Abstract

A multilayer printed radiator for a phased antenna array of a user terminal for Ka-band satellite communications is considered. The design of the radiator is described and the results of calculations of the radiator model are presented. The radiator operates on circular polarization in the frequency range of 29–30 GHz and has a scanning area in the form of a cone with a solid angle of ±65 degrees. To reduce the level of cross-polarization, groups of four radiators with sequential rotation of 90 degrees are used. The results of calculations for such a group of radiators in the Floquet channel condition are presented.

宽角扫描ka波段相控阵圆极化多层印刷辐射体
研究了一种用于ka波段卫星通信用户终端相控天线阵列的多层印刷辐射体。介绍了散热器的设计,并给出了散热器模型的计算结果。该辐射器工作于29-30 GHz频率范围内的圆偏振,扫描区域为圆锥体形式,立体角为±65度。为了降低交叉极化的水平,我们使用了一组四个连续旋转90度的散热器。给出了在Floquet通道条件下这组辐射体的计算结果。
