摘要： Signals are maintained to be in phase at beam input ports of a Rotman lens antenna, and thus scanning at non-step antenna beam angles can be realized without increasing the number of input beams. The present invention provides an antenna beam scan module including: a Rotman lens that has plural beam ports and plural antenna ports; plural antenna elements; relative phase detectors that detect a relative phase difference between the signals input to the adjacent beam ports; phase shifters that offset the relative phase difference between the signals supplied to the adjacent beam ports on the basis of the relative phase difference detected by the relative phase detectors; and switches that select routes of the signals supplied to the beam ports through variable amplifiers, wherein the phase shifters are arranged on alternate routes through which the signals are supplied to the plural beam ports.
摘要翻译：信号在Rotman透镜天线的光束输入端口保持同相，因此可以在不增加输入光束的数量的情况下实现非步进天线光束角度的扫描。本发明提供一种天线波束扫描模块，包括：具有多个波束端口和多个天线端口的Rotman透镜; 多个天线元件; 相对相位检测器，其检测输入到相邻波束端口的信号之间的相对相位差; 移相器，其基于由相对相位检测器检测的相对相位差来补偿提供给相邻波束端口的信号之间的相对相位差; 以及通过可变放大器选择提供给波束端口的信号的路线的开关，其中移相器布置在信号被提供给多个波束端口的交替路径上。
