ANTENNA DEVICE, ANTENNA SYSTEM AND METHOD OF OPERATION

摘要

An antenna device (200) according to the invention comprises a dielectric substrate (1) with a front dielectric face (2) and a back dielectric face (3), at least one dipole means (4) printed on said dielectric substrate (1), comprising a first and a second element (5, 6) for radiating and receiving electromagnetic signals, said first element (5) pointing in a first direction and said second element (6) pointing in a second direction opposite to said first direction, and a reflector means (10) associated with the dipole means (4), wherein the printed dipole means (4) defines a symmetry plane (100) perpendicular to the substrate (1), the reflector means (10) has a generally concave shape symmetric to a symmetry plane of the reflector means (10) and the symmetry plane of the reflector means (10) coincides with the symmetry plane (100) of the dipole means (4).
