Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as " proximity touch & The act of actually touching an object on the screen is called a " contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

In the following, various embodiments may be embodied in a recording medium readable by a computer or similar device using, for example, software, hardware, or a combination thereof.

Referring to FIGS. 1B and 1C, the disclosed mobile terminal 100 includes a bar-shaped terminal body. However, the present invention is not limited thereto and can be applied to various structures such as a folder type, a flip type, a slide type, a swing type, and a swivel type in which a watch type, a clip type, a glass type or two or more bodies are relatively movably coupled . A description of a particular type of mobile terminal, although relevant to a particular type of mobile terminal, is generally applicable to other types of mobile terminals.

Here, the terminal body can be understood as a concept of referring to the mobile terminal 100 as at least one aggregate.

The mobile terminal 100 includes a case (for example, a frame, a housing, a cover, and the like) that forms an appearance. As shown, the mobile terminal 100 may include a front case 101 and a rear case 102. Various electronic components are disposed in the inner space formed by the combination of the front case 101 and the rear case 102. At least one metal frame may be additionally disposed between the front case 101 and the rear case 102.

A display unit 151 is disposed on a front surface of the terminal body to output information. The window 151a of the display unit 151 may be mounted on the front case 101 to form a front surface of the terminal body together with the front case 101. [ As the mobile terminal 100 has been miniaturized in recent years, the front case can be omitted and the front surface of the mobile terminal body can be configured with only the window 151a.

The mobile terminal 100 may have a metal frame 107 (see FIG. 3) supporting the backside of the display portion 151 for rigidity, and the metal frame 107 may include a metal material for rigidity. In addition to providing rigidity to the mobile terminal, it can serve as a ground with a large-area configuration including a conductive material, and can be connected to each component for grounding of electronic components such as an antenna.

The metal frame 107 may be configured not to be exposed to the outside, but may be formed integrally with the front case located on the front surface of the body or the side case 200 positioned on the side surface.

As the multimedia function is expanded, the size of the display unit 151 becomes larger and the size of the bezel located around the display unit 151 becomes smaller. Particularly, the upper part needs to secure a space for the camera 121, the sound output unit 152, the proximity sensor 141, and the like to be positioned, and physical buttons are disposed at the lower end to limit the size expansion of the display unit 151.

However, in recent years, the size of each component is minimized, and a user input unit 123 using a soft key is implemented instead of a physical button, so that a soft key is displayed on the screen only when necessary, and if unnecessary, the size of the screen can be increased.

In some cases, electronic components may also be mounted on the rear case 102. Electronic parts that can be mounted on the rear case 102 include detachable batteries, an identification module, a memory card, and the like. In this case, a rear cover for covering the mounted electronic component can be detachably coupled to the rear case 102. Therefore, when the rear cover 103 is separated from the rear case 102, the electronic parts mounted on the rear case 102 are exposed to the outside.

These cases 101, 102, and 103 may be formed by injection molding of synthetic resin or may be formed of metal such as stainless steel (STS), aluminum (Al), titanium (Ti), or the like.

The mobile terminal 100 of the present embodiment includes a side case 200 surrounding the side surface, and the side case 200 may include a metal material.

The plurality of conductive members may be partitioned into slits 221, 222, 223 (see FIG. 3), and the slits may be filled with a non-metallic material.

The mobile terminal 100 may be configured such that one case provides the internal space, unlike the above example in which a plurality of cases provide an internal space for accommodating various electronic components. In this case, a unibody mobile terminal 100 in which synthetic resin or metal is connected from the side to the rear side can be realized.

Meanwhile, the mobile terminal 100 may include a waterproof unit (not shown) for preventing water from penetrating into the terminal body.

The display unit 151 may include a touch sensor that senses a touch with respect to the display unit 151 so that a control command can be received by a touch method. When a touch is made to the display unit 151, the touch sensor senses the touch, and the control unit 180 generates a control command corresponding to the touch based on the touch. The content input by the touch method may be a character or a number, an instruction in various modes, or a menu item that can be designated.

The touch sensor may be a film having a touch pattern and disposed between the window 151a and a display (not shown) on the rear surface of the window 151a, or may be a metal wire . Alternatively, the touch sensor may be formed integrally with the display. For example, the touch sensor may be disposed on a substrate of the display or inside the display.

In this way, the display unit 151 can form a touch screen together with the touch sensor. In this case, the touch screen can function as a user input unit 123 (see FIG. 1A). In some cases, the touch screen may replace at least some functions of the first operation unit 123a.

However, the present invention is not limited to this, and the sound may be configured to be emitted along an assembly gap (for example, a gap between the window 151a and the front case 101) between the structures. In this case, the appearance of the mobile terminal 100 can be made more simple because the hole formed independently for the apparent acoustic output is hidden or hidden.

