Abstract: This invention pertains to a lightweight dual-band electronically steered phased array antenna having a multi-layer circuit for supplying DC and a ground plane to RF-on-flex subarrays. A dipole and two additional legs form a four-legged pyramid that stiffens the multi-layer circuit structure and serves as a bonding point to a radome surface. Two of the legs of the pyramid incorporate a low-band V dipole-radiating element. A third leg of the pyramid distributes RF energy to the subarrays via the multi-layer circuit. At the base of the pyramid is an open rectangular frame that accepts the insertion of the multi-layer circuit. An infrared laser transmitter distributes high and low band transmit/receive module control signals to an infrared detector on the opposite side of the subarrays.

Abstract: A lightweight active phased array antenna including modular active electronics assemblies and passive radiating element aperture panels that are integrated into a lightweight support structure of a minimum depth which provides a cooling system for the electronics assemblies. The electronics assemblies and aperture panels are fully accessible from one or both faces of the antenna and can be readily removed/replaced as required.
