Abstract

A conductive border surrounds a terminal along a direction. A mobile terminal includes a wireless transmission/reception circuit to output a signal for a wireless communication of the mobile terminal; a conductive border that forms side surfaces of the mobile terminal; a ground element electrically connected to the conductive border; a first antenna element electrically connected to the conductive border and the wireless transmission/reception circuit; and a second antenna element electrically connected to the conductive border and the ground element.

Claims (27)

1. A mobile terminal, comprising:

a wireless transmission/reception circuit to output a signal for a wireless communication of the mobile terminal;

a continuous 1 conductive border that surrounds side surfaces of the mobile terminal;

a ground element electrically connected to the conductive border at a discrete location through a first connection wire;

a first antenna radiating length comprising a first portion of the conductive border and a first antenna element electrically connected to the conductive border through a first contact and a first connector and the wireless transmission/reception circuit through a second connector 2 , the first antenna radiating length configured to form a first resonance by a first path extending from one end of the first antenna through the first contact and first connector to the conductive border and along the conductive border in a first direction to the first connection wire, and a second resonance by a second path extending from the one end of the first antenna through the first contact and the first connector to the conductive border and along the conductive border in a second direction opposite to the first direction:

and a second antenna radiating length comprising a second portion of the conductive border and a second antenna element electrically connected to the conductive border and the ground element, the second antenna configured as a second continuous conductive form.

2. The mobile terminal of claim 1 , wherein the conductive border has a continuous loop shape along sides of the mobile terminal, the sides corresponding to a periphery of a front surface of the mobile terminal, the front surface comprising a display screen.

3. The mobile terminal of claim 1 , wherein the conductive border comprises a first conductive portion and a second conductive portion, the first conductive portion and the second conductive portion being connected to the first antenna element.

4. The mobile terminal of claim 3 , wherein at least one of the first conductive portion and the second conductive portion is connected to the wireless transmission/reception circuit.

5. The mobile terminal of claim 3 , wherein the first conductive portion and the first antenna element provide a first radio frequency band, and the second conductive portion and the first antenna element provide a second radio frequency band.

6. The mobile terminal of claim 3 , wherein the first conductive portion and the second conductive portion are electrically connected to the ground element by a connector.

7. The mobile terminal of claim 3 , further comprising:

a third antenna comprising the first conductive portion, the third antenna being a loop antenna.

8. The mobile terminal of claim 7 , further comprising:

a fourth antenna connected to a third conductive portion of the conductive border.

9. The mobile terminal of claim 1 , wherein three or more portions of the conductive border are electrically connected to the ground element.

10. The mobile terminal of claim 1 , wherein the first antenna element or the second antenna element is electrically connected to two or more portions of the conductive border by connectors.

11. The mobile terminal of claim 1 , wherein the wireless transmission/reception circuit and the ground element are mounted on a printed circuit board arranged in the mobile terminal.

12. The mobile terminal of claim 1 , wherein the conductive border is made of conductive metal, and at least a portion of the conductive border that connects the first antenna element and the second antenna element is continuous.

13. The mobile terminal of claim 1 , wherein the first antenna element is relatively longer than the second antenna element.

14. A mobile terminal, comprising:

a wireless transmission/reception circuit to output a signal for a wireless communication of the mobile terminal;

a continuous conductive border that surrounds side surfaces of the mobile terminal; a ground element electrically connected to the conductive border at a first location through a first connection wire, and capacitively coupled to the conductive border at a second location;

a first antenna radiating length comprising a first portion of the conductive border and a first antenna element electrically connected to at least one of the conductive border through a first connector and the wireless transmission/reception circuit through a second connector, the first antenna radiating length configured to form a first resonance by a first path extending from one end of the first antenna through the first connector to the conductive border and along the conductive border in a first direction to the first connection wire, and a second resonance by a second path extending from the one end of the first antenna through the first connector to the conductive border and along the conductive border in a second direction opposite to the first direction to the second location;

and a second antenna radiating length comprising a second portion of the conductive boarder and a second antenna element electrically connected to the conductive border and the ground element, the second antenna configured as a second continuous conductive form.
