Abstract

A quadruple polarization antenna apparatus comprising: first dual-polarization antenna element; a second dual-polarization antenna element disposed below the first dual-polarization antenna element so that at least a portion overlaps the first dual-polarization antenna element; and a connecting part configured to connect the first dual-polarization antenna element and the second dual-polarization antenna element.

Claims (19)

1 . A quadruple polarization antenna apparatus comprising:

first dual-polarization antenna element;

a second dual-polarization antenna element disposed below the first dual-polarization antenna element so that at least a portion overlaps the first dual-polarization antenna element; and

a connecting part configured to connect the first dual-polarization antenna element and the second dual-polarization antenna element.

2 . The quadruple polarization antenna apparatus of claim 1 , wherein the first dual-polarization antenna element is formed to have a smaller size than the second dual-polarization antenna element.

3 . The quadruple polarization antenna apparatus of claim 1 , wherein the connecting part constitutes a ground plane of the first dual-polarization antenna element.

4 . The quadruple polarization antenna apparatus of claim 1 , wherein the connecting part is formed in a shape in which a cross-sectional area on a side of the first dual-polarization antenna element is larger than a cross-sectional area on a side of the second dual-polarization antenna element.

5 . The quadruple polarization antenna apparatus of claim 4 , wherein the connecting part is formed in a shape whose cross-sectional area gradually decreases along a direction from the first dual-polarization antenna element to the second dual-polarization antenna element.

6 . The quadruple polarization antenna apparatus of claim 5 , wherein the connecting part is formed in a cone shape.

7 . The quadruple polarization antenna apparatus of claim 1 , wherein the first dual-polarization antenna element and the second dual-polarization antenna element are configured as a patch type.

8 . The quadruple polarization antenna apparatus of claim 1 , wherein the first dual-polarization antenna element includes a dielectric substrate.

9 . The quadruple polarization antenna apparatus of claim 1 , wherein the second dual-polarization antenna element is configured as a ring patch model.

10 . The quadruple polarization antenna apparatus of claim 1 , wherein the second dual-polarization antenna element is formed in a hollow shape.

11 . The quadruple polarization antenna apparatus of claim 1 , wherein the first dual-polarization antenna element is an antenna element for ±45° polarization.

12 . The quadruple polarization antenna apparatus of claim 1 , wherein the second dual-polarization antenna element is an antenna element for V/H polarization.

13 . The quadruple polarization antenna apparatus of claim 1 , further comprising a radiation suppression member disposed to surround the first dual-polarization antenna element.

14 . The quadruple polarization antenna apparatus of claim 1 , wherein a height (h), which is a distance from the second dual-polarization antenna element to the first dual-polarization antenna element, is 0.12λ or more.

15 . A quadruple polarization antenna array comprising a plurality of the quadruple polarization antenna apparatuses of claim 1 arranged in an array,

wherein an interval between the quadruple polarization antenna apparatuses is 0.7λ or more.
