Abstract

A dual polarization antenna is disclosed in at least one embodiment of the present disclosure, including 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 includes 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 includes 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.

Claims (27)

1 . 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.

2 . The dual polarization antenna of claim 1 , wherein the adhesive tape pattern on the first insulating substrate, the adhesive tape pattern on the second insulating substrate, and the WAT treatment layer of the metal pattern are fixed through a heat curing process.

3 . The dual polarization antenna of claim 1 , wherein the first feeding substrate and the second feeding substrate are vertically upright on the base substrate, and the first feeding substrate and the second feeding substrate have respective midsections that intersect perpendicular to each other.

4 . The dual polarization antenna of claim 1 , wherein the first feeding substrate is disposed parallel to a straight line connecting the first point and the second point, and the second feeding substrate is disposed parallel to a straight line connecting the third point and the fourth point.

5 . The dual polarization antenna of claim 1 , wherein

the radiating plate is square,

the first point, the second point, the third point, and the fourth point are adjacent to four vertices of the radiating plate, and

the radiating plate has a diagonal length that is equal to a half wavelength of a center frequency of a frequency in use.

6 . The dual polarization antenna of claim 1 , wherein the first feed line is connected to a signal line of the base substrate through one solder joint, and the second feed line is connected to another signal line of the base substrate through another solder joint.

7 . A dual polarization antenna assembly, comprising:

a casing;

one or more of the dual polarization antenna according to claim 1 disposed on the casing; and

a radome configured to cover the one or more of the dual polarization antenna.