The optical output unit 154 is configured to output light for notifying the occurrence of an event. Examples of the event include a message reception, a call signal reception, a missed call, an alarm, a schedule notification, an email reception, and reception of information through an application. The control unit 180 may control the light output unit 154 to terminate the light output when the event confirmation of the user is detected.

The first camera 121a processes an image frame of a still image or a moving image obtained by the image sensor in the photographing mode or the video communication mode. The processed image frame can be displayed on the display unit 151 and can be stored in the memory 170. [

The first and second operation units 123a and 123b may be collectively referred to as a manipulating portion as an example of a user input unit 123 operated to receive a command for controlling the operation of the mobile terminal 100 have. The first and second operation units 123a and 123b can be employed in any manner as long as the user is in a tactile manner such as touch, push, scroll, or the like. In addition, the first and second operation units 123a and 123b may be employed in a manner that the user operates the apparatus without touching the user through a proximity touch, a hovering touch, or the like.

In this figure, the first operation unit 123a is a touch key, but the present invention is not limited thereto. For example, the first operation unit 123a may be a mechanical key, or a combination of a touch key and a touch key.

The contents input by the first and second operation units 123a and 123b can be variously set. For example, the first operation unit 123a receives a command such as a menu, a home key, a cancellation, a search, and the like, and the second operation unit 123b receives a command from the first or second sound output unit 152a or 152b The size of the sound, and the change of the display unit 151 to the touch recognition mode.

On the other hand, a rear input unit 123c may be provided on the rear surface of the terminal body as another example of the user input unit 123. [ The rear input unit 123c is operated to receive a command for controlling the operation of the mobile terminal 100, and input contents can be variously set. For example, commands such as power on / off, start, end, scrolling, and the like, the size adjustment of the sound output from the first and second sound output units 152a and 152b, And the like can be inputted. The rear input unit 123c may be implemented as a touch input, a push input, or a combination thereof.

The rear input unit 123c may be disposed so as to overlap with the front display unit 151 in the thickness direction of the terminal body. For example, the rear input unit 123c may be disposed at the rear upper end of the terminal body so that the user can easily operate the terminal body by using the index finger when the user holds the terminal body with one hand. However, the present invention is not limited thereto, and the position of the rear input unit may be changed.

When the rear input unit 123c is provided on the rear surface of the terminal body, a new type of user interface using the rear input unit 123c can be realized. When the first operation unit 123a is not disposed on the front surface of the terminal body in place of at least a part of the functions of the first operation unit 123a provided on the front surface of the terminal body, The display unit 151 can be configured as a larger screen.

Meanwhile, the mobile terminal 100 may be provided with a fingerprint recognition sensor for recognizing the fingerprint of the user, and the controller 180 may use the fingerprint information sensed through the fingerprint recognition sensor as authentication means. The fingerprint recognition sensor may be embedded in the display unit 151 or the user input unit 123.

The microphone 122 is configured to receive the user's voice, other sounds, and the like. The microphone 122 may be provided at a plurality of locations to receive stereophonic sound.

The interface unit 160 is a path through which the mobile terminal 100 can be connected to an external device. For example, the interface unit 160 may include a connection terminal for connection with another device (for example, an earphone or an external speaker), a port for short-range communication (for example, an infrared port (IrDA Port), a Bluetooth port A wireless LAN port, or the like), or a power supply terminal for supplying power to the mobile terminal 100. The interface unit 160 may be implemented as a socket for receiving an external card such as a SIM (Subscriber Identification Module) or a UIM (User Identity Module) or a memory card for storing information.

And a second camera 121b may be disposed on a rear surface of the terminal body. In this case, the second camera 121b has a photographing direction which is substantially opposite to that of the first camera 121a.

The second camera 121b may include a plurality of lenses arranged along at least one line. The plurality of lenses may be arranged in a matrix form. Such a camera can be named an 'array camera'. When the second camera 121b is configured as an array camera, images can be taken in various ways using a plurality of lenses, and a better quality image can be obtained.

The flash 124 may be disposed adjacent to the second camera 121b. The flash 124 shines light toward the subject when the subject is photographed by the second camera 121b.

And a second sound output unit 152b may be additionally disposed in the terminal body. The second sound output unit 152b may implement a stereo function together with the first sound output unit 152a and may be used for implementing a speakerphone mode in a call.

The terminal body may be provided with at least one antenna for wireless communication. The antenna may be embedded in the terminal body or formed in the case. For example, an antenna constituting a part of the broadcast receiving module 111 (see FIG. 1A) may be configured to be able to be drawn out from the terminal body. Alternatively, the antenna may be formed in a film type and attached to the inner surface of the rear cover 103, or a case including a conductive material may be configured to function as an antenna.

The terminal body is provided with a power supply unit 190 (see FIG. 1A) for supplying power to the mobile terminal 100. The power supply unit 190 may include a battery 191 built in the terminal body or detachable from the outside of the terminal body.

