Claim 5:
6. The device of claim 2, wherein at least one antenna comprises, within a multi-layer printed circuit board, at least two EBG structures and a substrate integrated waveguide (SIW) waveguide, formed between the at least two EBG structures,
wherein the conductive portions of adjacent cells of the EBG structure included in the antenna are electrically connected to each other within the conductive layers of the printed circuit board to form the upper base and the lower base of the SIW waveguide, and
the conductive portions of adjacent cells of the EBG structures included in the antenna are not electrically connected to each other within outermost conductive layers of the printed circuit board.
