Abstract (en)

[origin: EP1026774A2] The antenna includes a planar inverted F-antenna with a feeding point and one or several earth connections. The antenna determines with its size the lower emission frequency and has one or several notches or graduations in its lateral direction. One or several geometrical paths are provided which are composed of straight or bent single paths and which extend from the feeding point to another corner provided by the notches, graduations or form changes. Emitted waves are formed with a higher frequency than the predetermined lower frequency. Preferably, a separated earth plate is allocated to the antenna.
