Abstract

An antenna for an electronic device is disclosed that can reduce or prevent problems such as a shock hazard and/or an Electrostatic Discharge (ESD) issue, particularly in the case when device are subjected to impact such as being dropped. The antenna includes a radiator; an antenna clip connected with a metallic housing of the electronic device; a capacitor includes a part of the antenna clip; and a feeding part and a ground for operating the antenna.

Claims

1. An antenna for an electronic device comprising:

a radiator;

an antenna clip connected to a metallic housing of the electronic device, in which a part of the antenna clip comprises at least a first conductor of a capacitor;

a feeding part connected with a first portion of the radiator; and

a ground connected with a second portion of the radiator and the capacitor,

wherein the capacitor further includes a second conductor arranged in parallel with the part of the antenna clip, and a dielectric between the first conductor and the second conductor, and

wherein at least a part of the metallic housing comprises the second conductor.

2. The antenna of claim 1, wherein the radiator comprises at least a part of the metallic housing.

3. The antenna of claim 1, wherein the dielectric includes an adhesive that affixes positions of the first conductor and the second conductor in parallel with each other.

4. The antenna of claim 3, wherein the antenna clip is connected to the feeding part and/or the ground through the second conductor of the capacitor.

5. The antenna of claim 4, further comprising a printed circuit board that comprises the feeding part and the ground, and wherein the second conductor is connected to the printed circuit board.

6. The antenna of claim 3, wherein the antenna clip is connected to the metallic housing through the second conductor.

7. The antenna of claim 1, wherein a size of an area of the second conductor and a distance between the first conductor and the second conductor are based on providing a value of capacitance that blocks a direct current (DC) component.

8. The antenna of claim 1, wherein a value of a dielectric constant of the dielectric is based on providing a value of capacitance that blocks a DC component.

9. The antenna of claim 3, wherein a thickness of the dielectric is based on providing a value of capacitance that blocks a DC component.

10. The antenna of claim 1, further comprising an inductor in series with the capacitor.

11. The antenna of claim 1, further comprising an inductor in parallel with the capacitor.

12. An antenna for an electronic device comprising:

a metallic housing;

a radiator comprising at least a part of the metallic housing;

an antenna clip connected with the metallic housing;

a direct current (DC) blocking member comprising at least a part of the antenna clip; and

a feeding part connected with a first portion of the radiator and a ground connected with a second portion of the radiator for operating the antenna,

wherein the DC blocking member includes a conductor arranged in parallel with the part of the antenna clip, and a dielectric between the conductor and the part of the antenna clip, and

wherein at least a part of the metallic housing comprises the conductor.

13. The antenna of claim 12, wherein the DC blocking member includes a capacitive component to block a flow of a direct current.

14. The antenna of claim 12, wherein the DC blocking member includes a capacitive component to block a flow of a direct current together with at least a part of the radiator that is arranged to correspond to the DC blocking member.

15. The antenna of claim 12, further comprising an inductor in series with the DC blocking member.

16. The antenna of claim 12, further comprising an inductor in parallel with the DC blocking member.
