Abstract
An antenna device includes a plane-type antenna element, a heat insulation container for blocking heat entering from the outside, the heat insulation container having a radio-wave window allowing a radio wave to pass therethrough, and housing the plane-type antenna element, a waveguide housed in the heat insulation container and arranged between the radio-wave window and an antenna pattern formation surface of the plane-type antenna element, and cooling means for cooling the plane-type antenna element. The waveguide is shaped and dimensioned so that the directivity of the plane-type antenna element is enhanced, and a superconducting film is used for the antenna pattern of the plane-type antenna element.
