Abstract:
An antenna including a single layer of a high critical temperature copper oxide superconductor, comprising:a single layer of a thin film deposited onto a single crystal substrate;said thin film being constructed of a superconductive compound of the general formula La.sub.3-z Me.sub.z Ba.sub.3 Ca.sub.1-v Nc.sub.v Cu.sub.7 O.sub.16+x, wherein Me is selected from the group consisting of Y, Yb and Na;said Nc is a 2+ion selected from the group consisting of Mg and Cd;said z is about 0 to 2;said v is about 0 to 00.5, with the proviso that at least one of said z and said v is greater than 0;said compound having metallic behavior above the superconducting transition;said compound retaining oxygen when heated in the range of 450.degree. C. to 650.degree. C.; andsaid single layer of a high critical temperature copper oxide superconductor being patterned to complete the device.
