摘要
首先分别设计32 GHz宽波束微带天线、混合左右手高功率移相器以及混合左右手串联馈电网络,提出了一种改进的相控阵波束控制方式。该波束控制方式可以降低圆柱体和圆锥体共形相控阵移相器模块的设计难度,达到简化圆柱体和圆锥体共形相控阵设计的目的。作为实例,设计了一个60°扇形的锥体共形相控阵,计算结果表明:该相控阵可以在俯仰面0°≤θ≤90°、滚动面-30°≤φ≤30°范围内实现有效扫描。
First, a microstrip antenna with broad beamwidth, series feed network and composite right/left-handed transmission line （CRLH-TL）phase shifter with high power capacity is designed respectively, which works at 32 GHz. Then,a novel beam steering method of phased array is presented. The method can decrease the complexity of the phase shifter modules in conformal cylindrical and cone-borne phased arrays, and consequently it simplify the design of conformal phased array. Finally, a 60° fan-shaped conformal cone-borne phased array is designed as an example. Numerical results reveal that the 60° phased array can realize effective beam scanning in the range of 0°≤θ≤90° and -30°≤φ≤30°.
