Abstract

Disclosed is an antenna device for transceiving a wireless signal with an insert-molded antenna pattern embedded inside a casing of an electronic device. The insert-molded antenna pattern is connected to an antenna module of a motherboard of the electronic device in order to feed the wireless signal transceived by the insert-molded antenna pattern through an antenna signal feeding line connected to the insert-molded antenna pattern and the antenna module, or by an antenna coupling element coupled with the insert-molded antenna pattern.

Claims

1. An antenna device, comprising:

a substrate having a first surface and a second surface;

an insert-molded antenna pattern embedded in the substrate and formed by an insert-molding process for transceiving a wireless signal of a predetermined radiation frequency, wherein the substrate comprises at least one through hole communicating the second surface and a bottom surface of the insert-molded antenna pattern;

a signal conducting member with a first end connecting to the insert-molded antenna pattern and a second end extended to the second surface of the substrate, wherein the signal conducting member comprises a coating of conductive material coated on an interior wall of the through hole; and

an antenna signal feeding line connecting to the signal conducting member for feeding the wireless signal transceived by the insert-molded antenna pattern through the signal conducting member, wherein the insert-molded antenna pattern is electrically connected to an antenna module of an electronic device through the signal conducting member and the antenna signal feeding line.

2. The antenna device as claimed in claim 1, wherein the insert-molded antenna pattern has a top surface exposed to the first surface of the substrate.

3. The antenna device as claimed in claim 1, wherein the insert-molded antenna pattern has a top surface adjacent to the first surface of the substrate.

4. The antenna device as claimed in claim 2, wherein the through hole communicates the first surface and the second surface of the substrate.

5. The antenna device as claimed in claim 1, wherein the substrate is made of plastic material.

6. The antenna device as claimed in claim 1, wherein the substrate is a casing of an electronic device.
