Antenna and antenna module including the antenna

1. An antenna comprising:

feed pads;

a radiating portion disposed on one side of the feed pads and spaced apart from the feed pads, the radiating portion being constituted by a single conductor plate;

a ground part disposed on an opposite side of the feed pads from the radiating portion; and

a plurality of dummy patterns disposed on a same level as the feed pads,

wherein the plurality of dummy patterns are spaced from each other,

wherein the radiating portion has a size covering the entirety of the feed pads and dummy patterns, and

wherein edges of the dummy patterns are disposed inside of edges of the radiating portion in a top view.

2. The antenna of claim 1 , wherein each of the dummy patterns comprises a conductive pad disposed between the feed pads.

3. The antenna of claim 2 , wherein the conductive pad of the dummy patterns faces the radiating portion.

4. The antenna of claim 3 , wherein the entire conductive pad of the dummy patterns faces the radiating portion.

5. The antenna of claim 2 , wherein the conductive pad of the dummy patterns is disposed surrounding the feed pads on a same layer as the feed pads and facing the radiating portion.

6. An antenna module comprising:

the antenna of claim 1 ; and

an additional antenna;

wherein the plurality of dummy patterns are disposed between the antenna of claim 1 and the additional antenna, and

wherein the antenna of claim 1 and the additional antenna are configured to operate as an array antenna.

7. The antenna of claim 1 , wherein the feed pads are disposed so that all portions of the feed pads face the radiating portion.

8. The antenna of claim 7 , wherein the feed pads comprise a first feed pad disposed extending in a first direction and a second feed pad disposed extending in a second direction different from the first direction and spaced apart from each other.

9. The antenna of claim 8 , wherein the first direction and the second direction are 90 degrees from each other on the same level.

10. The antenna of claim 8 , further comprising:

a first via having a first end coupled to the first feed pad; and

a second via having a first end coupled to the second feed pad.

11. The antenna of claim 10 , wherein the first via and the second via are biased from the center of the radiating portion.

12. The antenna of claim 10 , further comprising a first feed pattern and a second feed pattern disposed on an opposite side of the ground part from the first feed pad and the second feed pad and spaced apart from the ground part;

wherein the first via and the second via penetrate through the ground part;

a second end of the first via is connected to the first feed pattern; and

a second end of the second via is connected to the second feed pattern.

13. The antenna of claim 7 , wherein each of the feed pads has a rectangular shape.

14. The antenna of claim 13 , wherein the radiating portion has a rectangular shape;

a length of each of the feed pads is 40% or less of a length of the radiating portion; and

a width of each of the feed pads is 30% or less of a width of the radiating portion.

15. The antenna of claim 7 , wherein a radiating frequency of the antenna is determined by a combination of a length of one of the feed pads and a length of the radiating portion; and

an impedance of the antenna is determined by either one or both of a position of the one feed pad and an area of the one feed pad.

16. The antenna of claim 7 , wherein the feed pads comprise four feed pads disposed in four directions relative to a central point between the four feed pads to enable the antenna to receive a signal having a dual polarization.

17. An antenna module comprising:

the antenna of claim 1 ; and

a signal processing element electrically connected to the feed pads and configured to transmit and receive a signal via the antenna.

18. The antenna of claim 1 , wherein the ground part comprises a larger area than the feed pads, and a larger area than the radiating portion.
