The touch sensor may be configured to convert a change in a pressure applied to a specific portion of the display unit 151 or a capacitance generated in a specific portion of the display unit 151 into an electrical input signal. The touch sensor can be configured to detect not only the position and area to be touched but also the pressure at the time of touch.

If there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller.

As shown in the drawings, a mobile terminal according to an exemplary embodiment of the present invention is a mobile terminal having a loop antenna. The loop antenna uses a part of a case formed along a side surface of a terminal body as a part of a conductive loop.

Referring first to FIG. 3, a circuit board 182 is embedded in a terminal body. The circuit board 182 may be mounted on the first case 101 and the second case 102, for example, or may be mounted on a separate internal structure. Hereinafter, the first case 101 and the second case 102 are separately described, but the present invention is not limited thereto, and the cases 101 and 102 may be integrally formed. According to the drawing, the circuit board 182 is disposed so as to cover the inner surface of the second case 102.

Various electronic elements are mounted on one surface of the circuit board 182, and a shield member (not shown) for protecting the electronic elements may be mounted on the one surface. The shield member may be electrically connected to the circuit board to extend the ground of the circuit board.

The circuit board 182 may be configured as an example of a control unit for operating various functions of the mobile terminal. A plurality of circuit boards 182 may be provided and perform the function of the control unit by combining them. The circuit board 182 is also electrically connected to the antenna device and is configured to process a radio signal (or radio electromagnetic wave) transmitted and received by the antenna device.

4, the antenna device includes a conductive member 140, a power supply connection 151, a ground connection 152, and a ground 153. [

The conductive member 140 is electrically connected to the circuit board 182 and is configured to transmit and receive wireless signals to be processed by the circuit board 182. The conductive member 140 is electrically connected to the circuit board 182 by the power supply connection unit 151 and receives power from the circuit board 182 through the conductive connection member 151.

The power supply connection unit 151 electrically connects the power supply device (not shown) and the conductive member 140. For this connection, the feed connection unit 151 may include a feed plate, a power supply clip, and a feeder line. Here, the feed plate, the feed clip, and the feeder line are electrically connected to each other to transmit a current (or voltage) fed through the feeder to the conductor of the spinneret. Here, the feed line may include a microstrip printed on a substrate.

The ground 153 may be one layer of a circuit board, a frame of a display (or a display device), the shield member, or the like, or a combination thereof. The ground connection portion 152 is configured to electrically connect the conductive member 140 and the ground 153. That is, the current supplied through the ground connection part 152 is short-circuited to the conductive member 140.

The ground connection part 152 electrically connects the electric ground (ground) and the conductive member 140 to ground the conductive member 140. [ Here, the ground connection portion 152 may include a ground plate, a ground clip, and a ground line. Further, the lengths of the paths can be formed differently by forming the ground wires to have different lengths.

Referring to these drawings, the conductive member 140 forms a pattern of a loop antenna. The power supply connection part 151 is disposed at one end of the conductive member 140 and the ground connection part 152 is disposed at the other end (opposite end of the end) of the conductive member 140. Through this, a conductive loop may be formed which leads to the ground (or circuit board), the power supply connection portion 151, the conductive member 140, the ground connection portion 152, and the ground 153.

To describe the conductive member 140 in more detail, the conductive member 140 forms a loop antenna to be wound a plurality of times. For example, the conductive member 140 includes first and second loop patterns 141, 142.

The first and second loop patterns 141 and 142 are looped at least partially, and are electrically connected to each other. According to the drawing, the first and second loop patterns 241 and 242 are each made to be wound in two layers in the xy plane.

The second loop pattern 142 extends in the first loop pattern 141 so that the first and second loop patterns 141 and 142 form a closed loop. One of the first and second loop patterns 141 and 142 is connected to the circuit board 182 via the power supply connection part 151 and the other is connected to the ground 153 via the ground connection part 152. [ ).

