Abstract
(EN)
The embodiments of the invention relate to antenna array (AAl ) for transmitting and/or for receiving radio frequency signals. The antenna array (AAl ) contains a first antenna element (AE1 ) and a second antenna element (AE2a) forming a first basic arrangement (BA1 ). The first antenna element (AE1 ) has a first substantially flat form and is adapted to excite within a first excitation area (EA1 ) a first electromagnetic field with a first polarization direction (PD1 ) and a second electromagnetic field with a second polarization direction (PD2) different to the first polarization direction (PD1 ). The second antenna element (AE2a) also has a second substantially flat form. The second antenna element (AE2a) is arranged adjacent to the first antenna element (AE1 ) and is adapted to excite at least a third electromagnetic field with a third polarization direction (PD3) non-parallel to the first polarization direction (PD1 ) and non- parallel to the second polarization direction (PD2) within a second excitation area (EA2) arranged non- parallel to the first excitation area (EA1 ) and facing towards the first excitation area (EA1 ). The embodiments further relate to an access network node, which contains the antenna array and to a vehicle, which contains the access network node.

Les modes de réalisation de l'invention portent sur un réseau d’antennes (AAl) permettant d'émettre et/ou de recevoir des signaux à radiofréquence. Le réseau d’antennes (AAl) contient un premier élément d'antenne (AE1) et un second élément d'antenne (AE2a) formant un premier agencement de base (BA1). Le premier élément d'antenne (AE1) a une première forme sensiblement plate et permet d'exciter dans une première zone d'excitation (EA1) un premier champ électromagnétique avec une première direction de polarisation (PD1) et un deuxième champ électromagnétique avec une deuxième direction de polarisation (PD2) différente de la première direction de polarisation (PD1). Le second élément d'antenne (AE2a) a aussi une seconde forme sensiblement plate. Le second élément d'antenne (AE2a) est agencé de manière adjacente au premier élément d'antenne (AE1) et permet d'exciter au moins un troisième champ électromagnétique avec une troisième direction de polarisation (PD3) non parallèle à la première direction de polarisation (PD1) et non parallèle à la deuxième direction de polarisation (PD2) dans une seconde zone d'excitation (EA2) agencée non parallèlement à la première zone d'excitation (EA1) et faisant face à la première zone d'excitation (EA1). Les modes de réalisation portent en outre sur un nœud d'accès réseau, lequel contient le réseau d’antennes, et sur un véhicule, lequel contient le nœud d'accès réseau.
