Abstract

A 4.5GHz circularly polarized YBCO microstrip antenna was designed and fabricated. Measurements showed that at 77K the superconducting antenna had about 3dB gain improvement over the comparable silver antenna, in agreement with the calculated results using the modified Green function method.

Abstract

The power dependence of radiation efficiency of two circularly polarized superconducting microstrip antennas, fabricated from YBCO/LaAlO3films, was investigated. The study showed that this kind of HTS antennas could withstand 5W input power level, beyond which a sharp drop in the radiation efficiency was observed.
