设计了一种64单元、30 GHz共馈微带天线阵，并在0.254 mm（10 mil）厚的铝酸镧衬底上制作了天线阵。一个天线图案由金膜制成，第二个图案使用TlCaBaCuO高温超导体。两种天线都使用沉积在基板背面的金接地层。增益和辐射模式进行了测量，在室温下，在crogenic温度的天线。观测结果与简单模型的损耗和微波波束宽度吻合良好，超导天线的增益为20.3 dB，波束宽度为15度。天线损耗仅为1.9 dB。<<ETX>>
A 64-element, 30-GHz microstrip antenna array with corporate feed network was designed and built on a 0.254-mm (10-mil) thick lanthanum aluminate substrate. One antenna pattern was fabricated from gold film, and a second pattern used TlCaBaCuO high-temperature superconductor. Both antennas used gold ground planes deposited on the reverse side of the substrate. Gain and radiation patterns were measured for both antennas at room temperature and at cyrogenic temperatures. Observations agree well with simple models for loss and microwave beam width, with a gain on boresight of 20.3 dB and beam width of 15 degrees for the superconducting antenna. The antenna loss is only 1.9 dB.<<ETX>>
