 2-18 GHz spiral antenna, the solid absorber and the Marchand balun are applied. The measured results of the fabricated antenna are compared with the simulated ones. For the 18-40 GHz antenna, the honeycomb absorber having variable loss tangent is considered in simulation to investigate for improvement of the VSWR and the axial ratio characteristics.
