| Zusammenfassung: | A printed circuit board antenna contains an electrically conductive antenna structure on an outer layer of a printed circuit board, the antenna structure has a first resonance frequency. The printed circuit board antenna additionally contains an electrically conductive feed line to the antenna structure and an electrically conductive reference region on the outer layer. The reference region completely encloses the antenna structure with the exception of an insulating feed recess for the feed line and an insulating web recess. The web recess is arranged on the antenna structure face facing away from the feed line, and the reference region has a reference region web on the antenna structure face facing away from the feed line. The reference region web forms a resonator which is capacitively coupled to the antenna structure and has a second resonance frequency. |
