Full wave modelling of hts dual mode patch filters and staggered coupled-line filters

Abstract

In order to obtain high-power hzuidlirig, dual-nlode patch HTS filters have been analyzed through Green’s function rad desegmentation techniques. A precise circuit model has been obtained and applied to the filter design process, and useful design curves relating filter parameters and physical dimensions of the square patch have been plotted. Several designs have been made using them and then optimized with the Method of Moments in the Spectral Domain. For higher order circuits, staggered coupled-line HTS filters have been considered. The designs have been made using the method of moments to compute the coupling capacitances, and then optimized with the Method of Moments in the Spectral Domain. One dual-mode patch filter and ane staggered coupled-iine filter have been fabricated on a YBCO film. Measurements agree well with simulations.
