Abstract:
1. A modular active radiating device for electronically scanned array antennas comprising: a first set of components including active radiating elements comprised of transmit/receive modules, radio-frequency switching devices and radiating elements; a second set of components including a thermal stabilization system; a third set of components including a supply and control system; said first, second and third sets of components disposed on different separable planes united to form a multi-layer structure, vertical interconnections connecting elements of said third set to elements of said first set going across said second set; said first set including: the multi-layer printed circuit board being formed by a plurality of contiguous flower modules; each flower module being formed by two or more quadrangular elementary petal portions placed side-by-side; each petal portion constituting a single phase center and comprising: an only active radiating element comprised of: contacts for said vertical interconnections, arranged close to one or more sides of said petal portions, along only a portion of each of said one or more sides, in such a way that the contacts are at least partially facing to each other between side-by-side petal portions, so that said vertical interconnections can cross said second set and connect said first set to said third set without jeopardizing the continuity of the thermal stabilization system.
