Abstract

An antenna includes a dielectric substrate, a radiator disposed on one surface of the dielectric substrate, a feeding conductive pattern having one end connected with the radiator and the other end connected with an external feed line, a first slot disposed in the feeding conductive pattern, a ground plane disposed on the other surface of the dielectric substrate, and a second slot disposed on the ground plane.

Claims

1. An antenna comprising:

a dielectric substrate;

a radiator disposed on one surface of the dielectric substrate;

a feeding conductive pattern having one end connected with the radiator and the other end connected with an external feed line;

a first slot disposed in the feeding conductive pattern;

a ground plane disposed on the other surface of the dielectric substrate; and

a second slot disposed in the ground plane.

2. The antenna of claim 1, wherein the radiator has an ultra wide band (UWB) frequency band characteristic.

3. The antenna of claim 2, wherein the radiator is a patch type radiator.

4. The antenna of claim 1, wherein the first slot separates the feeding conductive pattern into a plurality of portions.

5. The antenna of claim 1, wherein the first slot has a meander line shape.

6. The antenna of claim 1, wherein the second slot overlaps the feeding conductive pattern at least in part.

7. The antenna of claim 6, wherein the second slot is disposed at a location corresponding to a location at which the first slot is disposed.

8. The antenna of claim 6, wherein the second slot has a symmetrical shape.

9. The antenna of claim 8, wherein a central line of the symmetrical shape of the second slot faces the feeding conductive pattern.

10. The antenna of claim 1, wherein the second slot has a dumbbell shape.

11. The antenna of claim 1, further comprising a stub disposed between the radiator and the feeding conductive pattern.
