4 is a conceptual diagram of an antenna device and a circuit board according to an embodiment of the present invention.

The antenna device 200 includes a radiator 210, a power supply connection portion 220, and a ground connection portion 230. The radiator 210 is composed of one or more conductive members. The path from the feed connection 220 to the conductive members to the ground connection 230 has a physical length corresponding to a particular frequency. This physical length may be a physical length corresponding to (n *?) / M (where n, m is an integer) of the wavelength corresponding to the frequency.

The radiator 210 is formed spaced apart from the circuit board 170. Regarding the radiation efficiency, it is preferable that the radiators 210 are arranged to be distant from each other from various electric elements mounted on the circuit board 170.

In one example, if the circuit board 170 extends into the first plane, the radiator 210 may be disposed in a second plane orthogonal to the first plane. As a result, the electrical elements on the circuit board 170 and the radiator 210 can be spaced apart from each other.

The power supply connection unit 220 may be connected to one end of the conductive members to supply the conductive members in an electrical connection (or EM (Electro-Magnetic) power supply). For this connection, the power supply connection unit 220 may include a power supply plate, a power supply clip, and a power supply line. Here, the feed plate, the feed clip, and the feeder line are electrically connected to each other to transmit the current (or voltage) fed through the feeder to the conductor of the radiator 210.

The conductive members are at least partially formed of a conductor and operate with the radiator 210. The conductive members may be manufactured in various forms depending on the resonance or frequency characteristics. A current is supplied to the conductor through the power supply connection part 220, and a current supplied through the ground connection part 230 is short-circuited.

Any one of the conductive members can be grounded by the circuit board 170 with the ground and the ground connection 230. The ground connection 230 thus grounded and electrically short-circuited with any one of the conductive members to achieve antenna resonant frequency and impedance matching. The gap between the power supply connection part 220 and the ground connection part 230 can be adjusted for impedance matching. For example, the bandwidth decreases as the feed connection 220 and the ground connection 230 are closer to each other, and the impedance tends to increase as the distance increases.

The ground connection 230 electrically connects one end of one of the conductive members to the electrical ground to ground the conductive member. Electrical ground can be ground on circuit board 170.

Here, the ground connection unit 230 includes paths having at least two different lengths, and may be formed with a switch corresponding to each path. Also, through a switch that selects each pass, each pass selectively connects the electrical ground and conductive members to different lengths. Here, the path is an electrical path connecting the ground and the radiator 210, and may include a ground plate, a ground clip, and a ground line. Further, the lengths of the paths can be formed differently by forming the ground wires to have different lengths.

The gap between the power supply connection part 220 and the ground connection part 230 can be adjusted for impedance matching. For example, the bandwidth decreases as the feed connection 220 and the ground connection 230 are closer to each other, and the impedance tends to increase as the distance increases.

A wireless communication module 172 may be formed on one surface of the circuit board 170. The wireless communication module 172 includes an RF (Radio Frequency) transceiver to perform wireless communication using the airwaves. In wireless communication, the module communicates with the base station.

In the wireless communication module 172, the wireless communication distance may be increased and the sensitivity may be improved by using an antenna device installed separately. To this end, an antenna connector may be provided on one side of the module to connect the antenna device to the module. At this time, the antenna connector may be fixedly mounted on a printed circuit board (PCB) of the module to form a signal exchange path between the antenna and the RF transceiver.

The antenna device and the wireless communication module 172 are connected to each other by an RF cable 173. The RF cable 173 may be disposed on the circuit board 170 and may extend parallel to the circuit board 170.

A connection part 240 is formed at one end of the radiator 210. The connection unit 240 may be connected to the ground connection unit 230 and the power supply connection unit 220, respectively. The connection portion 240 includes a first extension portion 241 formed to cover a portion of the circuit board 170 and a second extension portion 241 extending in a direction intersecting the first extension portion 241 and extending in parallel to the side surface of the terminal body. 2 extension portion 242. [0033] The ground connection part 230 is formed near the lower end of the second extension part 242 and the power supply connection part 220 is formed near the upper end of the second extension part 242. Accordingly, since the feed connection unit 220 is formed at a predetermined distance from the circuit board 170, the radiation efficiency of the antenna can be improved.

