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 fluorescent light sensor, a mirror reflection fluorescent light 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 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 senses 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, do.

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.

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 side member 205 may include a metallic material. In consideration of a design aspect, it is preferable to form a continuous side surface. However, considering the performance of the antenna, the side member 205 may be partially opened or a non- .

The side member 205 itself can be used as an antenna radiator in order to provide various antennas that meet the needs of various communication companies. When the side member 205 itself is used as the antenna radiator, it is possible to prevent the signal from being disturbed by the metal material (the side member 205) located outside. The existing parts can be used as they are, and the antenna radiator can be secured without increasing the size of the mobile terminal 100. [

The distance a between the base plate 230 of the present invention and the first side member 210 and the second side member 220 can be set to 1.5 mm or more and 2.5 mm or less. If it is 1.5 mm or less, there is a problem that the performance is deteriorated.

Referring to FIG. 3, a display unit 151 positioned on the front surface of the mobile terminal 100 is seated on the metal frame 200. Since the display unit 151 includes a plurality of transistors and the touch sensor overlapped with the display unit 151 is formed of a transparent electrode such as ITO, the conductive member is closely arranged.

When the left and right sides of the display unit 151 are spaced apart from each other by at least 1.5 mm, the left and right sides of the display unit 151 are spaced apart from the first side member 210 and the second side member 220 by a predetermined distance. The space c between the display unit 151 and the first side member 210 and the second side member 220 may be in a range between the base plate 230 and the first side member 210 Can be arranged narrower than the interval (a).

The position of the slit 235 is located at a short first side of the mobile terminal 100 and does not reach the user's hand. The antenna radiation effect is maximized at the portion of the slit 235, so that when the slit 235 is covered with a hand or a conductive material, the antenna characteristics are changed to deteriorate the performance. However, as in the present invention, Is positioned at the lower end of the terminal body, it is possible to prevent the antenna performance from being degraded even if the user hands the body during the call.

When the user holds the terminal body, there is a tendency to support the lower corner portion of the terminal body with the palm of the hand. When the slit 235 is too close to the corner of the mobile terminal 100, It can be disposed at a position spaced apart from the second corner 223 by a predetermined distance d. For example, it is preferable to dispose the antenna at a distance of about 16 mm from the third side of the terminal body.

The other end of the first side member 210 and the other end of the second side member 220 are connected to the base plate 230, respectively. A portion of the first side member 210 and the second side member 220 except for the other end is spaced apart from the base plate 230. Since the base plate 230 functions as a ground, when power is applied to the first side member 210 and the second side member 220, signals can be transmitted and received in the form of an inverted F antenna (IFA: Inverted F Antenna) have.

FIG. 4 is a conceptual view of a mobile terminal 100 for explaining an antenna structure according to an embodiment of the present invention. Referring to FIG. 4, a first conductive pattern 241 for supplying power to a first side member 210, And a second conductive pattern 242 that supplies power to the second conductive pattern 220. Hereinafter, an antenna operated by the first side member 210 and the first conductive pattern 241 is referred to as a first antenna structure, and an antenna operated by the second side member 220 and the second conductive pattern 242 2 antenna structure.

The first side member 210 and the second side member 220 may be electrically connected to the first side pattern 210 and the first conductive pattern 241 formed on the main substrate using a connecting member such as a C clip .

The first side member 210 and the second side member 220 have different lengths so that the slit 235 is disposed biased toward the third side from the center of the first side as shown in FIG. Since the lengths of the first side member 210 and the second side member 220 are different, signals of different frequency bands are transmitted and received with different resonance frequencies.

The wavelength length of the resonance frequency is determined according to the length of the antenna radiator, and a longer length of the antenna radiator has a lower resonance frequency. Therefore, the first antenna structure including the first side member 210 having a long length transmits / receives a signal of a low frequency band, and the second antenna structure including the second side member 220 has a relatively high frequency band, Band signals.

