Abstract

In an internal antenna, a first antenna part is disposed on a side of a mobile telecommunication terminal body having at least first and second peripheral surfaces and sides. The first antenna part processes a signal of a first band. Also, a second antenna part is disposed on one of the peripheral surfaces of the mobile telecommunication body. The second antenna part processes a signal of a second band.

Claims

1. An internal antenna having a perpendicular arrangement, said antenna comprising:

a first chip antenna part for processing a signal of a first band, the first chip antenna part being disposed on a side surface of a mobile telecommunication terminal body which also has opposite first and second main surfaces, the side surface connecting said main surfaces and being perpendicular to at least said first main surface;

a second chip antenna part for processing a signal of a second band different from the first band, the second chip antenna part being disposed on the first main surface of the mobile telecommunication terminal body, wherein the first and second chip antenna parts have an identical lengthwise direction;

a first feeding part for feeding current to the first and second chip antenna parts through an equal feeding line;

a third chip antenna part for processing a signal of a third band, the third chip antenna part being disposed on the side surface of the mobile telecommunication terminal body on which the first chip antenna part is disposed;

a fourth chip antenna part for processing a signal of a fourth band different from the third band, the fourth chip antenna part being disposed on the first main surface of the mobile telecommunication terminal body on which the second chip antenna part is disposed; and

a second feeding part for feeding current to the third and fourth chip antenna parts through an equal feeding line, wherein the second feeding part is electrically connected to the first feeding part.

2. The internal antenna according to claim 1, wherein

the first and second chip antenna parts define a first antenna structure;

the third and fourth chip antenna parts define a second antenna structure;

the first and second antenna structures are serially connected by a conductive line which connects a first middle point of the first feeding part between the first and second chip antenna parts with a second middle point of the second feeding part between the third and fourth chip antenna parts.

3. The internal antenna according to claim 2, wherein second band is higher than the first band, and the fourth band is higher than the third band.

4. The internal antenna according to claim 1, wherein

the first and second chip antenna parts define a first antenna structure;

the third and fourth chip antenna parts define a second antenna structure;

the first and second antenna structures are connected in parallel with ends of the first and second feeding parts being commonly connected to a common feeding part.

5. The internal antenna according to claim 4, wherein second band is higher than the first band, and the fourth band is higher than the third band.