As described above, the ground (or circuit board), the power supply connection portion 151, the first and second loop patterns 141 and 142, the ground connection portion 152, and the ground 153 are combined to form a Code Division Multiple Access (CDMA) , A PCS (Personal Communication System) and a DCS (Digital Cellular System) band (1700 to 1900 MHz), or a W CDMA (Wideband CDMA) communication band (2.4 GHz) It is possible to form a conductive loop operated in any one of the bands.

This conductive loop is formed so as to satisfy a half wavelength of a specific frequency. That is, the conductive loop is composed of a ground plane and a λ / 2 double winding loop antenna. Furthermore, the conductive loop can maximize the polarization characteristic by an L-type or the like, and one or more? / 4 branches may be added to secure a bandwidth.

The branch may extend at any point in the conductive loop to form a sub-emitter that extends the bandwidth at a particular frequency. In this case, the conductive member 140 operates as a carcass for a specific frequency.

It is general that the loop antenna has a loss resistance larger than the radiation resistance, so that it has a low radiation efficiency. Therefore, in order to apply the loop antenna to a terminal, a large loop having a large cross-sectional area is required, but this increases the size of the terminal.

Referring to FIG. 5, it can be seen that the radiation efficiency (radiation resistance) increases as the number of windings increases in a loop antenna wound a plurality of times. Therefore, the loop antenna of the present invention has a high radiation efficiency even in a narrow area.

3 and 4, the conductive member 140 is at least partially exposed to the outside so as to form an appearance of the terminal body. For example, the conductive member 140 includes first and second conductive portions 143 and 144. At least one of the first and second conductive portions 143 and 144 may be included in the second loop pattern.

The first conductive part 143 is exposed to the outside of the terminal body and the second conductive part 144 is electrically connected to the first conductive part 143. The first conductive part 143 is exposed to the outside of the terminal body, 1 < / RTI >

In this embodiment, the first and second loop patterns 141 and 142 are spaced apart from each other in the thickness direction of the terminal body, and the first conductive part 143 forms a part of the first loop pattern 141 And the second conductive part 144 forms a part of the second loop pattern 142.

As an example of such a structure, the first and second conductive portions 143 and 144 are disposed parallel to each other on the side of the terminal. That is, the first and second conductive portions 143 and 144 are formed of a conductive metal material as a part of the cover forming the outer appearance of the terminal, and operate as a main radiator in the loop antenna. In this way, a plurality of rims can be realized which serve as the main radiating element of the antenna in the terminal and are used as decorations of the terminal exterior by being spaced apart from each other by a specific distance.

As described above, the spacing space between the first and second conductive portions 143 and 144 is formed on the side surface of the terminal, and the dielectric forming the case of the main body is filled in the spacing space. That is, the spacing space is filled by at least one of the first and second cases 101 and 102 (the first case in this embodiment). As an example of such a dielectric, the first and second cases 101 and 102 are made of a synthetic resin material.

In the first and second loop patterns 141 and 142, the portions except for the first and second conductive portions 143 and 144 may be formed in the carrier 154. That is, a conductive pattern is formed on the carrier 154, and the projections may protrude from the conductive pattern to be connected to the first and second conductive portions 143 and 144.

3 and 4, the first and second loop patterns 141 and 142 are disposed at corners of the terminal body, respectively, and the ground 153 is overlapped with the first and second loop patterns at the corners . The ground 153 has a shape in which a rectangular corner is cut, and a carrier 154 is disposed at the cut-out portion.

The dielectric or metal body is disposed in the spacing space between the first and second loop patterns 141 and 142 so that the resonant frequency of the conductive member 140 is adjusted. The resonance frequency can be adjusted by the material and amount of the dielectric, the position of the metal body, and the like.

As an example of the metallic body, electronic elements are arranged in a space defined by the first and second loop patterns 141 and 142. [ As an example of an electronic device, a microphone 122 is disposed between the first and second loop patterns 141 and 142. However, the present invention is not limited thereto, and the electronic device may be various types such as a speaker and a receiver. More specifically, the microphone 122 may be mounted to the carrier 154 and disposed in the interior space of the carrier 154.

