1. An apparatus comprising:
- an antenna element;
a ground;
a metal part having non-antenna related functionality and configured to be non-moveable relative to the ground;
a plurality of conductive connections providing galvanic dc current paths between the metal part and the ground; and
a further conductive connection comprising a filter electrically interconnected between the metal part and the ground wherein the filter is a band-stop filter having a very high impedance at a particular frequency band.
