Abstract

An antenna includes a first antenna portion, a second antenna portion, a third antenna portion, a feed portion, and a ground portion. The first antenna portion perpendicularly connects to the feed portion and the ground portion. The second antenna portion connects to the first antenna portion. The third antenna portion connects to the feed portion. The first antenna portion and the second antenna portion are both located on a plane perpendicular to the feed portion. The feed portion, the ground portion, and the third antenna portion are coplanar.

Claims

1. An antenna, comprising:

a feed portion;

a ground portion;

a first antenna portion perpendicularly connecting to the feed portion and the ground portion;

a second antenna portion connecting to the first antenna portion; and

a third antenna portion connecting to the feed portion;

wherein the first antenna portion and the second antenna portion are both located on a plane perpendicular to the feed portion; and

wherein the feed portion, the ground portion, and the third antenna portion are coplanar.

2. The antenna of claim 1, wherein the feed portion and the ground portion are parallel.

3. The antenna of claim 1, wherein the first antenna portion comprises:

two parallel long edges; and

two short edges perpendicular to the two long edges.

4. The antenna of claim 3, wherein the second antenna portion comprises:

a connection section connecting to one of the two long edges near one of the two short edges; and

an extension section connecting to the connection section.

5. The antenna of claim 1, wherein the third antenna portion comprises a main body, a capacitor, and an inductor;

wherein the main body connects to the feed portion through the inductor, and connects to ground through the capacitor.

6. The antenna of claim 5, wherein the main body is a planar inverted-F antenna (PIFA).

7. The antenna of claim 6, wherein the third antenna portion further comprises:

a first radiating section connecting to the feed portion through the inductor;

a second radiating section perpendicularly connecting to one end of the first radiating section away from the feed portion; and

a third radiating section disposed between the second radiating section and the feed portion.

8. The antenna of claim 7, wherein one end of the third radiating section perpendicularly connects to the first radiating section, and the other end of the third radiating section connects to ground through the capacitor.
