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 or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in an inner region of the mobile terminal covered by the touch screen described above or near the touch screen.

Examples of the proximity sensor 141 include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object by the change of the electric field according to the proximity of the conductive object. 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, an action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching an object on a screen is called a "contact touch." The position at which the object is in close proximity touch on the touch screen means a position where the object is perpendicular to the touch screen when the object is in close proximity touch.

Here, the touch object is an object applying a touch to the touch sensor and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

As such, 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 then transmits the corresponding data to the controller 180. As a result, the controller 180 can know which area of the display unit 151 is touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different control or perform the same control according to the type of touch object that touches the touch screen (or a touch key provided in addition to the touch screen).

The photo sensor may be stacked on the display element, which is configured to scan the movement of the sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column to scan contents loaded on the photo sensor by using an electrical signal that changes according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of light change, and thus, the position information of the sensing object can be obtained.

Although related to a particular type of mobile terminal, a description of a particular type of mobile terminal may generally apply to other types of mobile terminals.

Herein, the terminal body may be understood as a concept that refers to the mobile terminal 100 as at least one aggregate.

The mobile terminal 100 includes a case (eg, a frame, a housing, a cover, etc.) forming an external 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 internal space formed by the combination of the front case 101 and the rear case 102. At least one middle case may be additionally disposed between the front case 101 and the rear case 102.

As the multimedia functions are expanded, the size of the display unit 151 increases, and the size of the bezel positioned around the display unit 151 becomes smaller. In particular, the upper portion of the camera 121, the sound output unit 152, the proximity sensor 141, etc. need to secure a space for positioning, and the lower portion of the physical button is disposed to limit the size of the display unit 151.

However, recently, by minimizing the size of each component and implementing the user input unit 123 using soft keys instead of physical buttons, the soft keys are outputted only when necessary and disappear when unnecessary, thereby increasing the size of the screen.

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

The cases 101, 102, and 103 may be formed by injecting a synthetic resin, or may be formed of a metal, for example, stainless steel (STS), aluminum (Al), titanium (Ti), or the like.

A sound hole for emitting sound generated from the first sound output unit 152a may be formed in the window 151a of the display unit 151. However, the present invention is not limited thereto, and the sound may be configured to be emitted along an assembly gap between the structures (for example, a gap between the window 151a and the front case 101). In this case, an externally formed hole may be invisible or hidden for sound output, thereby simplifying the appearance of the mobile terminal 100.

The light output unit 154 is configured to output light for notifying when an event occurs. Examples of the event may include message reception, call signal reception, missed call, alarm, schedule notification, email reception, information reception through an application, and the like. When the user's event confirmation is detected, the controller 180 may control the light output unit 154 to end the light output.

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

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

In the drawing, the first operation unit 123a is illustrated as being a touch key, but the present invention is not limited thereto. For example, the first manipulation unit 123a may be a mechanical key or a combination of a touch key and a push key.

The contents input by the first and second manipulation units 123a and 123b may be variously set. For example, the first operation unit 123a receives a command such as a menu, a home key, a cancellation, a search, etc., and the second operation unit 123b is output from the first or second sound output units 152a and 152b. The user may receive a command such as adjusting the volume of the sound and switching to the touch recognition mode of the display unit 151.

Meanwhile, as another example of the user input unit 123, the rear input unit 123c may be provided on the rear surface of the terminal body. The rear input unit 123c is manipulated to receive a command for controlling the operation of the mobile terminal 100, and the input content may be variously set. For example, commands such as power on / off, start, end, scroll, etc., control of the volume of sound output from the first and second sound output units 152a and 152b, and the touch recognition mode of the display unit 151. Commands such as switching can be received. The rear input unit 123c may be implemented in a form capable of input by a touch input, a push input, or a combination thereof.

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

As such, when the rear input unit 123c is provided at the rear of the terminal body, a new type user interface using the same may be implemented. In addition, when the touch screen or the rear input unit described above replaces at least some functions of the first operation unit 123a provided in the front of the terminal body, the first operation unit 123a is not disposed on the front of the terminal body. The display unit 151 may be configured with a larger screen.

Meanwhile, the mobile terminal 100 may be provided with a fingerprint recognition sensor for recognizing a user's fingerprint, and the controller 180 may use fingerprint information detected through the fingerprint recognition sensor as an authentication means.

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 format. Such a camera may be referred to as an 'array camera'.

The terminal body may be provided with at least one antenna for wireless communication. The antenna may be built in the terminal body or formed in the case. For example, an antenna that forms part of the broadcast receiving module 111 (refer to FIG. 1A) may be configured to be pulled out from the terminal body. Alternatively, the antenna may be formed in a film type and attached to the inner side of the rear cover 103, or may be configured such that a case including a conductive material functions as an antenna.

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

As the multimedia functions become more important, the wireless communication technology performed by the mobile terminal 100 is performed in various forms such as short distance, long distance, or between devices. Since different frequency bands (resonant frequencies) are used, different antenna radiators are used. Should be.