The battery 191 may be configured to receive power through a power cable connected to the interface unit 160. In addition, the battery 191 may be configured to be wirelessly chargeable through a wireless charger. The wireless charging may be implemented by a magnetic induction method or a resonance method (magnetic resonance method).

The rear cover 103 is configured to be coupled to the rear case 102 so as to cover the battery 191 to restrict the release of the battery 191 and to protect the battery 191 from external impact and foreign matter . When the battery 191 is detachably attached to the terminal body, the rear cover 103 may be detachably coupled to the rear case 102.

The mobile terminal 100 may be provided with an accessory that protects the appearance or supports or expands the function of the mobile terminal 100. [ One example of such an accessory is a cover or pouch that covers or accommodates at least one side of the mobile terminal 100. [ The cover or pouch may be configured to interlock with the display unit 151 to expand the function of the mobile terminal 100. Another example of an accessory is a touch pen for supplementing or extending a touch input to the touch screen.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

As the multimedia function becomes important, the wireless communication technology performed by the mobile terminal is performed in various forms such as a short distance, a long distance, or an apparatus. Since different frequency bands are used, different challenge members must be used.

2. Description of the Related Art [0002] In recent years, as a wireless communication technology has developed, a large amount of data can be transmitted and received. To support this, a multiple input multiple output (MIMO) technique for simultaneously or sequentially transmitting and receiving signals of the same frequency band can be used. It is possible to increase the number of antennas of the base station and the mobile terminal 100 by more than one to transmit data over a plurality of paths and detect a signal received through each path at the receiving end, thereby reducing interference and lowering the transmission rate. In order to apply the MIMO technique, it is necessary to increase the number of conductive members within a limited size of the mobile terminal.

Since the conductive member forms an electromagnetic field, the conductive member is influenced by the neighboring conductive material. As a result, interference may occur between the conductive members disposed adjacent to each other, thereby deteriorating the performance of the wireless signal. Thus, it can be attached to the case for placement in the outer part of the mobile terminal, or the case itself can be used as the conductive member.

As the size of the display unit increases, the size of the left and right bezels of the mobile terminal is close to zero, so that the side case at the left and right of the display unit is difficult to function as a conductive member substantially. You can implement the Challenge member separately.

FIG. 2 is a view showing an antenna structure of a conventional mobile terminal 100, and FIG. 2 is a view as seen from the back direction of the mobile terminal. A metal frame 5 is seated on the back surface of the display unit 8 and the main board 7 is seated thereon. An antenna is a device that transmits a signal through an electric field (e-field) formed by applying power to a conductive object. The side case 3 of the mobile terminal may include a metal material and the side case 3 may be used as an antenna when power is supplied to the side case 3 made of metal through the feed parts 6a and 6b .

An antenna can transmit and receive data while resonating with a signal (resonance frequency) of a specific frequency band. Since the resonance frequency is determined by the length of the radiator, it is possible to divide the side case 3 with the slit 4 as shown in Fig. 2 to realize a conductive member having a length corresponding to the resonance frequency.

The conductive member 3 is disposed apart from the metal frame 5 mounted inside the mobile terminal. One side of the conductive member 3 is connected to the metal frame 5 and the other side is not connected, so that a slot-shaped antenna having one side closed and the other side opened can be formed.

It is necessary to reduce the size of the bezel located around the display unit 8 in order to increase the area of the display unit 8 because the display unit 8 takes charge of input as well as output. The distance between the side case 3 and the metal frame 5 and the display unit 8 is reduced by reducing the bezel. In particular, the distance from the display flexible board 9 affects antenna performance. The display flexible board 9 connects the driving IC for controlling each pixel of the display unit 8 and the main board 7 and extends from the display unit 8 to connect between the metal frame 5 and the side case 3 And extends to the main board 7 located on the rear surface of the metal frame 5.

Since the display flexible board 9 passes between the side case 3 and the metal frame 5, the interval c of the slots is substantially the same as the interval between the display flexible board 9 and the side case 3 . In order to secure the antenna performance, the interval (c) of the slots should be 2 mm or more.

The space between the side case 3 and the display flexible board 9 must be ensured in order to prevent deterioration of the antenna performance, which is an obstacle in reducing the size of the bezel at the lower end of the mobile terminal 100. [

Since the antenna using the side case 3 has the largest electric field in the slit portion 4, when the slit 4 is disposed adjacent to the metal frame 5 or the display flexible substrate 9, . It is difficult to reduce the size of the lower end bezel of the mobile terminal 100 by disposing the slit 4 apart from the display flexible substrate 9 in order to secure the wireless communication performance.

