Abstract

An antenna device for radio telephone based on a printed circuit board antenna or a strip conductor antenna 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 electromagnetic radiation and the parasitic interference of the telephone caused by the user is reduced. To this end, the strip conductor carrier is cut around strip conductors used as the antenna up to a section used for the connection of the strip conductor used as the antenna to the other strip conductors of the strip conductor carrier. Furthermore, at least when the strip conductor carrier is mounted in the radio telephone, the cut-out regions of the strip conductor carrier, carrying the strip conductor used as the antenna is deflected out of the plane of the other regions of the strip conductor carrier.
