Abstract

An antenna module, which minimizes a space, in an electronic apparatus set, occupied thereby without changing characteristics thereof, improves a degree of freedom of the installation structure thereof to increase the space utilization of the set, and achieves miniaturization and multi-functionality of electronic apparatuses, and an electronic apparatus having the antenna module. The antenna module includes a PCB (printed circuit board) made of nonconductive material having flexibility; an antenna element mounted at a designated position of the upper surface of the PCB; a ground line formed on the PCB so that the ground line is connected to a ground terminal of the antenna element, and provided with a joint portion formed at one end thereof; a feeder line formed on the PCB so that the feeder line is connected to a signal terminal of the antenna element, and provided with a joint portion formed at one end thereof; and a passive line, having a designated length, formed on the PCB in parallel with the feeder line. The joint portions of the ground line and the feeder line are bonded to designated positions of a set of the wireless electronic apparatus, and a portion of the antenna module having the antenna element mounted on the PCB is located outside the set.

Claims

1. An antenna module comprising:

a PCB (printed circuit board) made of nonconductive material having flexibility;

an antenna element mounted at a designated position of the upper surface of the PCB;

a ground line formed on the PCB so that the ground line is connected to a ground terminal of the antenna element, and provided with a joint portion formed at one end thereof;

a feeder line formed on the PCB so that the feeder line is connected to a signal terminal of the antenna element, and provided with a joint portion formed at one end thereof; and

a passive line, having a designated length, formed on the PCB in parallel with the feeder line.

2. The antenna module according to claim 1, further comprising a fixing board made of nonconductive material having a designated degree of hardness, and attached to the lower surface of the PCB, on which the antenna element is mounted, for supporting the antenna element.

3. The antenna module according to claim 1,

wherein the PCB has a single-layered structure made of one selected from the group consisting of reversible material, including polymer and flexible metal, and irreversible material, including polyimide, polyester, and glass epoxy, or a multi-layered structure including a plurality of sheets made of one or more selected from the above group and attached by an organic bonding agent.

4. The antenna module as set forth in claim 1,

Wherein the antenna element is mounted on the upper surface of the PCB by a die-bonding method.

5. A wireless electronic apparatus comprising:

a set of a plurality of elements constituting a designated circuit; and

an antenna module including;

a PCB (printed circuit board) made of material having flexibility;

an antenna element mounted at a designated position of the upper surface of the PCB;

a ground line formed on the PCB so that the ground line is connected to a ground terminal of the antenna element, and provided with a joint portion formed at one end thereof;

a feeder line formed on the PCB so that the feeder line is connected to a signal terminal of the antenna element, and provided with a joint portion formed at one end thereof; and

a passive line formed on the PCB in parallel with the feeder line,

wherein the joint portions of the ground line and the feeder line are bonded to designated positions of the set, and a portion of the antenna module having the antenna element mounted on the PCB is located outside the set.

6. The wireless electronic apparatus as set forth in claim 5,

wherein the joint portions of the ground line and the feeder line are connected to an outer edge of the upper surface of the set.

7. The wireless electronic apparatus as set forth in claim 6, wherein:

a side wall having a designated size is formed at the side surface of the set; and

the portion of the antenna module having the antenna element is attached to the sidewall.

8. The wireless electronic apparatus as set forth in claim 6, wherein:

a sidewall in a designated size, including a protruded fixing pin, is formed at the side surface of the set;

a fixing hole is formed at a position of the antenna module corresponding to the fixing pin; and

the antenna module is fixed to the sidewall by inserting the fixing pin into the fixing hole.
