Abstract: The invention relates to an electronic structural element (1) with a first and a second base plate (2a, 2b), as well as a coupling plate (3), wherein, between the first base plate (2a) and the coupling plate (3), a first electrical capacitor (C1) is formed, and, between the second base plate (2b) and the coupling plate (3), a second electrical capacitor (C2) is formed, so that the first and the second electrical capacitors (C1, C2) form an electrical series capacitor (Cs) between the first and the second base plates (2a, 2b). According to the invention, the coupling plate (3) is divided into a plurality (N) of mutually non-contacting strips (6), wherein the first and the second electrical capacitors (C1, C2) are in each case divided into a plurality (N) of electrical elementary capacitors (Ce), and, by means of the strips (6), a plurality (N) of parallel-connected, electrical elementary series capacitors (Cse) is formed between the first and the second base plates (2a, 2b).

Abstract: A ceramic multilayer construction includes three resonators designed as parallel strip lines that are capacitatively or magnetically coupled to each other. All circuit components are implemented in the form of metallizations in multilayer construction. Capacitative couplings are implemented by coupling capacitors. The strip line resonators are shortened by shunt arms to ground having grounding capacitors arranged therein.
