Superconducting Microstrip Antenna

Abstract:

Resonant characteristics of microstrip antennas with superconducting films is presented. The analysis is based on a full electromagnetic wave model with London's equations and the two- fluid model. It is shown that the full-wave analysis presented here gives numerical results which are in excellent agreement with the measured data available in the literature. Re- sults showing the effect of the temperature on the resonant frequency and half-power bandwidth of superconducting microstrip antenna are given. Variations of the resonant frequency with the high Tcsuperconducting film thickness are also presented.

Keywords: Cross-correlation function, Hilbert transform, NDT, Split spectrum techniques, Ultrasonics
