PROBLEM TO BE SOLVED: To enable modules to be assembled or disassembled from behind an antenna device by a method wherein a pair of cooling plates where cooling liqiud flows are provided at a position to sandwich a pair of modules which supply power to an antenna element, and a pressing means is provided between the modules so as to bring them into close contact with the cooling plates. SOLUTION: A cooling structure is equipped with a coupler which feeds and exhausts a cooling liquid and cooling plates 8 where a cooling liquid is circulated inside being distributed by a manifold which collects and distributes the cooling liquid. A module 9 which releases heat as it amplifies signals and is required to be cooled down to a certain temperature or below is provided in each surface of the cooling plate 8 so as to come into close contact with it by a pressing metal 11. The module 9 can be disassembled through such a manner where the pressing metal 11 for the module 9 to replace is dismounted from behind an antenna device to disassemble the module 9 from a state where it is kept in close contact with the cooling plate 8, and then the module 9 is pulled out. Therefore, the module 9 can be disassembled or assembled from behind the antenna device.
