Abstract :
A high-T/sub c/ superconducting (SC) active antenna with a corner reflector is found to be useful for detecting electromagnetic waves (f=9.55 GHz). The SC active antenna is a new type of antenna which consists of material properties and antenna properties. The microwaves with fixed polarizations are radiated to the SC active antennas, and the detectivities and the directivities were confirmed experimentally. With the use of the corner reflector, the sensitivity and the directivity can be improved.<>
