Patent ID: 8599063

Claim:
An antenna device, comprising: a plane dipole antenna for radiating an electromagnetic wave, the plane dipole antenna being arranged in a first direction and configured such that the radiated electromagnetic wave has its center axis substantially in a plane extending in the first direction; an electromagnetic wave shaping module, arranged forward of the electromagnetic wave radiation source, the electromagnetic wave shaping module extending in the first direction; and a plurality of slot array rows, each slot array row including a plurality of slots arranged in the first direction, and the slot array rows being arranged in a second direction, the second direction being perpendicular to the first direction; the electromagnetic wave shaping module including at least a pair of the slot array rows arranged at positions mutually symmetrical in the second direction with respect to a plane extending in the first direction, said plane including the center axis; where each slot in a topmost slot array row, and each slot in a bottom-most slot array row, is configured to extract a radiated electromagnetic wave from the electromagnetic wave radiation source.
