Abstract

A mobile terminal, comprising of a terminal body having a front surface, a rear surface, and side surfaces extending from end portions of the rear surface toward the front surface, the terminal body being made of a metal, a lower module coupled to a lower end of the terminal body and externally exposed to operate as a radiator of an antenna apparatus and a non-metal member interposed between the terminal body and the lower module and forming a slot by spacing the terminal body and the lower module apart from each other, and wherein the antenna apparatus comprises first and second antenna resonating different frequency bands wherein the first antenna and the second antenna comprise a first feeder and a second feeder, respectively, connected to a main printed circuit board provided in the terminal body and generating the electric fields on the first slot and the second slot, respectively, and wherein the lower module comprises first and second member and a connecting portion connecting end portions of the first and second members each other, and wherein the first member is exposed to the front surface of the terminal body, the second member is exposed to the rear surface of the terminal body, and wherein the connecting portion, the first and second members are made of a metal.

First claim

What is claimed is:

1. A mobile terminal, comprising:
a terminal body having a front surface, a rear surface, and side surfaces extending from end portions of the rear surface toward the front surface, the terminal body being made of a metal;
a lower module coupled to a lower end of the terminal body and externally exposed to operate as a radiator of an antenna apparatus; and
a non-metal member interposed between the terminal body and the lower module and forming a slot by spacing the terminal body and the lower module apart from each other, and
wherein the antenna apparatus comprises first and second antenna resonating different frequency bands,
wherein the first antenna and the second antenna comprise a first feeder and a second feeder, respectively, connected to a main printed circuit board provided in the terminal body and generating the electric fields on the first slot and the second slot, respectively,
wherein the lower module comprises first and second member and a connecting portion connecting end portions of the first and second members each other,
wherein the first member is exposed to the front surface of the terminal body, the second member is exposed to the rear surface of the terminal body,
wherein the connecting portion, the first and second members are made of a metal,
wherein the first feeder and the second feeder are connected to an inner side of the first member or the second member,
wherein the mobile terminal further comprises a first stub disposed at the first slot, the first stub comprising one side connected to the lower module and another side forming an open end, and
wherein the first stub is configured to implement a first resonant frequency of a first frequency band.

2. The mobile terminal of claim 1 , wherein at least one of the first feeder and the second feeder is provided with a feeder extending portion disposed at a position overlapped by the non-metal member.

3. The mobile terminal of claim 2 , wherein the feeder extending portion is located at the first slot or the second slot.

4. The mobile terminal of claim 1 , further comprising a second stub disposed on the second slot, and having one side connected to the lower module and another side forming an open end,
wherein the second stub is configured to implement a second resonant frequency of the second frequency band.

5. The mobile terminal of claim 1 , wherein the first member is electrically connected to the connecting portion via a clip member.

6. The mobile terminal of claim 1 , further comprising:
a dividing member crossing the non-metal member, and dividing an area where the terminal body and the lower module are electrically connected and generate an electric field accordingly, the dividing member dividing the slot into first and second slots, and
wherein the dividing member is comprised of a metal strip with a predetermined area or is comprised of a plurality of fine cables.

7. The mobile terminal of claim 1 , wherein the terminal body comprises an intermediate frame made of a metal, and
wherein an electric field is generated between the intermediate frame and the lower module.

8. The mobile terminal of claim 1 , wherein a length of the first slot extending from the dividing member to a first opening at the open side of the first slot is ¼ of a wavelength (λ) corresponding to a center frequency of the first frequency band.

9. The mobile terminal of claim 1 , wherein a length of the second slot extending from the dividing member to a second opening at the open side of the second slot is ¼ of a wavelength (λ) corresponding to a center frequency of the second frequency band.

10. The mobile terminal of claim 1 , further comprising at least one switch having one side connected to the terminal body and another side connected to the lower module.

11. A mobile terminal, comprising:
a terminal body having a front surface, a rear surface, and side surfaces extending from end portions of the rear surface toward the front surface, the terminal body being made of a metal;
a lower module coupled to a lower end of the terminal body and externally exposed to operate as a radiator of an antenna apparatus;
a non-metal member interposed between the terminal body and the lower module and forming a slot by spacing the terminal body and the lower module apart from each other; and
a dividing member crossing the non-metal member, and dividing an area where the terminal body and the lower module are electrically connected and generate an electric field, the dividing member dividing the slot into a first slot and a second slot,
wherein the antenna apparatus comprises first and second antenna resonating different frequency bands,
wherein the first antenna and the second antenna comprise a first feeder and a second feeder, respectively, connected to a main printed circuit board provided in the terminal body and generating the electric fields on the first slot and the second slot, respectively,
wherein the first feeder allows the electric field to be formed on the first slot, and the second feeder allows the electric field to be formed on the second slot,
wherein the lower module comprises first and second members and a connecting portion connecting end portions of the first and second member to each other,
wherein the first member is exposed to the front surface of the mobile terminal, and the second member is exposed to the rear surface of the mobile terminal,
wherein the first and second members and the connecting portion are made of a metal,
wherein the mobile terminal further comprises a first stub disposed at the first slot, the first slot comprising one side connected to the lower module and another side forming a first open end and a second stub disposed on the second slot, the second slot having one side connected to the lower module and another side forming a second open end,
wherein the first stub is configured to implement a first resonant frequency of a first frequency band, and
wherein the second stub is configured to implement a second resonant frequency of a second frequency band.
