1. A dual-polarized antenna comprising:
a base substrate;
a feed unit supported on the base substrate and comprising a first feed substrate and a second feed substrate disposed to cross each other; and
a radiation plate supported on the feed unit,
wherein the first feed substrate comprises a first feed line configured to supply a first region with a first reference-phase signal in a first direction of the radiation plate and to supply a second region sequential to the first region with a first anti-phase signal having a phase opposite to a phase of the first reference-phase signal according to a shift feed method, and
the second feed substrate comprises a second feed line configured to supply a third region with a second reference-phase signal in a second direction of the radiation plate and to supply a fourth region sequential to the third region with a second anti-phase signal having a phase opposite to a phase of the second reference-phase signal according to the shift feed method,
wherein each of the first feed line and the second feed line is implemented so that sequential feeds having a predetermined time difference are performed in an identical direction on the radiation plate according to the shift feed method.