For example, the first antenna structure transmits and receives signals of B5 (850 MHz) and B8 (900 MHz), and the second antenna structure transmits signals of B2 (1900 MHz), B3 (1750 to 1765 MHz) and B3 (1765 to 1780 MHz) Send and receive. Since a signal of a high frequency band of 2 GHz or more has a short wavelength, a signal of a high frequency band such as B7 (2600 MHz) can be transmitted / received by adding a short antenna pattern.

It may have a different resonant frequency depending on the length of the inverted-F antenna, the connection point of the conductive pattern supplied with power, and the ground point (the position connected to the base plate 230). If the first side member 210 and the second side member 220 are too close to the base plate 230, there is a problem that wireless communication performance is deteriorated. If the first side member 210 and the second side member 220 are too far apart, have. Particularly, when the distance between the first side member 210 of the first antenna structure for transmitting / receiving a signal of a low frequency band and the base plate 230 is shortened, the performance deteriorates severely.

As the size of the mobile terminal 100 is reduced and the size of the display unit 151 is increased by minimizing the size of the bezel (its periphery except the output area of the display on the front face), the performance of the inverted F antenna is deteriorated (In particular, a decrease in performance occurs in a low frequency band), and is also utilized as a slot antenna in order to reinforce this.

The slot antenna may be used as an antenna by making a long slot formed between the ground and the antenna radiator and supplying power to the slot. The slot antenna is advantageous in that it is closer to the base plate 230 than the inverted F antenna.

In addition, since the slot antenna emits radiation through the ground, that is, the base plate 230 as well as the radiation in the slot itself, it is advantageous in that it is less influenced by external factors such as holding by hand compared to the PIFA antenna.

FIG. 5A is a conceptual view of a comparative example of a slot antenna, and FIG. 5B is a conceptual view of a slot antenna according to an embodiment of the present invention. 5A, the size of the first radiation area A1 in FIG. 5A is larger than the first radiation area A1 'in FIG. 5B, and in the second radiation area A2 in FIG. 5A and FIG. The size of the second radiation region A2 is the same. In this case, the first radiation region A1 and the first radiation region A1 refer to the radiation region by the antenna pattern (the side member 205), and the second radiation region A2 refers to the radiation region by the ground (the base plate 230) Radiation region.

In Fig. 5A, the first radiation area A1 by the antenna ANT is sufficiently secured and the dependency of the radiation by the first radiation area A1 is high, while in Fig. 5b, the first radiation area A1 ' It is necessary to induce the radiation of the second radiation region A2 due to a decrease in the radiation performance of the antenna ANT. That is, according to an embodiment of the present invention, a part utilized as a ground (GND) can also be utilized as a part of an antenna radiator. However, in one embodiment of the present invention, it does not mean that radiation must always be performed on the ground.

Thus, by expanding the ground (GND) to the radiation space of the antenna pattern, the radiation area can be expanded and the radiation performance can be maximized at a given ground size.

It is important to increase the size of the electric field (e-field) that collects in the slots to boost radiation at the base plate 230. The first side member 210 and the second side member 220 of the present invention surround the first corner 213 and the second corner 223 of the mobile terminal 100 so that the L And is spaced apart from the base plate 230 in a letter shape.

6 schematically illustrates a radiation pattern when power is applied to a first side member 210 according to an embodiment of the present invention through a first conductive pattern 241. A first side member 210 The intensity of the electric field is maximized at the first corner 213 and the base plate 230 of the mobile terminal 100 radiates.

Referring again to FIG. 4, the first side member 210 is powered through the first conductive pattern 241 and the second side member 220 is powered through the second conductive pattern 242. The mobile communication module 112 may control the power feeding part 185 to adjust the power according to signals transmitted and received between the first conductive pattern 241 and the second conductive pattern 242. The first conductive pattern 241 may be located in the middle of the first side member 210 as shown in FIG. 4, and the resonance characteristics change when the position is changed.

