PARASITIC ELEMENTS FOR ISOLATING ORTHOGONAL SIGNAL PATHS AND GENERATING ADDITIONAL RESONANCE IN A DUAL-POLARIZED ANTENNA

摘要

An antenna system may include a dual-polarized antenna element having a first dipole and a second dipole in a same lateral plane, the first dipole having a first and a second dipole arm, the second dipole comprising a third and a fourth dipole arm, the first dipole being co-located with the second dipole, and the first dipole having an orthogonal polarization to the second dipole. The antenna system may further include parasitic elements, each comprising at least two branches, the at least two branches including a first branch and a second branch oriented at an angle and forming an apex. A first branch of a first parasitic element may be positioned at a first coupling distance parallel to the first dipole arm of the first dipole, and a second branch may be positioned at a second coupling distance parallel to the third dipole arm of the second dipole.
