Patent ID: 7414590

Claim:
An antenna array comprising: first and second separate sheet-shaped supports, wherein each of the first and second sheet-shaped supports is folded along corresponding first and second fold-lines in said first and second sheet-shaped supports, respectively, so as to form through each of said first and second sheet-shaped supports: a first support plane, in each one of the first and second sheet-shaped supports and respectively along said first and second ones of the fold-lines, having a first antenna structure arranged for receiving or emitting electro-magnetic radiation; and a second support plane, in each one of the first and second sheet-shaped supports and adjacent to said first support plane therein and respectively along said first and second ones of the fold-lines, the second support plane in said each one of the first and second sheet-shaped supports being positioned at an angle with respect to the first support plane also in said each one of the first and second sheet-shaped supports, respectively, and having a second antenna structure arranged for receiving or emitting electro-magnetic radiation which differs in at least one property from the electro-magnetic radiation which is received or emitted by the first antenna structure; and wherein the first and second sheet-shaped supports are physically connected to each other at or near the first and second fold-lines.