The first side member 210 or the second side member 220 may include a switch 183. Only the switch 183 connected to the first side member 210 is shown in the drawing. The switch 183 is an element for varying the resonance frequency, and may be named as a matching module or a matching part for impedance matching.

The switch 183 may be formed of various combinations of a capacitor and an inductor. For example, you can have only inductors of different sizes, inductors and capacitors together, or just one inductor. In addition, the inductor and the variable capacitor may be connected in series, the variable capacitor may be provided, or the inductor and the variable capacitor may be connected in parallel.

The above examples are merely examples, and variable inductors can be used, and a two-contact switch (SPDT) and a three-contact switch (SP3T, single pole triple throw) are also possible. At this time, if the inductor is used, the resonance frequency can be lowered. If a capacitor is used, the resonance frequency can be increased. By appropriately combining the resonance frequency and the resonance frequency, the resonance frequency can be varied.

The first antenna structure of the present invention can be changed in the position where the first conductive pattern 241 is coupled to the first side member 210. [ Referring to FIG. 3, three ribs 214b, 214c and 214d to which the feeding part 185 is connected are shown. One of the ribs 214b, 214c and 214d is selectively provided with a first conductive pattern 241 Can be connected.

A first point 214b, C1 (see FIG. 4) located in the middle of the first side member 210, a second point 214c, 214c located adjacent to the first corner 213 of the first side member 210, C2) (see FIG. 9) and a third point 214d, C3 (see FIG. 12) disposed adjacent to the first end 210a of the first side member 210. Since the frequency bands to be used by mobile communication carriers are slightly different, it is possible to change the connection point of the first conductive pattern 241 to provide a first antenna structure matched to an optimal frequency for each mobile communication service provider.

It is possible to change the feeding position by a switching method and to form different first resonance frequencies by different only the first conductive pattern 241 for each of the operators, without changing the shape of the side member 205 forming the appearance, It can be tailored to the needs of operators.

Hereinafter, the operation and performance of the first antenna structure according to each case in which the first conductive pattern 241 is connected to the first point to the third point C1 to C3 will be described. 4, the first conductive pattern 241 is connected to the first point C1, and FIG. 7 is a graph for explaining the operation and performance of the first antenna structure of FIG. 4 And FIG. 8 is a view for explaining the operation of the first antenna structure of FIG.

The conductive pattern of this embodiment is not located at a straight line distance from the feeding part 185 to the first point C1 of the first side member 210 but extends along the first side member 210 and then bends again, And returns to the point C1. The loop-shaped first feeding part 185 is used for the matching of the resonance frequency and for the implementation of the antenna radiator for transmitting and receiving signals in the high frequency band.

In the case of using the first power feeder 185 of this type, when the power is applied to the first side member 210, the performance as shown in FIG. 7 is obtained. The horizontal axis represents frequency (MHz) and the vertical axis represents frequency performance (dB). The lower the position in the graph, the better the performance at the frequency, which is called the resonance frequency. The resonance frequency of the first side member 210 of the present embodiment largely appears at three frequencies. Resonance occurs at two frequencies in the low frequency band and resonance occurs in the high frequency band.

Referring to FIG. 8, signals are transmitted and received at different frequencies while current flows in three ways. Referring to FIG. 8A, a current flows in an inverted F antenna (IFA: Invented F Antenna) mode. The length of the first side member 210 is related to the wavelength of the resonant frequency and generally resonates at a resonant frequency having a wavelength corresponding to a multiple of the length of the first side member 210.

The length of the first conductive pattern 241 connected to the first side member 210, the connecting position of the first conductive pattern 241 and the conductive material around the first side member 210 and the first side member 210, The resonance frequency can be adjusted by a connected stub or the like.

