Multilayer-structure device with vertical transition between a microstrip and a stripline

摘要

Described herein is a device with vertical transition (1) having a plurality of layers set on top of one another, which define a first transmission line (2) and a second transmission line (3); the first transmission line (2) has a first conductive path (5) and the second transmission line (3) has a second conductive path (10); an electrical connection structure (20, 21) extends vertically through one or more of the layers set on top of one another and provides the connection between the first conductive path (5) and the second conductive path (10). The electrical connection structure (20, 21) generates a condition of resonance for a signal travelling in the first conductive path (5) and/or second conductive path (10) and having a frequency selected in a band of pre-set frequencies.
