ABSTRACT:
A transmission line structure includes first and second mutually separated strip conductors lying on an upper side of an upper dielectric sheet, and a ground conductor juxtaposed with the lower side of the upper dielectric sheet. A further strip conductor lies on a lower side of a lower dielectric sheet, with its ends registered with the ends of the first and second strip conductors. A gap in the further strip conductor is controllably bridged by a MEMS switch element, which may lie below the second dielectric sheet or in a cavity defined in the second dielectric sheet.