According to the drawing, in the case, a through hole 122a is formed in a portion corresponding to the spacing space of the first and second conductive portions 143 and 144. The sound micro-received through the through hole 122a can be easily introduced from the outside. If the speaker is disposed in the spacing space, the through hole 122a may be a speaker hole.

In general, the electric elements are not mounted in the space where the radiation efficiency of the antenna is hindered. However, in a loop antenna, when the magnetic field strength is increased, that is, when a ferrite loop is formed, the radiation efficiency is increased. Therefore, the microphone 122 disposed between the first and second loop patterns 141 and 142 functions as ferrite and increases the magnetic field strength of the patterns 141 and 142, 140 is increased.

Referring to these drawings, a bezel member 160 is mounted to the case 101, 102 of the terminal, and the bezel member 160 includes first and second bezel portions 161, 162.

The first bezel portion 161 is formed on the same plane as the first conductive portion 143 and the second bezel portion 162 is formed on the second conductive portion 144 so as to face the first bezel portion 161. [ As shown in FIG. The bezel member 160 may be made of the same metal as the conductive member 140 for the purpose of apparent unification.

The bezel member 160 and the conductive member 150 are disposed between the first bezel 161 and the first conductive portion 143 and between the second bezel 162 and the second conductive portion 144, A gap 155 is formed. Due to the gap 155, the first and second conductive portions 143 and 144 can form a conductive loop. That is, even if the bezel member 160 includes a conductive metal material, the flow of current between the conductive member 150 and the conductive member 150 is blocked, so that the conductive member 150 can operate as a loop antenna.

Referring to the voltage standing wave ratio of FIG. 6, the mobile terminal of the present invention can be used in a communication system such as a CDMA (Code Division Multiple Access) and a GSM (Global System for Mobile communication) communication band (800 to 1000 MHz), a PCS (1700 ~ 1900MHz), the resonance frequency is shown.

FIG. 7 is a perspective view showing a state in which a display portion is removed in part A of FIG. 1 according to another embodiment of the present invention, and FIG. 8 is a conceptual view of a loop antenna according to another embodiment of the present invention. As described above, in the present embodiment, the same or similar components are given the same or similar reference numerals, and the description thereof is replaced with the first explanation.

As shown, the mobile terminal uses part of the case formed along the side of the terminal body as part of the conductive loop.

For example, the first and second loop patterns 241 and 242 are each made to wind in the yz plane. The first and second loop patterns 241 and 242 are arranged to face each other in the longitudinal direction (or the width direction) of the terminal body, and the first and second conductive parts 243 and 244 are disposed in the second loop pattern (242).

In this embodiment, the portions connecting the first and second conductive parts 243 and 244 are also exposed to the outside, so that the entire second loop pattern 242 is exposed to the outside. That is, the second loop pattern 242 is exposed to the outside of the terminal body from the side, and the first loop pattern 241 is embedded in the body.

Such a loop antenna formed on the lower side of the terminal is formed such that the main radiation section is directed outwardly in the longitudinal direction from the lower end of the terminal so as to reduce the deterioration of the radiation characteristic due to the hand effect effect in the high frequency band have.

Also, the first and second loop patterns 241 and 242 may be physically disconnected from each other. In this case, at least a part of the first and second loop patterns 241 and 242 may be closely arranged so as to be electrically connected to each other by coupling.

Modifications to the antenna apparatus of the present invention will be described below with reference to Figs. 9A to 9D. 9A to 9D are conceptual diagrams showing a modified example of the antenna device of the present invention.

Referring to FIG. 9A, the first and second loop patterns 341 and 342 are disposed on adjacent sides of the terminal body, respectively, so as to face the directions perpendicular to each other. That is, the first and second loop patterns 341 and 342 are both exposed to the outside of the terminal, and are disposed on both sides perpendicular to each other at corners of the terminal.

