Abstract
The power dependence of radiation efficiency of two circularly polariz ed superconducting microstrip antennas, fabricated from YBCO/LaAlO3 fi lms, was investigated. The study showed that this kind of HTS antennas could withstand 5W input power level, beyond which a sharp drop in th e radiation efficiency was observed.
