ABSTRACT:
A miniaturized circuit for high frequency operation is formed of four successively superimposed dielectric layers, with a microstrip resonance element being sandwiched between two inner dielectric layers which themselves are sandwiched between opposing ground plane layers, and the other dielectric layers being respectively formed upon these ground plane layers. Circuit connection patterns are formed on the outer faces of the latter dielectric layers, and circuit components mounted thereon to form two circuit sections. The microstrip resonance element can be utilized as an inductive reactance element of an oscillator circuit, or as a filter circuit resonator element, and is effectively shielded by the ground plane layers which also effectively mutually isolate the two circuit sections.
