Abstract (en)

[origin: WO2020212153A1] The invention relates to a printed circuit board antenna (100). The printed circuit board antenna (100) comprises an electrically conductive antenna structure (113) on an outer layer (110) of a printed circuit board (101), said antenna structure (113) having a first resonance frequency. The printed circuit board antenna (100) additionally comprises an electrically conductive feed line (115) to the antenna structure (113) and an electrically conductive reference region (111, 141) on the outer layer (110). The reference region (111, 141) completely encloses the antenna structure (113) with the exception of an insulating feed recess (117) for the feed line (115) and an insulating web recess (142). The web recess (142) is arranged on the antenna structure (113) face facing away from the feed line (115), and the reference region (111, 141) has a reference region web (143) on the antenna structure (113) face facing away from the feed line (115), said reference region web forming a resonator which is capacitively coupled to the antenna structure (113) and has a second resonance frequency.
