Active electronically scanned array aerial for airborne radar application, has supply line that is prolongation of printed circuit line of transmission and reception module and contained in plane perpendicular to plane of radiating element

摘要

The aerial has a radiating element (1) i.e. multilayer microstrip, placed on a substrate and supplied with radiofrequency signals that are provided by a transmission and reception module (5). The radiating element is excited by an impression type supply line (2) through a proximity electromagnetic coupling of the element. The supply line is prolongation of a line of a printed circuit of the module and contained in a mass plane (3) perpendicular to a mass plane (8) of the radiating element. The supply line is placed outside the module and partly or totally integrated in support foam.
