1. A phased array antenna comprising:
a transmission unit of a first layer including a plurality of first plates having a polygonal profile;
a reception unit of a second layer including a plurality of second plates having a polygonal profile, the reception unit being spaced apart from the transmission unit in a first direction;
an isolation unit of a third layer including a plurality of third plates having a polygonal profile, arranged between the transmission unit and the reception unit, and including a plurality of protruding walls; and
a circuit unit arranged within an internal space defined by the transmission unit and the reception unit,
wherein the plurality of first plates are arranged as sides of a regular polygon so that the plurality of first plates form a regular polygon,
the plurality of second plates are arranged as sides a regular polygon so that the plurality of second plates form a regular polygon, and
the plurality of third plates are arranged as sides a regular polygon so that the plurality of third plates form a regular polygon,
wherein the first plate, the second plate and the third plate are arranged on a same vertical plane,
wherein each of the protruding walls is protruded from the third plate on the vertical plane and is extended from one end to another end of the third plate in a second direction so that a cross section of the each of the protruding walls is rectangular in a plane view.
