ANTENNA ARRAY FOR TRANSMITTING AND/OR FOR RECEIVING RADIO FREQUENCY SIGNALS, ACCESS NETWORK NODE AND VEHICLE THEREOF

The embodiments of the invention relate to antenna array (AA1) for transmitting and/or for receiving radio frequency signals. The antenna array (AA1) 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.
