Abstract
Disclosed is a device for supply to the radiating elements of an array antenna with electronic scanning, notably applicable to an MLS type landing system. The disclosed antenna has as many (n) phase-shifters as it has radiating elements each of the phase-shifters being connected to a plurality (m) of neighboring radiating elements forming a sub-array. The sub-arrays are interleaved so that each of the radiating elements is supplied by means of m phase-shifters. As a result, an array antenna with very small minor lobes is obtained.
