The object of the present invention is to achieve an easily mounted antenna device (104) 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 (103) 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 (106) arranged to support said radiating elements, a housing (105), and at least one connection member (110, 111) arranged to be easily connectable to a circuitry (103) on a first printed circuit carrier (102) arranged in said hand-held mobile communication device. Furthermore, providing at least one phasing network (112) 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.

L'invention se rapporte à un dispositif à antenne (104) facile à assembler, conçu pour recevoir et/ou émettre des signaux R.F. à polarisation circulaire dans au moins une et de préférence deux bandes de fréquences, et muni d'une interface bien définie avec les circuits (103) présents dans le dispositif de communication mobile à main. Pour ce faire, on met en oeuvre N éléments rayonnants, N étant un nombre entier supérieur ou égal à un, un organe de support (106) agencé de manière à supporter lesdits éléments rayonnants, un boîtier (105) et au moins un élément de connexion (110, 111) conçu pour être facilement connecté aux circuits (103) sur un premier support de circuit imprimé (102) disposé dans ledit dispositif de communication mobile à main. En outre, on met en oeuvre au moins un réseau de mise en phase (112) comportant N premiers points d'accès susceptibles d'être reliés auxdits éléments rayonnants et au moins un second point d'accès conçu pour être connecté audit élément de connexion, ledit réseau de mise en phase étant monté sur ledit support.