If necessary, a first stub 246 may be connected to the first end of the first side member 210 to change the resonance frequency. When the first stub 246 is connected, the resonance frequency becomes longer and resonance occurs at a lower frequency. That is, it resonates at a frequency f _low1 having a wavelength four times the total length of the first side member 210 and the first stub 246.

The resonance frequency is determined by the physical length of the first side member 210 and the first stub 246 itself or the length of the first stub 246 and the length of the first side member 210 There may be a difference in the sum of lengths. The first stub 246 may be implemented in the form of an antenna pattern printed on the surface of the antenna carrier 105 or by attaching a separate metal member to the first side member 210.

Also, as shown in FIG. 8 (b), a current flows in a slot antenna mode and is driven in the same manner as a slot antenna to resonate at a frequency having a wavelength of about four times the length of the first slot 215. The slot antenna resonates in a frequency band corresponding to the length of the first slot 215, so that the slot antenna is most activated when it is connected to the first point C1, which is an intermediate point of the first side member 210. [

In the slot antenna mode, the first side member 210 is resonated at a frequency corresponding to the length of the first slot 215 by the length of the first slot 215, The resonance frequency is larger than the resonance frequency due to the current flow in Fig. 8 (a). Resonance occurs at the frequency of f _low2 as shown in the graph of Fig.

Next, referring to FIG. 8 (c), the first conductive pattern 241 in the loop mode operates in the loop antenna mode and transmits a signal in the high frequency band. The signal of the high frequency band can resonate in a frequency band corresponding to twice the length of the first conductive pattern 241 because the wavelength is short.

As described above, the first antenna structure of the present embodiment operates as an inverse F antenna, a slot antenna, and a loop antenna, and can transmit and receive signals in various frequency bands.

FIG. 9 is a conceptual diagram of a mobile terminal 100 for explaining a first antenna structure according to another embodiment of the present invention, FIG. 10 is a graph for explaining the operation and performance of the first antenna structure of FIG. 9, 11 is a view for explaining the operation of the first antenna structure of FIG.

The first conductive pattern 241 of this embodiment is connected to the second point C2 of the first side member 210. [ 9, the first conductive pattern 241 is connected to the first side member 210 and the second side member 210 from the power feeding part 185 at a second point C2 (C2) ). Since the first conductive pattern 241 is located at the corner of the first side member 210, a large amount of electric field is gathered at corner portions of the terminal body, thereby maximizing the ground boosting effect. That is, the amount of radiation through the base plate 230 is increased.

Since the first conductive pattern 241 is connected adjacent to the grounding part connected to the first side member 210 and the base plate 230, the performance is activated as an inverted F antenna and the Q factor (quality factor) is excellent As shown in the graph of Fig. 10, resonance efficiency is high at f _low1 . The bandwidth B2 is smaller than the bandwidth B1 of the embodiment in which the first conductive pattern 241 is connected to the first point C1 described above.

Referring to FIG. 11 (a), the current flows when operating in the inverse F antenna mode. When power is applied through the first feeder 185 as in the above-described embodiment, a current flows along the first side frame and the first stub 246, and the sum of the lengths of the first side frame and the first stub 246 _Resonates at f _low1 having a wavelength corresponding to four times.

Referring to FIG. 11 (b), a current flows in the case of operating in the slot antenna mode, and a slot 215 between the first side frame and the base plate 230 as shown in the above- 210a may be open and the second end 210b may be a closed slot. The resonance frequency f _low2 having a wavelength corresponding to four times the length of the first slot 215 is determined. In this embodiment, the performance is better in the inverse F antenna mode, (f _low2 ) is lower than in the above-described embodiment (see Fig. 10).

The mobile terminal 100 of the present embodiment further includes a second stub 248 extending from the second point C2. The second stub 248 itself operates in the inverse F antenna mode and the wavelength corresponding to four times the length of the second stub 248 as shown in FIG. The resonator resonates at a frequency. The second stub 248 may be implemented in a similar manner to the first stub 246 described above and may be connected to the second point C2 by a connecting member such as a C-clip. Since the second stub 248 is shorter than the first side member 210, the second stub 248 resonates at a _high frequency (f _high ) (see FIG. 10).

