The present disclosure further seeks to provide a dual-polarized antenna capable of reducing the number of contact points and the complexity of signal wiring in manufacturing processes while improving the degree of inter-polarization isolation and the distinguishability between cross polarized waves or cross-polarization distinguishability.

It will be apparent to those skilled in the art from the following description that the subject matter to which the present disclosure is directed is not limited to the challenges set forth above but encompasses other unmentioned technical tasks to be addressed.

At least one aspect of the present disclosure provides a dual-polarized antenna including a base board, a feeding unit supported on the base board, and a radiation plate supported on the feeding unit.

The feeding unit includes a first feeding board and a second feeding board arranged to cross each other on the base board.

The first feeding board includes 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 includes 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.