In order to support the transmission and reception of large-capacity data, a fifth-generation mobile communication technology capable of transmitting and receiving large-capacity data rapidly is being developed, in addition to LTE, a fourth-generation mobile communication technology, using a very high-frequency millimeter wave. Fifth generation mobile communication technology uses ultra-high frequency signals. Wireless technology for 5G mobile communication is called NR (New Radio) in the 3rd Generation Partnership Project (3GPP), and International Telecommunications Union (ITU) is called International Mobile Telecommunication (IMT-20-2020). It is a communication method implemented by the method.

In addition to transmitting fast and large amounts of data through 5G mobile communication, the reliability of data transmission may be improved and a function of supporting IoT may be added according to the spread of the Internet of Things (IOT).

5G is a mobile communication technology with a maximum download speed of 20Gbps and a minimum download speed of 100Mbps. In addition, the Internet of Things (IoT) service can be provided to a million devices within a 1㎢ radius, and free communication is possible even at a high speed train of 500 km per hour. The download speed is 280 times faster than LTE. It is a wireless communication technology that can download a 1GB movie in 10 seconds.

5G mobile communication has noticeably improved response speed as well as transmission speed. If the data transfer rate is an indicator of how much data can pass through at one time, the response rate determines how long it takes for small data to travel.

At 4G, the response speed is up to 10-50ms (milliseconds, milliseconds). At 5G, this response is about 10 times faster. Thanks to this, 5G will be actively introduced in the fields of autonomous vehicles and the Internet of Things (IoT), where a large amount of data must be seamlessly exchanged with a central server.

Frequency bands of the centimeter wave (3 GHz to 30 GHz) and the millimeter wave (30 GHz to 300 GHz) may be used, and a communication method using a signal of a frequency band below 6 GHz is particularly called Sub-6.

Sub-6 includes N41 using the signal band of 2.5GHz to 2.7GHz and N78 using the signal band of 3.3GHz and 3.8GHz and below, and the frequency band used may vary from country to country.

2 is a view showing the arrangement of the conventional antenna module 300, Figure 3 is a cross-sectional view showing a laminated structure of the antenna module 300 of FIG. Conventionally, a wireless communication module using a centimeter wave and a wireless communication module using a millimeter wave are independently provided. For convenience of explanation, the centimeter wave is called a first signal and the millimeter wave is called a second signal.

Since the first signal has a length of several centimeters, an antenna such as a PIFA antenna or a slot antenna may be used. The antenna may be implemented using a conductor having a length of 1/4 or 1/2 of the first signal wavelength, and a metal side case 210 positioned on the side of the mobile terminal 100 may be used. .

Currently, not only 5G mobile communication but also an existing antenna for 4G mobile communication (LTE) should be provided together. When using the side case 210, the slit 215 is added to the side case 210 to be used as an antenna. Add intervals. In this case, the number of slits 215 increases to affect the appearance of the mobile terminal 100, thereby limiting the design. Further, when the section used as the antenna of the side case 210 increases, the mobile terminal 100 increases. The antenna radiator is also disposed on the left and right side portions, and when the user grasps the mobile terminal 100, the antenna radiator may reach the antenna radiator to deteriorate wireless communication performance.

In the frequency signal band used in 5G, the second signal uses a signal in a frequency band of 28 GHz or more, and the length of the wavelength becomes very small considering that the high frequency band used in LTE communication is 2.5 GHz. As the length of the wavelength is shortened in mm, the size of the antenna radiator may be reduced.

By using signals in the ultra high frequency band, interference with other signals can be reduced, thereby widening the frequency band, thereby improving antenna performance. In addition, the size of the antenna radiator for the signal of the ultra-high frequency band can be reduced, and if the array antenna is implemented by placing multiple antenna patches on a substrate made of an insulating material, the direction of radiation can be adjusted in a specific direction, and the antenna performance is more than 10 times. It can increase.

Conventional antennas used a form such as a dipole antenna or a monopole antenna, and this form can be radiated omnidirectionally because it is not directional, but when radiating for a high frequency signal such as the present invention, more energy is consumed. It is advantageous to use an array antenna to emit the beam in a particular direction.

That is, the second antenna 325 for the second signal may use square or circular conductive patches spaced at predetermined intervals, and the size or spacing of the conductive patches may be set based on the length of the second signal wavelength.

The second antenna 325 for transmitting the second signal and the second wireless communication unit 322 for controlling the second antenna 325 may be configured as one antenna module 300. As shown in FIG. 3, an antenna substrate 301 on which the second wireless communication unit 322 and the second antenna 325 are mounted may be included. An auxiliary substrate is mounted on the IC mounted on the main board 181 to add the antenna module 300 to the main board 181 on which an integrated circuit (IC) for controlling each component of the mobile terminal 100 is mounted. The antenna module 300 may be mounted thereon. The auxiliary substrate may be implemented in a bridge form to implement a separation distance from the IC mounted on the main substrate 181 so that the auxiliary substrate does not directly contact the IC.

