Abstract (en)
Apparatus comprising a radiofrequency filter (40) is disclosed, which comprises an elongate electrical conductor (33) having a meandering shape from which extends one or more electrically conductive stub elements (47) which acts as a resonator. The stub element has a wider cross-sectional profile than a cross-sectional area of the electrical conductor. In another embodiment, the stubs elements partially encircle the meandering conductor. Also disclosed is a method of manufacture of such a radiofrequency filter using a sheet-like conductive material.