3 is a view showing the arrangement of the metal frame 107, the side case 200, and the display unit 151 of the mobile terminal 100 of the present invention. The mobile terminal 100 of the present invention can provide the display unit 151 of a large size by reducing the size of the bezel while ensuring antenna performance. The mobile terminal 100 includes a metal frame 107, a main board 181, a side case 200 and a display unit 151. The side case 200 includes slits 221, 222 and 223, And a plurality of conductive members 211, 212, and 213 partitioned by the conductive members 211, 212, and 213, respectively.

The metal frame 107 is made of a rigid metal material. The front surface of the metal frame 107 supports the rear surface of the display unit 151, and the rear surface thereof provides a mounting portion on which various components such as the main board 181 are mounted. The metal frame 107 not only provides the rigidity of the mobile terminal 100 but also is made of a large-area conductive material, and serves as a ground.

The display unit 151 is mounted on the front surface of the metal frame 107. The main board 181 is positioned on the rear surface of the metal frame 107 and is connected to the driving IC 1513, see Fig. 4) and the main board 181 are connected to each other. The display flexible substrate 1515 is bent at the end of the metal frame 107 and connected to the main substrate 181.

The side case 200 located around the metal frame 107 has a lower end (first side) spaced apart from the metal frame 107 by a predetermined distance, and the left and right portions 3 sides) are connected to the metal frame 107. [ The side case 200 of the present invention is such that a portion of the side surface 200 connected to the metal frame 107 on the second side surface and the side surface of the third side surface is spaced from the first side surface, And extends to the side and the third side.

Two slits 221 (first slits 221 and second slits 222) are formed on the first side of the side case 200 to form L-shaped first conductive members (first slits 221 and second slits 222) located on the first side and the second side 211, a L-shaped second conductive member 212 located on the first and third sides, and a third conductive member 213 located between the first conductive member 211 and the second conductive member 212 ). ≪ / RTI >

The first antenna (Ant.1) and the second conductive member (212) located on the left side of the first conductive member (211) and the metal frame (107) And the metal frame 107 form slots, and the antenna implemented is called a second antenna Ant.2.

The present embodiment differs from the first embodiment in that the first antenna Ant.1 and the second antenna Ant.2 are distributed from the first side to the second side and the third side without using the third conductive member 213 as an antenna So that the influence of the display flexible substrate 1515 on the antenna can be minimized. That is, since the distance c ₂ between the display flexible board 1515 at the lower end and the side case 200 does not affect the antenna performance, the size of the bezel can be reduced.

4 is a cross-sectional view of A-A and B-B in Fig. Referring to FIG. 4 (a), if the spacing distance a between the metal frame 107 and the side case 200 is 1 mm or more, the antenna performance can be more than the reference value. If the space between the metal frame 107 and the side case 200 is too wide, the size of the bezel on the right and left sides of the mobile terminal 100 becomes large, so that a is preferably 3 mm or less.

The distance c ₁ between the display unit 151 at the lower end of the mobile terminal 100 and the side case 200 is a distance between the first conductive member 211 or the second conductive member 212 and the display unit 151. That is, since the size of c ₁ affects the performance of the antenna, it should be secured at 1.5 to 2 mm or more.

Since the third conductive member 213 must be independent of the other conductive members and must be independent of each other, the metal flexible display flexible substrate 1515 must be spaced apart from the contact but the third conductive member 213 is not used as a radiator The distance c2 between the display flexible board 1515 at the lower end of the mobile terminal 100 and the side case 200, that is, the third conductive member 213 may be about 0.3 mm.

Conventionally, the distance between the side case 200 and the display flexible substrate 1515 should be 2 mm or more. However, since 0.3 mm is sufficient in this embodiment, the size of the bezel at the lower end of the mobile terminal 100 can be reduced.

Since the side case 3 of the lower side is used as an antenna, the slit 4 and the display flexible substrate 9 can be prevented from being deteriorated by the overlap of the slit 221 and the display flexible substrate 1515, There has been a limit in reducing the size of the lower bezel of the display unit to secure wireless communication performance.

However, according to the present invention, the first conductive member 211 and the second conductive member 212 may be disposed so as not to overlap the display flexible substrate 1515 by using the antenna as a side surface of the mobile terminal 100. [ That is, since the display flexible substrate 1515 and the slits 221 and 222 are not overlapped with each other, the radiation can smoothly appear at the slits 221 and 222.

However, when the user grasps the mobile terminal 100 by hand, the mobile terminal 100 should be separated from the left and right edges by a predetermined distance d or more in the inward direction since the user can reach the bottom edge of the mobile terminal 100. This depends on the overall size of the mobile terminal 100, and a length of about 12 mm to about 17 mm should be secured to prevent deterioration of the antenna performance caused by the hand. The length of the first portion 211a of the first conductive member 211 and the length of the third portion 212a of the second conductive member 212 may be different from each other, (D) in which the first portion 211a and the third portion 212a are the same length.

