Progressive Phase-Rotman-Turner lens feed transmission line network

A progressive phase feed transmission line network for use with a Rotman-Turner lens is composed of a plurality of feed ports for receiving or transmitting energy from or to the lens, a pair of control ports, a plurality of different sets of transmission line segments with the segments in the same sets being of substantially equal lengths, and a plurality of power directors for splitting or combining energy depending upon whether the network is operating in a receive or transmit mode. Different phase delays are interposed in the network to provide a passive arrangement which can operate in the receive mode to determine directionality of energy received by an antenna array and fed through a Rotman-Turner lens to the transmission line network or can operate in the transmit mode in a combination with adjusting of a phase shifter to directionally steer the energy launched into space by the antenna array after being fed from the network through the lens to the antenna array.
