Abstract

An electronic device and 3-dimensional antenna structure thereof. The electronic device includes a printed board circuit module and a 3-dimensional antenna comprising a ground plane, and an antenna body having a first portion and a second portion disposed is such manner that one side of the second portion is connected to the first portion and another side of the second portion is connected to the ground plane. A feed line is connected to the first portion, a first regulation plate extends from one side of the first portion, a second regulation plate extends from another side of the first portion, near the printed circuit board and adjacent to the first regulation plate, and a third regulation plate extends upward from the ground plane perpendicular to the axis of the first portion.

Claims

1. A 3-dimensional antenna structure, comprising:

a ground plane;

an antenna body having a first portion and a second portion, wherein one side of the second portion is connected to the first portion and another side of the second portion is connected to the ground plane;

a feed line connected to the antenna body;

a field pattern regulation plate extending from one side of the first portion; and

a polarization regulation plate extending upward from the ground plane perpendicular to the axis of the first portion.

2. The 3-dimensional antenna structure as claimed in claim 1, wherein the feed line is electrically connected to the first portion.

3. The 3-dimensional antenna structure as claimed in claim 1, wherein the first portion, the second portion, and the feed line form an inverted F shape.

4. The 3-dimensional antenna structure as claimed in claim 1, wherein the field pattern regulation plate comprises a first regulation plate extending from one side of the first portion and a second regulation plate extending from another side of the first portion, the second regulation plate adjacent to the first regulation plate.

5. The 3-dimensional antenna structure as claimed in claim 4, wherein the first regulation plate and the second regulation plate are integral with the antenna body.

6. The 3-dimensional antenna structure as claimed in claim 1, wherein the antenna body comprises oxygen-free copper.

7. The 3-dimensional antenna structure as claimed in claim 1, wherein the antenna body is coated with a layer of palladium-nickel alloy.

8. An electronic device, comprising:

a printed board circuit module;

a ground plane;

an antenna body having a first portion and a second portion, wherein one side of the second portion is connected to the first portion and another side of the second portion is connected to the ground plane;

a feed line connected to the first portion;

a first regulation plate extending from one side of the first portion;

a second regulation plate extending from another side of the first portion, near the printed circuit board and adjacent to the first regulation plate; and

a third regulation plate extending upward from the ground plane perpendicular to the axis of the first portion.

9. The electronic device as claimed in claim 8, wherein the first portion, the second portion, and the feed line form an inverted F shape.

10. The electronic device as claimed in claim 8 further comprising a metal shielding element covering the printed circuit board and a guard covering the antenna body, the feed line, the first regulation plate, the second regulation plate and the third regulation plate.

11. The electronic device as claimed in claim 8, wherein the first regulation plate and the second regulation plate are integral with the antenna body.

12. The electronic device as claimed in claim 8, wherein the antenna body comprises oxygen-free copper.

13. The electronic device as claimed in claim 8, wherein the antenna body is coated with a layer of palladium-nickel alloy.