The length of the antenna affects the wavelength length of a signal to be transmitted and received (resonance frequency signal), and a slot-like antenna like the antenna of the present invention can have a length of a quarter wavelength (? / 4) of the resonance frequency . Since the length of the antenna is proportional to the wavelength length of the resonance frequency, the length of the first antenna (Ant.1) is longer than the length of the second antenna (Ant.2), so that the first antenna (Ant.1) (700 to 950 MHz), and the second antenna (Ant.2) can be used as an antenna for transmitting and receiving the second signal (1650 to 2.3 GHz) of the medium frequency.

The first conductive member 211 is composed of a first portion 211a located on the first side and a second portion 211b located on the second side and is arranged in an L shape at the corner of the mobile terminal 100 do. The end of the second portion 211b is connected to the metal frame 107 and the end of the first portion 211a is kept apart from the metal frame 107 to constitute a slot antenna.

The length of the second portion 211b may be longer than the length of the first portion 211a in order to arrange the first portion 211a so as not to overlap with the display flexible substrate 1515 ₁ ). If so the slot is extended to above because users may be degraded by a hand length (b ₁₎ of the second portion (211b) is suitable to be formed to be about 50mm.

The second antenna (Ant.2) formed by the second conductive member (212) transmits and receives the mid-frequency signal. The length of the fourth portion (212b) is shorter than the first conductive member (211) b ₂₎ is smaller than the length (b ₁₎ of the second portion (211b). The wavelength length ratio of the first signal and the second signal is proportional to the length (d + b1) of the first conductive member 211 and the length (d + b2) of the second conductive member 212. More precisely proportional to the length of the wavelength, including the length of the grounding line 235 connected to the first conductive member 211 and the second conductive member 212.

For example, the ratio of the wavelengths of the first signal and the second signal is about 2: 1, the length of the second portion 211b is 50 mm, the length of the first portion 211a and the third portion 212a is 15 mm The length of the fourth portion 212b may be 17 mm

5 is a diagram showing the currents flowing through the feeders 231 and 232 of the first antenna Ant.1 and the second antenna Ant.2 of the mobile terminal 100 of the present invention. The positions of the feeding parts 231 and 232 can be arranged in consideration of the frequency characteristics, the position of peripheral devices, and the like.

As shown in FIG. 2, when power is applied to the conductive member located at the lower end, the flow of current in the metal frame 107 appears only in the vertical direction. Since the first antenna Ant.1 of the mobile terminal 100 of the present invention is located in the lateral direction of the mobile terminal 100, the power of the first antenna Ant.1 is supplied from the first feeder 231 The feed line 231 'may be connected to the second portion 211b of the first conductive member 211. 5, when the feed line 231 'is connected to the second portion 211b located on the side of the mobile terminal 100, the flow of the current flows in the horizontal direction and in the vertical direction The flow of

In order to provide a space for mounting the battery 191, the main board 181 of the present invention may be arranged such that the middle portion of the main board 181 is biased to a portion adjacent to the first conductive member 211, . That is, the main board 181 may have a U-shape and the main board 181 located at the lower end may be mounted with many components such as the interface unit 160, the speaker 152b, and the microphone 122, RFIC (Radio Frequency IC, first power feeder 231) may be disposed at an intermediate portion located at a side portion of the antenna. The distance between the position where the RFIC and the feed line 231 'are connected to the first conductive member 211 is not long when the feed line 231' is connected to the side of the mobile terminal 100, Can be freely adjusted. That is, the tuning of the antenna in the low frequency band is easy, and the bandwidth in the low frequency band can be improved.

The second conductive member 212 may also include a second power feeder 232 for supplying power and a power feed line 232 'connected to the first power feeder 231 or the second power feeder 232, Can directly supply power to the first conductive member 211 and can supply power by a coupling method even if it is not directly connected.

FIG. 6 is a graph showing the polarizations of the electromagnetic waves formed by the antennas of the conventional mobile terminal 100 of FIG. 2, and FIG. 7 is a graph showing the polarizations of the electromagnetic waves formed by the antennas of the mobile terminal 100 of FIG. FIG. 4 is a graph showing polarization. FIG.

6 and 7 are diagrams showing the power of Theta and Phi in the spherical coordinate system. When power is supplied to the lower part of the mobile terminal 100, the maximum points in theta are non-uniform and power is supplied to the side of the mobile terminal 100 Theta value forms a uniform pattern (Fig. 6 (a) and Fig. 7 (a)).

Also, it can be seen that the level of Phi is lower than that in the case of supplying power to the side of the mobile terminal 100 when power is supplied to the lower part of the mobile terminal 100 (FIG. 6 (b) and FIG. 7 b)).

When the power is supplied to the side surface of the mobile terminal 100, since the power of theta and phi are equal to each other, the radiation is uniformly displayed in any direction. Thus, the mobile terminal 100 can perform wireless communication performance regardless of the tilting direction .

