“…This allows to be used in several applications such as mobile communications, radars and filters [7]- [10]. The study of the resonant characteristics of High Tc superconducting microstrip antennas has been first studied by [4] using the cavity model. Since the cavity model does not consider rigorously the effects of surface waves and fringing fields at the edge of the patch.…”

In recent years, a great interest has been observed in the development and use 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 equation, the kernel of which is the dyadic Green’s function. Galerkin’s 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.

“…High temperature superconductors (HTS) have been widely used in passive microwave (mw) applications, such as filters 1–3 and antennas 4–7, since the magnitude of their mw surface resistance ( R s ) is much smaller than that of normal conducting metals. Therefore, magnetic resonance imaging and nuclear magnetic resonance pick‐up coils have been designed from HTS.…”

We investigate the microwave surface resistance of an infinitely long type-II superconductor in the critical state carrying transport DC current, in the absence and in the presence of external magnetic fields. Calculations include both different cooling processes and various current and field arrangements.Theoretical results in field-cooled sample show that the microwave surface resistance exhibits an initial slow variation followed by a faster one above a threshold current value. This occurs when the current induced magnetic field generates fluxons of opposite directions on the two sample edges.

“…copper [1,2]. Advantages of using high T c superconductors at high frequencies include [3]: 1) very small losses, which means low-attenuation and low-noise; 2) very small dispersion up to frequencies of several tens of GHz; 3) smaller devices due to the lower losses, which leads to larger integration density and 4) the propagation time can be greatly reduced because of the smaller size and the shorter interconnects.…”

A rigorous full-wave analysis in the Fourier transform domain is carried out in order to obtain the resonant frequencies and half-power bandwidths of the high T c superconducting rectangular microstrip patches over ground planes with rectangular apertures. To include the effect of the superconductivity of the microstrip patch in the full-wave analysis, a complex surface impedance is considered. This impedance is determined by using London's equation and the two-fluid model of Gorter and Casimir. The validity of the solution is tested by comparison of the computed results with previously published data. Variations of the resonant frequency with the high T c superconducting film thickness are presented. Results showing the effect of the temperature on the resonant frequency and half-power bandwidth of the superconducting microstrip antenna with a rectangular aperture in the ground plane are also given. Finally, a comparison between the efficiency of two antennas is presented. For the first antenna, YBCO patch with YBCO ground plane are considered. For the second antenna, the patch and the ground plane are with copper.