As shown in FIG. 3A, the antenna module 300 includes a second antenna 325 and a second wireless communication unit 322 embedded in the antenna substrate 301 to transmit and receive a second signal. The 322 and the second antenna 325 may be packaged. The second antenna 325 is formed on the substrate in the form of a thin metal foil in the form of a conductive patch. When the second antenna 325 is exposed to the outside, the second antenna 325 may be broken and embedded in the substrate.

The second wireless communication unit 322 receives power from a power management integrated chip (PMIC) corresponding to the second signal in order to transmit and receive the second signal through the second antenna 325 (conductive patch). The patch can be powered on.

However, in the conventional structure, the auxiliary substrate must be additionally provided to mount the antenna module on the main board, and the number of processes is increased to mount the auxiliary board and the antenna module by SMT (surface mounter technology), respectively, and FIG. There is a problem that the thickness is increased even in the assembled state. Accordingly, the present invention provides an antenna module 300 having a form in which an auxiliary substrate may be omitted and further including a first antenna 315 to solve the above problems.

4 and 5 are a plan view and a cross-sectional view showing an embodiment of the antenna module 300 of the present invention. The antenna module 300 of the present invention may include not only the second antenna 325 but also the first antenna 315 for transmitting and receiving the signal of the centimeter wave. The second antenna 325 may be implemented in a form in which a plurality of conductive patches are spaced apart at predetermined intervals, but the first antenna 315 may be implemented in the form of a conductive pattern 315 corresponding to one quarter of the wavelength length. .

The conductive pattern 315 of the present invention replaces the first antenna 315 implemented using the side case 210 in the conventional mobile terminal 100 of FIGS. 2 and 3. When the side case 210 is not used as an antenna, the side case 210 does not need to have an additional slit 215 as shown in FIG. 2, and the antenna module 300 may include the first antenna 315. As a result, the first wireless communication unit 312 may not necessarily be located at the end of the mobile terminal 100 and may be more freely disposed.

As shown in FIG. 5A, the first antenna 315 may be formed on the surface of the antenna substrate 301, and may be formed inside the antenna substrate 301 like the second antenna 325. can do. The antenna substrate 301 may be formed by stacking a plurality of insulating layers, and the first antenna 315 and the second antenna 325, that is, the conductive pattern 315 and the conductive patch may be formed on different layers. .

When the centimeter wave uses two or more frequency bands (for example, N41 (2.6 GHz) and N78 (3.5 GHz)), the centimeter wave may include a plurality of conductive patterns 315 having different lengths according to the wavelength length of each frequency band.

The first wireless communication unit 312 may be mounted on the antenna module 300 as well, but the antenna module 300 may be directly mounted on the main board 181 due to a problem in that the volume of the antenna module is too large. The first antenna 315 may be used as an antenna for WIFI. Since WIFI uses a 2.5 GHz band, the wavelength of the first signal is similar to that of the first signal, so that one antenna can be shared.

In order to reduce mutual interference, a third wireless communication unit 332 which performs WIFI wireless communication, a switch 317 which selectively connects the first wireless communication unit 312 and the conductive pattern 315 may be further provided. The switch 317 may connect the first antenna 315 to the third wireless communication unit 332 when using WIFI and the first wireless communication unit 312 when using mobile communication.

The third wireless communication unit 332 may be mounted on the main board 181, but may also be mounted on the antenna module 300 as shown in FIG. 5. As described above, the antenna module 300 may include an IC and an antenna mounted on the antenna substrate 301, and one surface thereof may face the main substrate 181, and the other surface thereof may face the rear surface of the mobile terminal 100. have.

The other direction toward the rear surface of the mobile terminal 100 is a direction in which electromagnetic waves are radiated from the first antenna 315 and the second antenna 325 such as the conductive pattern 315 or the conductive patch, and when the IC 183 is mounted, As it may affect the signal performance, it may be disposed in one surface direction than the conductive pattern 315 or the conductive patch 325. The second wireless communication unit 322 or the switch 317 may be implemented in a form embedded in the antenna substrate 301, and the IC 183 on one surface facing the main board 181 to further secure the mounting space. Can be implemented.

An IC may be mounted on one surface of the antenna substrate 301 by using a cavity substrate in which one surface of the antenna substrate 301 is partially recessed. As shown in FIG. 5, the antenna substrate 301 used in the antenna module 300 of the present invention may enlarge the number of components that can be mounted in the antenna module 300 using a cavity substrate.

In addition, one surface of the antenna substrate 301 faces the main substrate 181 so that the main substrate 181 and the antenna substrate 301 of the antenna substrate 301 may be discharged to release heat generated from an IC mounted on one surface of the antenna substrate 301. It may further include a heat radiation member 305 interposed between the IC mounted on one surface.

As described above, the antenna module 300 according to the present invention can implement the antenna for the millimeter wave and the antenna for the centimeter wave in one antenna substrate 301 can reduce the manufacturing cost.

In addition, since the antenna for the centimeter wave can be implemented without using the side case 210, there is no need to additionally form the slit 215, and there is a need for tuning to cause interference with the LTE antenna or to resonate in two or more bands. No antenna is easy to implement.

The above detailed description should not be construed as limiting in all respects but should be considered as illustrative. The scope of the present invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.
