Dual polarized antenna and dual polarized antenna assembly comprising same

A dual-polarized antenna, comprising:

• a base board;
• a feeding unit supported on the base board;
• and
• a radiation plate supported on the feeding unit,
• wherein the feeding unit comprises a first feeding board and a second feeding board arranged to cross each other on the base board,
• the first feeding board comprises a first feed line configured to supply a first reference-phase signal to a first point on the radiation plate and to supply a first antiphase signal having an antiphase relative to the first reference-phase signal to a second point on the radiation plate,
• the second feeding board comprises a second feed line configured to supply a second reference-phase signal to a third point on the radiation plate and to supply a second antiphase signal having an antiphase relative to the second reference-phase signal to a fourth point on the radiation plate,
• the first feed line comprises a singularity of a first reference-phase coupling electrode configured to be disposed adjacent to one short side of the first feeding board and to be extended from the one short side of the first feeding board toward the other short side of the first feeding board, and a singularity of a first antiphase coupling electrode configured to be disposed adjacent to the other short side of the first feeding board and to be extended from the other short side of the first feeding board toward the one short side of the first feeding board,
• the second feed line comprises a singularity of a second reference-phase coupling electrode configured to be disposed adjacent to one short side of the second feeding board and to be extended from the one short side of the second feeding board toward the other short side of the second feeding board, and a singularity of a second antiphase coupling electrode configured to be disposed adjacent to the other short side of the second feeding board and to be extended from the other short side of the second feeding board toward the one short side of the second feeding board.