Further, since the power supply pattern is not formed on the circuit board 170, the circuit board 170 can be more efficiently designed and the degree of freedom in arranging the electric devices is improved.

The circuit board 170 may be formed of a plurality of layers, and at least one layer forms a ground layer.

To ground the antenna, the ground connection 230 should be connected to the ground layer. At this time, the first extension portion 241 and the ground layer can be connected to each other by the boss portion 243 formed to penetrate the first extension portion 241 and the ground layer.

5, the radiator 210 may be formed to include a plurality of conductive members 311, 312, and 313. The radiators 210 include a first conductive member 311 configured to transmit and receive a radio signal in a first frequency band, a second conductive member 312 configured to transmit and receive a radio signal in a second frequency band, And a third conductive member 313 coupled to the second conductive member 312 to extend the band.

The first conductive member 311 may be configured to transmit and receive wireless signals in a digital cellular system (CS) and a personal communication system (PCS) band (1700 to 1900 MHz) or a wideband CDMA (WCDMA) .

The second conductive member 312 may be configured to transmit and receive wireless signals in the GSM (Global System for Mobile communication) band (850-950 MHz).

The third conductive member 313 may be formed to extend the physical length of the second conductive member 312 to transmit and receive wireless signals in the long term evolution (LTE) band (700 to 787 MHz).

That is, the first to third conductive members 311, 312 and 313 are formed to have a physical length capable of transmitting and receiving a radio signal corresponding to each frequency band, together with the power supply connection part 220 or the ground connection part 230 .

In order to maintain sufficient antenna characteristics while transmitting / receiving radio signals in the LTE (Long Term Evolution) band, the antenna device 200 must form an electrical length of? / 4 of at least 700 MHz, The size should increase. However, since the size of the antenna is limited according to the downsizing tendency of the terminal, it is required to exhibit the improved performance in the low frequency band while having a smaller volume.

To this end, the second and third conductive members 312, 313 may extend parallel to one another for a certain period to cause coupling. The spacing between the second and third conductive members 312 and 313 parallel to each other is preferably set to be within 1/10 of the wavelength corresponding to LTE (Long Term Evolution).

As a result, the capacitive coupling between the second and third conductive members 312 and 313 increases, so that a resonance length capable of transmitting and receiving a specific frequency can be formed even with a shorter path, can do. That is, a frequency corresponding to the LTE band can be transmitted and received even with a shorter physical length.

As described above, the third conductive member 313 is formed to expand the second frequency band. The third conductive member 313 may be connected to the second conductive member 312. The third conductive member 313 may be connected to the second conductive member 312 via a switch or may be disposed proximate to the second conductive member 312 such that capacitive coupling is achieved. An example of a switch is a single pole double throw (SPDT) switch.

The serial bus control unit 174 may be connected to one end of the third conductive member 313. In this case, For this reason, the serial bus control unit 174 receives the drive control signal by I-2C (I-Square-C) communication from the control unit. By the drive control signal, the second and third conductive members 312 and 313 can operate in the frequency band corresponding to long term evolution (LTE).

As shown in FIG. 6, the first mode (Mode 1) operates in a predetermined low-frequency band and a high-frequency band, respectively.

Thereafter, when switching is performed to operate in the LTE band, or when a signal is received from the control unit, the antenna operates in the second mode (Mode 2). That is, the low frequency band is extended, and the second conductive member 312 and the third conductive member 313 can transmit and receive radio frequencies corresponding to the LTE band. As a result, the low frequency band can be expanded while maintaining the bandwidth of the high frequency band.

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