8 is a view showing an embodiment of a mobile terminal 100 including a third slit 223, in which a third slit 223 is further formed in the lateral direction, unlike the side case 200 shown in Fig. 5 . The third conductive member 214 separates the first conductive member 211 and the fourth conductive member 214 with the third slit 223 and is connected to the metal frame 107 and the first conductive member 211 Is connected to a ground line 235 which connects the first conductive member 211 and the ground and is grounded, adjacent to the third slit 223. The ground line 325 may be connected to the metal frame 107 or through the main board.

Since the metal frame 107 serves as a ground plane in the mobile terminal 100, in the embodiment shown in FIG. 5, the first conductive member 211 has the same effect as that of the portion where the portion connected to the metal frame 107 is grounded . However, in the embodiment in which the metal frame 107 and the first conductive member 211 are integrally formed, the grounding position of the first antenna Ant.1 can not be adjusted, thereby limiting antenna design.

On the other hand, in this embodiment, since the ground line 235 is formed using the conductive thin film formed on the substrate, it is advantageous that the shape, arrangement and length can be adjusted freely.

 FIG. 9 is a view showing an electromagnetic field (E-field) formed by the antenna of FIG. 5 and the antenna of FIG. As compared with the case where the third slit 223 does not exist on the side surface of the mobile terminal 100 as shown in FIG. 9A, when the third slit 223 exists as shown in FIG. 9B, the electromagnetic field spreads more widely have. In the case of dispersing the electromagnetic field, it is possible to prevent a decrease in performance even if the user grasps the mobile terminal 100 with a hand effect, that is, a hand effect in which communication performance is lowered when the user holds the mobile terminal 100 by hand.

10 is a graph showing characteristics of the antenna of Fig. 5 and the antenna of Fig. 8. Fig. Compared to an embodiment (w / o side slit) that does not include the third slit 223 in the case of forming the third slit 223 (w / side slit), the bandwidth of the low frequency band is slightly wider, There is an effect of increasing.

11 is a view showing a modification of the embodiment of Fig. 8 and a graph showing the characteristics of the antenna. The resonance frequency can be tuned by adjusting the length of the ground line 235. A ground line can be adjusted in length of 235, and the first conductive member 211, the ground line 235 is the sum of the length so as to correspond to a quarter wavelength (λ _1/4) of said first signal.

When the space in which the ground line can be arranged is limited, the ground line 235 may be arranged to be folded as shown in FIG. 11 (a). When the length of the ground line 235 is increased, the resonance frequency is lowered because the wavelength length of the resonance frequency becomes longer as shown in FIG. 11 (b).

Fig. 12 is a diagram showing an embodiment in which a switch 240 is added in the embodiment of Fig. 5 and an embodiment in which a switch 240 is added in the embodiment of Fig. 8, and Fig. 13 is a diagram FIG. The presence or absence of the third slit 223 also affects the position of the switch 240 for changing the frequency of the antenna.

The switch 240 of the antenna is connected to the antenna and selectively connects the circuit to change the resonant frequency of the circuit. And a tuning element formed on the main substrate 181. The switching can selectively change the frequency within a predetermined range by connecting several tuning elements. The tuning element includes an inductor, a capacitor or a resistor, and the end is connected to the ground.

In order to change the resonance frequency band within a range of several tens MHz so that the communication service of another region or another carrier can be used in one terminal, 240).

Since the switch 240 adjusts the resonance frequency by changing the current flow of the antenna, it is easy to change the resonance frequency only at the end of the antenna. However, if the open end portion (the portion of the first portion 211a adjacent to the first slit 221) is open, there is a problem that the open portion is grounded, (I.e., a portion connected to the base 107).

As shown in FIG. 12 (a), a portion connected to the metal frame 107 without the third slit 223 on the side surface of the mobile terminal 100 has the same effect as that of grounding the antenna. Even if the switch 240 is connected to a position adjacent to the end of the second portion 211b coupled with the metal frame 107, there is a problem that the effect of switching is insignificant because current flows to the portion connected to the metal frame 107. [

Therefore, in this case, the switch 240 is disposed closer to the open end of the first portion 211a than the feed line 231 ', and the switch 240 is adjacent to the feed line 231' The switch 240 is disposed at a certain distance from the feed line 231 '.

When the third slit 223 is provided on the side surface of the mobile terminal 100 as shown in Figure 12B, the first conductive member 211 is not directly connected to the metal frame 107 but connected to the ground line 235 Lt; / RTI > As described above, when the antenna is grounded using the ground line 235, it is advantageous to tune the antenna, and the switch 240 can be disposed on the ground line 235. [ By arranging the switch 240 on the ground line 235, the frequency can be changed more easily than in FIG. 12A by changing the ground line 235 to tune the frequency.

