Abstract

An antenna module includes a support and an antenna. The support includes an upper surface and has a through hole defined in a middle of the upper surface. The antenna includes a feed unit, a first radiator unit, and a second radiator unit. One end of the feed unit is positioned on the upper surface. The other end of the feed unit passes through the through hole, and extends and attaches to a surface opposite to the upper surface. The first radiator unit and the second radiator unit are both connected to the end of the feed unit positioned on the upper surface, and both extend away from the feed unit.

Claims

1. An antenna module, comprising:

a support including an upper surface and having a through hole defined on a middle position of the upper surface; and

an antenna including a feed unit, a first radiator unit, and a second radiator unit;

wherein one end of the feed unit is positioned in the upper surface, the other end of the feed unit passes through the through hole, and extends and attaches to a surface opposite to the upper surface;

the first radiator unit and the second radiator unit are both connected to the end of the feed unit positioned in the upper surface, and both extend away from the feed unit.

2. The antenna module as claimed in claim 1, wherein the first radiator unit and the second radiator unit generate low frequency signals and high frequency signals, respectively.

3. The antenna module as claimed in claim 1, wherein the first radiator unit is longer than the second radiator unit.

4. The antenna module as claimed in claim 1, wherein the antenna is a monopole antenna.

5. The antenna module as claimed in claim 1, wherein the support further includes a first sidewall, a second sidewall opposite to the second sidewall, and a third sidewall connected both the first sidewall and the second sidewall, the first sidewall, the second sidewall, and the third sidewall are approximately perpendicular to the upper surface, and cooperatively form a receiving space for receiving electronic components.

6. The antenna module as claimed in claim 5, wherein the first radiator unit is positioned on the top surface, the second sidewall, and the third sidewall.

7. The antenna module as claimed in claim 6, wherein a communication performance of the first radiator unit can be adjusted by changing a width of an end of the first radiator unit.

8. The antenna module as claimed in claim 5, wherein the second radiator unit is positioned on the upper surface and the first sidewall.

9. The antenna module as claimed in claim 1, further including a ground unit and a resonance unit, one end of the feed unit is positioned in the upper surface, the other end of the feed unit passes through the through hole, and extends and attaches to the surface opposite to the upper surface, an end of the resonance unit is connected to the ground unit, the other end of the resonance unit extends away from the ground unit.

10. The antenna module as claimed in claim 9, wherein the resonance unit generates corresponding resonance signals.

11. The antenna module as claimed in claim 9, wherein the second radiator unit is longer than the resonance unit.

12. The antenna module as claimed in claim 9, wherein the resonance unit is positioned on the upper surface, the resonance unit and the second radiator unit are set at a same side of the first radiator unit, the end of the resonance unit connected to the ground unit is parallel to an end of the second radiator, and the other end of the resonance unit extends away from the second unit, thereby forming a slot.

13. The antenna module as claimed in claim 12, wherein the electronic length of the antenna module can be tuned to a particular desired frequency band performance by varying the size of the slot.
