Abstract

A phased array antenna in which a plurality of blocks each having a plurality of transmitter modules are arrayed, includes: a front plate that includes a plurality of flow paths of a refrigerant therein; and an element feeding layer that includes a plurality of antenna elements respectively connected to the transmitter modules and that is placed in close contact with one surface of the front plate. Each of the blocks includes a heat spreader that is placed in close contact with the other surface of the front plate. The transmitter modules are mounted on the heat spreader. Heat generated in the transmitter modules is transferred to the refrigerant via the heat spreader and the front plate.
