Abstract :
A superconducting 4-element microstrip array antenna operating at 30 GHz has been designed and fabricated on a lanthanum aluminate (LaAlO/sub 3/) substrate. The experimental performance of this thin-film Y-Ba-Cu-O superconducting antenna is compared with that of an identical antenna patterned with evaporated gold. Antenna patterns show good agreement with predicted patterns, and efficiency measurements of these antenna show an improvement of 2 dB at 70 K in the superconducting antenna over the gold antenna.<>
