A full‐wave analysis of parallel‐coupled microstrip antennas with superconducting films on anisotropic substrates is developed in the spectral domain, by using a combination of the moment method, Hertz vector potentials, and the model of two fluids of Gorter and Casimir. The resonant frequencies of coupled superconducting microstrip patches are determined for the even and odd resonating modes, as a function of the temperature and the structural parameters. The radiation pattern for a planar HTS microstrip antenna array is also shown. An excellent agreement was observed between our results and the measured ones, which are available in the literature for single HTS microstrip patch antennas on isotropic substrates. © 2000 John Wiley & Sons, Inc.