Fig. 13 (a) shows the efficiency of the antenna of Fig. 12 (a), and Fig. 13 (b) shows the efficiency of the antenna of Fig. 12 (b). In FIG. 13 (a), the resonance frequency is shifted according to the switching, but the efficiency tuning effect is weak due to the shifted resonance frequency. In the case of FIG. 13 (b) The balance of antenna efficiency with switching is improved.

FIG. 14 is a diagram showing an embodiment in which the third antenna Ant.3 is added in the embodiment of FIG. Recently, mobile communication has a plurality of antennas in a mid-frequency band and a high-frequency band for transmission and reception of a large amount of data and stable communication. The first antenna Ant.1 transmits and receives a first signal of a low frequency band and the second antenna Ant.2 transmits and receives a second signal of a middle frequency band shorter than the first antenna Ant.1 It can be used as a main antenna.

It is not possible to use signals of various frequency bands with only two antennas, so that an additional antenna can be realized. An antenna for transmitting and receiving a signal of a high frequency band by further connecting a conductive pattern to the feed line of the second antenna Ant.2 can be further implemented. The conductive pattern 1111 does not affect the radiation of the conductive pattern 1111 because the third conductive member 213 is not used as an antenna even when the conductive pattern 1111 overlaps with the third conductive member 213. [

Also, a third antenna (Ant.3) may be implemented which forms a radiation pattern adjacent to a lower end portion of the mobile terminal 100 and independently operates by supplying power to the radiation pattern. The radiation pattern may be a conductive pattern formed on the main substrate 181 or a conductive pattern formed on the inner surface of the rear case 102. The conductive pattern may be grounded and supplied with power to be used as an antenna. Since the third antenna (Ant.3) is short in length, it can be used as a sub-antenna for transmitting a signal in a high frequency band.

The resonance frequency length can be adjusted by further connecting a stub 1114 to the end of the first conductive member 211 as shown in FIG. When the length of the stub 1114 is increased by 10 mm, the resonant frequency can be shifted to a low frequency of 80 MHz. The stub 1114 may be formed on the main board or on the inner side of the rear case. The first conductive member 211, the stubs 1114 and the sum of the length by adjusting the length of the stub 1114 so as to correspond to a quarter wavelength (λ _1/4) of the first signal to tune a first signal have.

FIGS. 15 and 16 are diagrams showing an embodiment in which the third antenna Ant.3 is added in the embodiment of FIG. A part of the fourth conductive member 214 of the side case 200 partitioned by the third slit 223 is spaced apart from the metal frame 107 so that the fourth conductive member 214 and the metal frame 107 can transmit and receive signals.

When power is supplied to the first antenna (Ant.1) due to the fourth conductive member (214), it is possible to transmit and receive not only a signal of a low frequency band but also a signal of an intermediate frequency band or a high frequency band. If the length of the fourth conductive member 214 is long, a signal in the high frequency band can be transmitted / received if the signal in the mid-frequency band is short.

That is, the first antenna (Ant.1) may serve as a sub-antenna of a mid-frequency band or a high-frequency band. In this case, the role of the third antenna Ant.3 may overlap with that of the third antenna Ant.3 so that the third antenna Ant.3 can be omitted.

As shown in FIG. 16, the third conductive member 214 may be used as a third antenna (Ant.3) for transmitting and receiving a third signal by connecting a separate feed line 233 '. Because achieve a slot antenna, and the fourth conductive member 214 from the portion coupled to the metal frame 107 and the third slit 223. The length is a third quarter-wavelength (λ _3/4) of the signal to the Or less.

When the fourth conductive member 214 is used as the third antenna Ant.3, the first antenna Ant.1 is the main antenna of the low frequency signal and the second antenna Ant.2 is the main antenna of the middle frequency band. The third antenna Ant.3 can serve as a main antenna in a high frequency band. According to circumstances, the second antenna Ant.2 can serve as a sub-antenna of a high frequency band and the third antenna Ant.3 can serve as a sub-antenna of a mid-frequency band at the same time.

17 is a view showing driving of the antenna along with the hand of the user holding the mobile terminal 100. Fig. 18 is a view showing an example in which the first antenna Ant.1 and the second antenna Ant.2 can be selectively used Fig.

When the user holds the mobile terminal 100 by hand, the hand reaches the side case 200. When the user's hand touches the side case 200, current flows and the antenna performance deteriorates (hand effect), so that the resonance frequency is distorted and the performance is degraded. 17, when the palm of the thumb is in close contact with the side case 200 and is gripped with the left hand, the performance of the first antenna Ant.1 positioned on the left side of the terminal deteriorates, The performance of the second antenna Ant.2 located on the right side of the terminal is degraded.

