Antenna apparatus

1. An antenna apparatus, comprising:

a feed via;

a patch antenna pattern electrically connected to the feed via; and

coupling patterns spaced apart from the patch antenna pattern and spaced apart from each other,

wherein a first coupling pattern, among the coupling patterns, is spaced apart from the patch antenna pattern in a first direction and comprises one or more first protruding portions protruding in the first direction.

2. The antenna apparatus of claim 1 , wherein the one or more first protruding portions protruding protrude at different locations.

3. The antenna apparatus of claim 2 , wherein a width of a gap between adjacent protruding portions among the one or more first protruding portions is less than a width of each of the one or more first protruding portions.

4. The antenna apparatus of claim 1 , wherein a second coupling pattern, among the coupling patterns, is spaced apart from the patch antenna pattern in a second direction different from the first direction and comprises one or more second protruding portions protruding in the second direction, and

wherein the second coupling pattern has an area greater than an area of the first coupling pattern.

5. The antenna apparatus of claim 4 ,

wherein the patch antenna pattern comprises patch antenna patterns, and

wherein the patch antenna patterns are arranged in a row in the second direction.

6. The antenna apparatus of claim 1 , wherein a second coupling pattern, among the coupling patterns, is spaced apart from the patch antenna pattern in a second direction different from the first direction and comprises second protruding portions,

wherein one of the second protruding portions protrudes in the second direction, and another one of the second protruding portions protrudes towards the patch antenna pattern, and

wherein the other one of the second protruding portion protrudes towards the patch antenna portion by a length shorter than a length by which the one of the second protruding portions protrudes in the second direction.

7. The antenna apparatus of claim 1 ,

wherein a second coupling pattern, among the coupling patterns, is spaced apart from the patch antenna pattern in a second direction different from the first direction and comprises one or more second protruding portions protruding in the second direction and one or more other second protruding portions protruding towards the patch antenna pattern, and

wherein the first coupling pattern does not comprise a portion protruding towards the patch antenna pattern.

8. The antenna apparatus of claim 1 , further comprising:

a ground plane having a through-hole through which the feed via penetrates,

wherein a conductive structure is not connected between the coupling patterns and the ground plane.

9. The antenna apparatus of claim 1 , further comprising:

a coupling patch pattern disposed above the patch antenna pattern and spaced apart from the patch antenna pattern,

wherein the coupling patterns are arranged to surround the coupling patch pattern.

10. The antenna apparatus of claim 1 , wherein, in a region including pixels, each of the coupling patterns occupies the pixels by unit of the pixels, each pixel has an area smaller than an area of a smallest coupling pattern among the coupling patterns, and each of the coupling patterns is disposed to occupy portions of the pixels and to not occupy other portions of the pixels.

11. The antenna apparatus of claim 1 , wherein a second coupling pattern, among the coupling patterns, is spaced apart from the patch antenna pattern in a second direction different from the first direction and comprises one or more second protruding portions protruding in the second direction, and

wherein a corner coupling pattern, among the coupling patterns, is disposed between the first coupling pattern and the second coupling pattern.

12. The antenna apparatus of claim 11 , wherein the one or more first protruding portions comprise three or more first protruding portions, the one or more second protruding portions comprise three or more second protruding portions, and the corner pattern comprises three or more third protruding portions protruding in directions in which the corner pattern is spaced apart from the patch antenna pattern.

13. An antenna apparatus, comprising:

a feed via;

a patch antenna pattern electrically connected to the feed via; and

coupling patterns spaced apart from the patch antenna pattern and spaced apart from each other,

wherein, in a region including pixels, each pixel has an area smaller than an area of a smallest coupling pattern among the coupling patterns, and each of the coupling patterns occupies some pixels, among the pixels, and comprises five or more vertices.

14. The antenna apparatus of claim 13 , wherein a width of the some pixels occupied by the coupling patterns is greater than a width of other pixels, among the pixels, that are not occupied by the coupling patterns.

15. The antenna apparatus of claim 13 , further comprising:

a coupling patch pattern disposed above the patch antenna pattern and spaced apart from the patch antenna pattern,

wherein the coupling patch pattern and the coupling patterns are disposed on a same level.

16. The antenna apparatus of claim 15 , wherein a region disposed on a level of the patch antenna pattern and overlapping the coupling patch pattern is formed of a non-conductive medium.

17. The antenna apparatus of claim 13 ,

wherein the patch antenna pattern comprises patch antenna patterns, and

wherein the patch antenna patterns are arranged in a row in one direction.

18. The antenna apparatus of claim 17 , wherein a coupling pattern, among the coupling patterns, spaced apart from the patch antenna patterns in the one direction has an area greater than an area of a coupling pattern, among the coupling patterns, spaced apart from the patch antenna patterns in another direction different from the one direction.
