Abstract:
A phased array antenna, comprising:an array of antenna elements having multiple layer sections;an array of phase shifter sections each one thereof being associated with a corresponding one of the antenna elements in the array thereof;an electrically and thermally conductive cold-plate having a pair of opposing surfaces, one of the opposing surfaces having the array of phase shifter sections mounted, and thermally coupled thereto and an opposite one of the pair of opposing surfaces having thermally conductive posts with proximal ends thermally connected to the opposite one of the opposing surfaces and projecting outwardly therefrom;a heat sink plate thermally coupled to distal ends of the posts, anda power/radio frequency energy distribution section mounted to said opposite one of the pair of cold-plate surfaces for distributing power and radio frequency energy among the phase shifter sections mounted to the cold-plate.
