✦ Synopsis

A full-wa¨e analysis of parallel-coupled microstrip antennas with superconducting films on anisotropic substrates is de¨eloped in the spectral domain, by using a combination of the moment method, Hertz ¨ector potentials, and the model of two fluids of Gorter and Casimir. The resonant frequencies of coupled superconducting microstrip patches are determined for the e¨en 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 obser¨ed between our results and the measured ones, which are a¨ailable in the literature for single HTS microstrip patch antennas on isotropic substrates.
