Phase controlled antenna for radar device

摘要

The antenna has several radiators arranged together in a line configuration, with several lines one above the other in the elevation direction. The radiators are supplied with their respective signals via an elevation distribution network (EV), coupled to each line via a phase shifter and phase setting network. The phase shifter and setting network has an associated coupler (K1) with an input gate, an insulation gate coupled to a high frequency (HF) termination, and two output gates, coupled to the respective phase setting devices. There is a second coupler (K2) with input gates coupled to the outputs of the phase setting devices, with the output gates providing two signal outputs which are coupled to supply points at the end of each line.
