MULTI POLARIZATION DIPOLE ANTENNA

摘要

Disclosed is a multi-polarization dipole antenna. The dipole antenna includes: a first substrate; a second substrate which is perpendicularly combined to the first substrate; a first dipole radiation device which is formed on the first substrate, and includes a first dipole element connected to a power supply and a second dipole element connected to a ground; a second dipole radiation device which is formed on the second substrate, and includes a third dipole element connected to the power supply and a fourth dipole element connected to the ground; and a plurality of parasitic devices which are formed to be separated from the first dipole element and the fourth dipole element. The antenna, related to this invention, can have wideband characteristics, and reduce a level of a cross-polarized wave ratio in the multi-polarization antenna.
