Mechanical/Electrical Hybrid 2-Dimensional Beam Scanning Cylindrical Dielectric Lens Antenna

A hybrid 2-dimensional beam scanning cylindrical lens antenna by combining a mechanical lens slide and a linear phased array is presented. The proposed antenna scans the main beam mechanically within the lens displacement plane by sliding the lens in one dimension. The proposed antenna also scans the beam electrically by a phased array of primary radiators arranged orthogonal to the mechanical beam scanning plane. The 2-dimensional beam scanning performance of the proposed antenna has been demonstrated through EM simulation; the proposed antenna capable of 2-dimensional beam scanning over a spherical angular range of ±10°.
