Abstract
The object of the present invention is to achieve an easily mounted antenna device for receiving and/or transmitting circular polarized RF signals in at least one and preferably two frequency bands with a well defined interface towards the circuitry in the hand-held mobile communication device. This is obtained by providing N radiating elements where N is an integer greater than one, a support means arranged to support said radiating elements, a housing, and at least one connection member arranged to be easily connectable to a circuitry on a first printed circuit carrier arranged in said hand-held mobile communication device. Further more, providing at least one phasing network comprising N first ports arranged to be connected to said radiating elements and at least one second port arranged to be connected to said connection member, said phasing network being mounted to said support.