FIG. 12 is a conceptual diagram of a mobile terminal 100 for explaining a first antenna structure according to another embodiment of the present invention, FIG. 13 is a graph for explaining the operation and performance of the first antenna structure of FIG. 12, FIGS. 14 and 15 are views for explaining the operation of the first antenna structure of FIG.

The first conductive pattern 241 of this embodiment is connected to the third point C3 of the first side member 210. [ The third point C3 is located at the first end 210a of the first side member 210 as shown in Figure 12 and the first conductive pattern 241 is located at the third feed point 185, Extends along side first member 210 towards point C3.

The first conductive pattern 241 connected to the third point C3 forms a loop with the first side member 210 so that the antenna of this embodiment is most activated in the loop mode as shown in Figure 14 (a) Rather, the inverse F antenna mode is suppressed. _Resonates at a frequency f _low1 having a wavelength twice the size of the loop formed by the first side member 210 operating in the loop mode and the first conductive pattern 241. [

Since the above embodiments operate as inverse F antennas in a low frequency band, the present embodiment operates as a loop antenna, so the bandwidth B3 is large and the Q factor is small.

14 (b) shows a current flow when operating in the slot mode, and a slot antenna is implemented in a similar manner to the above-described embodiment. However, the connection point of the first conductive pattern 241 is connected to the third point C3, which is the first end 210a of the first slot 215, so that the function as a slot antenna is lowered, The efficiency of the antenna at the resonant frequency f _low2 of the slot antenna is small.

In this embodiment, the loop antenna mode is enhanced compared to other embodiments, and resonance occurs in two frequency bands when operating as a loop antenna. Fig. 15A is a view for explaining a characteristic of resonating at a frequency (f _mid ) having a wavelength which is one magnitude of a loop, and shows a current flow similar to that in Fig. 14A. However, resonance occurs in the _mid- frequency band having a wavelength twice as long as the resonance frequency f _low1 of the low frequency because the resonance frequency is resonated at the frequency f _mid having a wavelength that is one times the size of the loop.

Referring to FIG. 15 (b), the current flows when resonating at a frequency f _high having a wavelength corresponding to twice the length of the first conductive pattern 241. The high frequency band signal is transmitted and received through the first conductive pattern 241.

Since the third point C3 to which the first conductive pattern 241 of this embodiment is connected is located at the farthest distance from the first corner 213 as compared with the above embodiments, The radiation performance through the base plate 230 is lowered.

As described above, in order to use the base plate 230 as a radiator, the first corner 213 of the first side member 210 must be filled with the first conductive pattern 241, (The second embodiment in Fig. 9) is located most adjacent to the second contact portion 213. However, in this case, since the bandwidth is small at the low frequency resonance frequency and the operation is suppressed in the slot mode, the usable frequency band is small and the convenience of resonance control is reduced.

The closer the first conductive pattern 241 is connected to the first end 210a (Embodiment 3 of FIG. 12), the lower the performance but the larger the bandwidth of the resonant frequency and the resonant frequency are varied. The embodiment of FIG. 4 shows the intermediate efficiency of the second embodiment and the third embodiment, and the easiness of the resonance control is also intermediate. Each of the embodiments has advantages and disadvantages and it is possible to provide an antenna having the best performance by merely changing the connection point of the first conductive pattern 241 with the first side member 210 for each mobile communication provider.

