Abstract
A superconducting antenna device of an embodiment includes an array antenna made by stacking a flat antenna having one or more antennas made of a superconducting material and a ground pattern on a low-loss dielectric substrate from a short wave band to an extremely-high frequency band, a vacuum chamber configured to accommodate the array antenna, a refrigerator configured to cool the array antenna, and a vacuum insulating window configured to pass an electromagnetic wave from a short wave band to an extremely-high frequency band in a direction of directivity of the array antenna in the vacuum chamber.
