- H01Q: ANTENNAS, i.e. RADIO AERIALS (radiators or antennas for microwave heating H05B6/72)

## Abstract

A mobile terminal including a first frame; a second frame which slides with respect to the first frame; a first horn antenna which is disposed in the first frame; and a second horn antenna which is disposed in the second frame and wirelessly communicates with the first horn antenna. The mobile terminal can omit a physical signal line for transmitting a signal between an electronic component mounted to the first frame and an electronic component mounted to the second frame, and thus can prevent the breakage of the signal line according to sliding movements.

## Claims

### Claim 1

A mobile terminal comprising:
a first frame;
a second frame configured to switch to an extended mode by sliding in a first direction with respect to the first frame or to switch to a basic mode by sliding in a second direction opposite to the first direction;
a main board mounted on the second frame;
a first electronic component mounted on the first frame;
a first antenna fixed to a rear surface of the first frame and oriented in the first direction;
an auxiliary board configured to connect to the first electronic component and the first antenna; and
a second antenna located on the main board and oriented in the second direction to face the first antenna, wherein the second antenna is in wireless communication with the first antenna; and
an antenna cover located on the rear surface of the first frame and covering the first antenna and a gap between the first antenna and the second antenna to form a shielding passage between the first antenna and the second antenna.

### Claim 2 (depends on 1)

The mobile terminal claim 1, wherein the antenna cover protrudes from a rear surface of the first frame, and
wherein the second frame further includes a concave portion receiving the antenna cover therein in the basic mode.

### Claim 3 (depends on 1)

The mobile terminal of claim 1, wherein the antenna cover includes a multi-stage structure with stages overlapping each other in the basic mode and spreading while sliding in the extended mode, and
wherein one side of the multi-stage structure is fixed to the first frame and the other side of the multi-stage structure is fixed to the second frame.

### Claim 4 (depends on 3)

The mobile terminal of claim 3, further comprising:
a driving motor located on the second frame;
a pinion gear configured to receive a rotational force of the driving motor; and
a rack gear located on the rear surface of the first frame,
wherein at least a portion of the rack gear is located in front of the antenna cover in the extended mode.

### Claim 5 (depends on 3)

The mobile terminal of claim 3, wherein the antenna cover includes:
multi-stage shells made of a non-conductive material; and
EMI paint applied to inner sides of the multi-stage shells.

### Claim 6 (depends on 2)

The mobile terminal of claim 2, wherein the second antenna is mounted on the second frame to be oriented in the second direction opposite to the first direction at an end of the concave portion.

### Claim 7 (depends on 1)

The mobile terminal of claim 1, wherein the first electronic component is mounted on the first frame and includes at least one of a camera, a receiver, and a proximity sensor located inside the antenna cover.

### Claim 8 (depends on 1)

The mobile terminal of claim 1, further comprising:
a battery mounted on the second frame;
a power pin connected to the battery and protruding from a front surface of the second frame facing the first frame; and
a power terminal located on the auxiliary board,
wherein the power pin contacts to the power terminal and moves along the power terminal when the second frame slides.

### Claim 9 (depends on 8)

The mobile terminal of claim 8, wherein the power terminal is elongated in the first direction.

### Claim 10 (depends on 9)

The mobile terminal of claim 9, wherein the first frame includes:
a first rear surface exposed to the outside in the extended mode; and
a second rear surface covered by the second frame in the extended mode,
wherein the power terminal is located on the second rear surface.

### Claim 11 (depends on 1)

The mobile terminal of claim 1, further comprising:
a display unit including a fixed part coupled to a front surface of the first frame and a variable part oriented in the first direction of a first area and bent while surrounding the second frame; and
a display driving IC fixed to the first frame and connected to the auxiliary board.

### Claim 12 (depends on 1)

The mobile terminal of claim 1, wherein the first antenna and the second antenna include horn antennas using a WiGig communication in a 60 GHz band.

### Claim 13

A mobile terminal comprising:
a first frame;
a second frame configured to switch to an extended mode by sliding in a first direction with respect to the first frame or to switch to a basic mode by sliding in a second direction opposite to the first direction;
a main board mounted on the second frame;
a first electronic component mounted on the first frame;
an auxiliary board configured to connect the first electronic component;
a battery mounted on the second frame;
a power pin connected to the battery and protruding from a front surface of the second frame facing the first frame; and
a power terminal elongated in the first direction on the auxiliary board,
wherein the power pin contacts to the power terminal and moves along the power terminal when the second frame slides,
wherein the first frame includes:
a first rear surface exposed to the outside in the extended mode; and
a second rear surface covered by the second frame in the extended mode, and
wherein the power terminal is located on the second rear surface.

### Claim 14 (depends on 13)

The mobile terminal of claim 13, further comprising:
a first antenna fixed to the first frame and connected to the auxiliary board; and
a second antenna located on the main board.
