A signal distribution network for the planar array antenna of a monopulse radar system comprising a plurality of array elements, a sum channel feed and a difference channel feed, each feed being split to define an even number of transmission lines N, the elements of the array comprising N groups, each group being coupled to both channel feeds via a different pair of transmission lines such that the lines of each pair communicate respectively with the sum channel and the difference channel, the elements and the lines being mutually cross coupled by directional couplers such that each element receives an appropriately weighted signal from each channel feed. |
