Claim 0:
1. A printed circuit board antenna, comprising:
a printed circuit board having an outer layer;
an electrically conducting antenna structure disposed on said outer layer of said printed circuit board, wherein said electrically conducting antenna structure has a first resonance frequency;
an electrically conducting feed line leading to said electrically conducting antenna structure; and
an electrically conducting reference region disposed on said outer layer, wherein said electrically conducting reference region completely encloses said electrically conducting antenna structure with an exception of an insulating feed recess for said electrically conducting feed line and an insulating web recess, wherein said insulating web recess being disposed on a side of said electrically conducting antenna structure facing away from said electrically conducting feed line, and wherein said electrically conducting reference region having a reference region web on a side of said electrically conducting antenna structure facing away from said electrically conducting feed line, which forms a resonator with a second resonance frequency coupled capacitively to said electrically conducting antenna structure.
