Dual polarized antenna and antenna array
The preset invention relates to a dual polarized antenna and an antenna array and, more particularly, to a dual polarized antenna comprising: a top portion having a radiation patch; a bottom portion forming a probe; and side portions formed along the outer peripheral edge of the top portion so as to have a predetermined height, wherein the side portions include a cup-shaped aluminum structure, and the top portion, the bottom portion, and the side portions are formed in an integrated form.
1. A dual polarized antenna comprising:
a top portion having a radiation patch;
a bottom portion forming a probe; and
a side portion formed to have a predetermined height along an outer peripheral surface of the top portion,
wherein the side portion comprises a cup-shaped aluminum structure,
wherein the top portion, the bottom portion and the side portion are formed in an integrated form.
2. The dual polarized antenna of claim 1 , wherein the bottom portion has a rectangular shape,
wherein the probe is formed from each corner of the bottom portion of the rectangular shape to face a center of the bottom portion.
3. The dual polarized antenna of claim 1 , wherein the side portion further comprises a shielding wall portion extending along an outer peripheral surface of the bottom portion so as to have a predetermined angle with respect to the top portion,
wherein the aluminum structure is formed on the shielding wall portion.
4. The dual polarized antenna of claim 1 , wherein the aluminum structure is formed to have a height less than or equal to a height of antenna element.
5. The dual polarized antenna of claim 1 , wherein an area of the radiation patch is equal to or smaller than an area of the top portion,
wherein the radiation patch has a shape of one of a rectangle, a rhombus, a circle, a triangle, and an octagon.
6. The dual polarized antenna of claim 1 , wherein the aluminum structure is formed by one of a first method of metal plating, a second method of surface processing through a laser, and a third method of fusing a separate metal structure.
7. The dual polarized antenna of claim 1 , wherein the probe has an ‘L’ shape.
8. The dual polarized antenna of claim 1 , wherein the aluminum structure is formed in a sawtooth shape or a slot shape.
9. A dual polarized antenna array comprising a plurality of the dual polarized antennas of claim 1 arranged in an array form on a plane,
wherein a distance between the dual polarized antennas is greater than or equal to 0.5 lamda.
