ABSTRACT:
An antenna device has a sheet-shaped support which is folded along various fold-lines. The support includes a first support plane adjacent to one of the fold-lines and a second support place adjacent to the same fold-line. The first and second support places have first and second antenna structures, respectively, each arranged for receiving or emitting electro-magnetic radiation. The second support plane is positioned at an angle with respect to the first support plane. The second antenna structure is sensitive to electro-magnetic radiation which differs in, e.g., polarization from that of electro-magnetic radiation to which the first antenna structure is sensitive.