Hereinafter, operation and performance will be described in the case of transmitting and receiving signals in the mid-frequency band and the high-frequency band using the second antenna structure including the second side member 220 and the second conductive pattern 242. FIG. 16 is a graph for explaining the operation and performance of the second antenna structure according to the embodiment of the present invention. FIG. 17 is a view for explaining the operation in the second antenna structure according to the embodiment of the present invention. to be. The first antenna structure and the second antenna structure shown in FIGS. 4, 9, and 12 are disposed adjacent to the first side of the mobile terminal 100, and therefore, influence each other. Particularly, in this embodiment, since the slit 235 is located only at the lower end of the first side, interference can be severely caused at the slit 235.

In order to minimize the influence of the first antenna structure and the second antenna structure on each other, it is preferable to separate the first side member 210 and the second side member 220 as much as possible, but the size of the mobile terminal 100 is limited Since the first side member 210 and the second side member 220 are exposed to the outside, there is a problem that the quality of the slit 235 deteriorates in terms of design.

The present invention utilizes an indirect feed scheme that supplies power to the second side member 220 to minimize the influence between the first antenna structure and the second antenna structure in the mobile terminal 100 of a limited size.

One end of the second conductive pattern 242 is connected to the feeding part 187 and the other end is adjacent to the fourth point C4 of the second side member 220 without being directly in contact with the fourth point C4 . An insulating material may be interposed between the fourth point C4 and the second conductive pattern 242 to maintain the spacing between the second conductive pattern 242 and the second side member 220. [ The insulating material may be an insulating plate or an insulating film on which the second conductive pattern 242 is formed, or an elastic member such as an insulating gasket may be used. When the power is supplied to the second conductive pattern 242 from the power feeding part 187, the second side pattern 220 can be fed through the electric field formed by the second conductive pattern 242.

The second side member 220 can utilize both the slot antenna mode and the inverted F antenna mode by using the indirect feed method as opposed to the direct feeding method of the first conductive pattern 241. [ When the second conductive pattern 242 is directly fed at the fourth side point C4 with the second side member 220, the transmission coefficient S21 of the S parameter indicates -15 dB, so that the performance of the second antenna structure is poor. However, The transfer coefficient S21 of the S parameter is improved to -30 dB.

17A, the second conductive pattern 242 indirectly feeds the second side member 220 at the fourth point C4 and operates as an inverted F antenna. A second side member 220 is resonant at the first because of the side member 210, the length is shorter than the medium frequency having a wavelength shorter than the first resonance frequency of the side members 210 (f _low1) (f _mid1) (See FIG. 16). The resonant frequency f _mid1 may be a frequency having a wavelength corresponding to about four times the length of the second side member 220.

Referring to FIG. 17 (b), the operation of the second antenna structure in the slot antenna mode will be described. The resonance frequency f _mid2 is determined through the slot 225 formed by the second side member 220 and the base plate 230. The present embodiment adjusts the resonance frequency f _mid2 in the slot antenna mode And a third stub 249 extending along the slot 225 in order to allow the first stub 242 to move. The third stub 249 adjusts the resonance frequency f _mid2 when operating in the slot antenna mode. Referring to FIG. 17 (c), the second antenna structure may further include a separate auxiliary pattern 245 for resonance in the high frequency band. The auxiliary pattern 245 may be formed on the antenna carrier 105 or the printed circuit board 181. One end 245a of the auxiliary pattern 245 is grounded and the grounding point 245a of the auxiliary pattern 245 is grounded. And is disposed adjacent to the secondary feeder 183. The auxiliary pattern 245 of this embodiment also operates in the indirect feed method and resonates at a frequency f _high having a wavelength corresponding to twice the length of the auxiliary pattern 245 (see FIG. 16)

As described above, according to at least one embodiment of the present invention, it is possible to secure the radiation space of the antenna by improving the ground emission.

Also, according to at least one of the embodiments of the present invention, there is an advantage that the side portion of the mobile terminal 100 can be utilized as the radiator of the antenna.

It is possible to prevent deterioration of the antenna performance that occurs when the user holds the mobile terminal 100 by hand for using the mobile terminal 100, thereby ensuring consistent wireless communication performance.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet).
