Abstract:
1. A printed circuit board including a surface mounted device antenna with at least one resonant conductor track structure, the printed circuit board comprising a ground metallization configured to substantially surround the antenna, and to connect to one end of the conductor track structure, the antenna comprising: a first supply lead configured to connect one end of a first resonant track structure of the antenna to a ground potential; a second supply lead configured to couple an electromagnetic wave to be emitted into the antenna, which first track structure has a plurality of conductor sections, while the length of the conductor track structure is dimensioned so as to excite a desired first resonant frequency, and paths of the conductor sections and spacings between the conductor sections are configured to excite a first harmonic of the first resonant frequency; and a second resonant track structure, one end of which is connected to the second supply lead and the length of which is configured dimensionally to excite at least one of a desired second resonant frequency and a harmonic of the second resonant frequency.