For example, the feed connection portion 351 is connected to the first loop pattern 341 formed on the lower side surface of the terminal, the ground connection portion 352 includes the second loop pattern 342 formed on the side perpendicular to the lower side surface, Lt; / RTI >

According to this structure, the loop antenna is designed as an L-type, and the first and second loop patterns 341 and 342 radiate radio signals in directions perpendicular to each other. That is, through this, the loop antenna can take both vertical and horizontal polarizations.

In the illustrated embodiment, a user input unit 333 for receiving a control command is disposed in a portion defined by the first or second loop patterns 341 and 342. The user input portion 333 may be enclosed by a second loop pattern 342, for example, as a side key. As described above, since the user input unit 333 is disposed within the second loop pattern 342, the degree of freedom in designing the terminal can be improved and the size of the terminal can be made more compact.

Referring to FIG. 9B, the first and second conductive portions 443 and 444 are at least partially bent so as to extend along the edges of the terminal body, which intersect with each other. More specifically, the first and second loop patterns 441 and 442 are disposed in the thickness direction of the terminal, and the first and second loop patterns 441 and 442 are exposed to the outside so that the loop patterns 441 and 442 emit radio signals in the L- The second conductive portions 443 and 444 are formed so as to be bent at corners of the terminal. Particularly, in this case, the loop antenna can have a sufficient loop length without being wound a plurality of times.

Referring to FIG. 9C, the first and second conductive loops 541 and 542 are spaced apart in the longitudinal direction of the terminal, and the second conductive loop 542 exposed to the outside occupies most of the lower side of the terminal .

According to the embodiment, a cover that can be opened and closed can be mounted on the lower end of the terminal, and a second conductive loop 542 can be formed along the outer edge of the cover. In this modification, the terminal is formed such that the battery 591 is inserted therein. According to this structure, a mechanism may be realized in which the antenna radiates a radio signal to the lower end of the terminal while the battery 591 is mounted or detached through the lower end.

Referring to FIG. 9D, a user input unit 631 for receiving a control command of a user of the terminal body is formed. The user input unit 631 is disposed inside the first and second conductive loops 641 and 642, thereby enabling a more compact terminal. In addition, in the present modification, if the user input unit 631 is a transparent touch screen, the first and second conductive loops 641 and 642 may be configured as a frame surrounding the transparent region.

10 is an exploded perspective view showing a mobile terminal according to another embodiment of the present invention. As described above, in the present embodiment, the same or similar components are given the same or similar reference numerals, and the description thereof is replaced with the first explanation.

As shown in the figure, the mobile terminal according to the present embodiment is a mobile terminal having a loop antenna, and the loop antenna is disposed inside the terminal. More specifically, the loop antenna is configured to be wound a plurality of times and includes first and second loop patterns 741 and 742.

The first loop pattern 741 is connected to the circuit board, and at least part of the loop pattern 741 is wound so that a current corresponding to a radio signal to be transmitted and received flows in a clockwise direction or a counterclockwise direction. The second loop pattern 742 is formed so that the current flows in the same direction as the first loop pattern 741 at a portion facing the first loop pattern 741.

More specifically, a recessed battery housing chamber is formed in the second case 702, and a covering cover 792 for opening and closing the housing chamber is mounted. The cover 792 is formed in a plate shape to cover the accommodation chamber and the battery 791.

Referring to these drawings, a carrier 754 is mounted on the outer surface of the second case 702, and first and second loop patterns 741 and 742 of a specific pattern are formed on the carrier 754. The first and second loop patterns 741 and 742 are wound in the same direction so that the flow direction of the current is the same, and electronic elements are disposed between the first and second loop patterns 741 and 742. With this structure, the radiation efficiency is increased, and the loop antenna can be implemented in the terminal.

Although the first and second loop patterns 741 and 742 are formed at positions covered by the cover 792 in the present embodiment, the present invention is not limited thereto. For example, the first and second loop patterns 741 and 742 may be formed on a portion of the outer surface of the second case 702 that is not covered by the cover 792.

The mobile terminal according to an exemplary embodiment of the present invention is not limited to the configuration and method of the embodiments described above, but all or some of the embodiments may be selectively combined .
