ANTENNA DEVICE FOR RADIO TELEPHONES

2007
The aim of the invention is to technically improve an antenna device for radio telephones, based on a printed circuit board antenna or a strip conductor antenna, in such a way that it is economical and simple to produce and has a high efficiency, but nevertheless ensures that the user of the radio telephone is less exposed to the effects of ...
