Résumé:
of new materials in microwave technology. Particularly, a special interest has
been observed in the use of superconducting materials in microwave
integrated circuits, this is due to their main characteristics. In this paper, the
complex resonant frequency problem of a superconductor patch over Ground
Plane with Rectangular Aperture is formulated in terms of an integral
procedure is used in the resolution of the electric field integral equation. The
surface impedance of the superconductor film is modeled using the two
fluids model of Gorter and Casimir. Numerical results concerning the effect
of the thickness of the superconductor patch on the characteristics of the
antenna are presented.
