Dual polarization antenna and dual polarization antenna assembly comprising same

A dual polarization antenna, comprising:

• a base substrate;
• a power feeding unit supported on the base substrate;
• and
• a radiating plate supported on the power feeding unit,
• wherein the first feeding substrate comprises:
• a first insulating substrate supported on the base substrate, and
• a first feed line attached to the first insulating substrate and configured to supply a first reference phase signal to a first point on the radiating plate and to supply to a second point on the radiating plate, a first reverse phase signal having a reverse phase relative to the first reference phase signal, and
• wherein the second feeding substrate comprises:
• a second insulating substrate supported on the base substrate, and
• a second feed line attached to the first insulating substrate and configured to supply a second reference phase signal to a third point on the radiating plate and to supply to a fourth point on the radiating plate, a second reverse phase signal having a reverse phase relative to the second reference phase signal,
• wherein the first feeding substrate and the second feeding substrate each comprise:
• an adhesive tape pattern disposed on each of the first insulating substrate and the second insulating substrate, and
• wherein the first feedline and the second feedline each comprise:
• a metal pattern attached to the adhesive tape pattern,
• wherein the metal pattern further comprises a waterproof adhesion technology (WAT) treatment layer that is disposed on the adhesive tape pattern.
