Abstract (en)

[origin: EP0902497A2] The resonator has a pair of conductor paths (L1,L2) which are electrically connected together at a number of spaced points. One or more of the connections (V) can be interrupted in dependence on the required resonator frequency. One of the conductor paths (L1) can be provided by a microstrip or a stripline, with the connections provided by circuit board through connections. The other conductor path (L2) is connected to a reference potential (M).