The present embodiment transmits a first signal (low-frequency signal) through a normally operating antenna when one of the first antenna Ant.1 and the second antenna Ant.2 is affected by the performance of the user's hand So that the wireless communication performance can be maintained. 18 shows a metal frame 107 and a side case 200 viewed from the front of the mobile terminal 100. The left side is the first antenna Ant.1 and the right side is the second antenna Ant.2. The second antenna Ant.2 may extend the fourth portion 212b in a length corresponding to the length of the first antenna Ant.1 in order to transmit and receive the second signal as well as the first signal. The fourth portion 212b may be directly connected to the metal frame 107 and may be grounded via the ground line 235 without being directly connected to the metal frame 107 by the fourth slit as shown in Fig. have.

The first antenna (Ant. 1) may include a first switch (241) located at the ground line (235). The first switch 241 is connected to a tuning circuit for finely tuning the first signal as described above. When the performance of the first antenna Ant.1 is bad, the first switch 241 is opened, It is possible to control the conductive member 211 from functioning as an antenna.

The second antenna Ant.2 has a second switch 242 at a position corresponding to the portion where the second conductive member 212 is connected to the metal frame 107 in the embodiment of Fig. 8 separately from the ground line 235 . When the second antenna 24 transmits and receives a second signal by disposing the second switch 242 at a position corresponding to the wavelength length of the second signal to transmit and receive the second signal, the second antenna 24 transmits the second signal 242 The antenna length can be shortened.

A first switch 231 for supplying power to the first antenna Ant.1 and a changeover switch 243 connected to the second antenna Ant.2 for supplying power to the second antenna Ant.2 The antenna arrangement can be reconfigured according to the manner in which the user holds the mobile terminal 100. [

The first antenna (Ant.1) transmits and receives a first signal in a low frequency band, and the second antenna (Ant. 2 can transmit and receive the second signal in the mid-frequency band. The first switch 241 connected to the first antenna Ant.1 may be connected to an appropriate tuning circuit for frequency tuning to match the first low-frequency signal transmitted and received by the first antenna Ant.1. The second switch 242 closes and shortens the second antenna Ant.2 to transmit and receive the second signal so that the length of the second antenna Ant.2 corresponds to a quarter of the wavelength length of the second signal . The stub 1114 may be formed in addition to the second antenna Ant.2 to serve as an antenna for transmitting and receiving a high frequency third signal.

When the user holds the mobile terminal 100 with the right hand as shown in (a) of FIG. 17 (right hand), the second conductive member 212 of the second antenna Ant.2 touches the user's hand, It can not serve as an antenna for transmitting and receiving data. So that both the first signal and the second signal can be transmitted and received through the first antenna Ant.1. The first conductive member 211 transmits and receives the first signal and the fourth conductive member 214, which is divided by the third slit 223, can resonate in the second signal.

When the user holds the mobile terminal 100 with the left hand as shown in FIG. 17B (left hand), the first conductive member 211 of the first antenna Ant.1 touches the user's hand, It is possible to control the changeover switch 243 to transmit and receive the first signal from the second antenna Ant.2. The first switch 241 may be opened to transmit and receive the first signal by blocking the first conductive member 211 from functioning as an antenna and controlling the second switch 242 connected to the second conductive member 212 . The second conductive member 212 transmits and receives the first signal so that the fourth conductive member 214 can transmit and receive the second signal to compensate for the antenna performance degradation caused by the user's hand.

The touch of the user's hand can be detected using the touch sensor, or when the performance of the specific signal is deteriorated, the user's hand is touched, and the antenna can be reconfigured in an optimal combination by switching.

19 is a view showing another embodiment of the antenna of the present invention. However, in order to secure a mounting space due to an increase in the number of antennas, the upper conductive member may be extended in the left and right directions as in the above-described embodiment Thereby increasing the number of upper antennas.

The fifth conductive member can be extended in the lateral direction so that the fourth antenna transmits and receives the first signal having a low frequency and the number of antennas can be increased by additionally adding a stub 1114 or a conductive pattern.

A notch 1517 may be formed so that a camera, various sensors, a receiver, and the like are positioned by cutting a part of the display unit 151 as shown in FIG. Since the electronic parts are mounted on the notched portion 1517, if the end portions of the conductive members are overlapped and disposed, the antenna performance may be affected. As a result, the fifth conductive member, the sixth conductive member, The fifth slit and the fourth slit that divide the second slit 1511 can be positioned outside the notch 1517. [

The touch sensor flexible substrate for connecting the touch sensor disposed on the front surface of the display unit 151 and the main substrate 181 may be located at an upper portion to avoid overlap with the display flexible substrate 1515. In this case, It is possible to improve the antenna performance by disposing the sensor flexible substrate and the slit so as not to overlap each other.

As described above, the mobile terminal 100 according to the present invention can secure the antenna performance by disposing the antenna using the side case 200 on the side of the mobile terminal 100, thereby reducing the size of the upper and lower bezels. In addition, the antennas are arranged symmetrically on both the left and right sides to improve the wireless communication performance degraded by the user's hand.

The foregoing detailed description should not be construed in all aspects as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
