As such, the carrier is disposed adjacent to one end of the terminal body. More specifically, the battery 191 may be disposed on the opposite side, and a speaker or the like may be disposed between the carrier and the battery 191.

Antenna device 180 according to an embodiment of the present invention may be provided in plurality and may be formed to be close to the top or bottom of the terminal body, respectively. It may also be formed close to the side end of the terminal body.

When provided in plurality, the antenna device 180 is configured to transmit and receive radio signals corresponding to at least one of a personal communication system (PCS), an advanced wireless service (AWS), a digital communications network (DCN), and a long term evolution (LTE). The antenna may be one of a broadcast signal reception antenna, a Bluetooth antenna, a satellite signal reception antenna, and a data reception antenna of the wireless Internet operating in a band such as FM radio frequency band, Blue Tooth, or WIFI.

The antenna device 180 according to an embodiment of the present invention is a radio corresponding to at least one of a personal communication system (PCS), an advanced wireless service (AWS), a digital communications network (DCN), and a long term evolution (LTE). It can be used for an antenna that is configured to transmit and receive signals. As described above, the antenna device 180 according to an embodiment of the present invention is a smart antenna system for implementing MIMO (Multi Input Multi Out) technology, and may be regarded as a kind of 'hybrid antenna'.

As shown in FIG. 3, the antenna device 180 may be formed close to the top or bottom of the terminal body, and electrical elements such as a speaker or a motor may be disposed between the antenna and the battery 191. The antenna device 180 may be spaced apart from each of the electrical devices in consideration of radiation efficiency by the electrical device. However, since the antenna device 180 according to the present embodiment has more improved antenna characteristics, the display module 153 It may be arranged to cover at least a portion of).

5 is a perspective view of an antenna according to an embodiment of the present invention, FIG. 6 is a conceptual diagram of FIG. 4, and FIG. 7 is a graph showing radiation efficiency of the antenna shown in FIG. 4.

5 and 6, an antenna device 180 according to an embodiment of the present invention may include a first conductive member 181 and a second conductive member 182, a first connection member 183, and a power supply connection unit ( 187 and ground connection 188.

The first conductive member 181 and the second conductive member 182 are connected at one point of the circuit board 160 to extend along the first side 161 and bend at the corners to follow the second side 162. Is extended. The first side 161 and the second side 162 are two sides close to each other among the upper side, the lower side, the left side, and the right side of the circuit board 160. The second side 162 may be disposed to be close to the top or bottom of the terminal body, and the first connection member 183 connecting the first conductive member 181 and the second conductive member 182 to each other may be connected to the second side 162. When placed close to the side 162, the main radiation direction of the antenna can be directed to the top or bottom of the terminal body.

At this time, when the currents flowing along the first conductive member 181 and the second conductive member 182 are equal to each other in the first mode (common mode, common mode), the electric field distribution may be deformed, thereby causing hand The decrease in radiation efficiency due to the effect can be reduced.

The first conductive member 181 and the second conductive member 182 may be disposed in close proximity to each other within a predetermined interval such that coupling occurs with each other. The gap may be formed to have an interval within 1/10 of a wavelength corresponding to a specific frequency so that capacitive coupling may occur between the first conductive member 181 and the second conductive member 182. desirable.

5 and 6, in order to adjust the frequency resonance length corresponding to the path passing through at least one of the first conductive member 181 and the second conductive member 182, the first connection member ( A second connection member 184 may be further included to connect the first and second conductive members 181 and 182 to each other at a position spaced apart from 183. The resonance length corresponding to the low frequency or the high frequency may be adjusted according to the position of the second connection member 184.

The first conductive member 181 and the second conductive member 182 extend in parallel to each other, so that the capacitive coupling between the first conductive member 181 and the second conductive member 182 is reduced. As a result, even a shorter path can form a resonance length that can transmit and receive a specific frequency, thereby minimizing the antenna.

As the size of the terminal becomes smaller, the distance between the antenna 180 and the circuit board 160 is required to be further reduced. However, as the distance is reduced, resonance becomes difficult due to electrical interference between the circuit board 160 and each conductive member constituting the antenna. In addition, mismatch efficiency may increase.

By configuring the antenna 180 according to an embodiment of the present invention as described above, as shown in Figure 7, it is possible to maintain a constant radiation efficiency at a specific frequency. That is, according to an embodiment of the present invention, even if the distance between the antenna 180 and the circuit board 160 is within 1.5 mm (see FIG. 4), it is possible to maintain a constant performance of the antenna 180.

The first conductive member 181 and the second conductive member 182 each have a resonance length corresponding to λ / 4 of a specific frequency.

The first conductive member 181 and the circuit board 160 are connected to the power supply by the power supply connection part 187. The feed connector 187 feeds the first conductive member 181 with an electrical connection (or an electro-magnetic feeding method). The power supply connection unit 187 electrically connects a power supply device (not shown) and the first conductive member 181.

For this connection, the feed connection unit 187 may include a feed plate, a feed clip and a feed line. Here, the feeder plate, the feeder clip and the feeder line are electrically connected to each other to transmit current (or voltage) fed through the feeder to the conductor of the radiating unit. Here, the feed line may include a microstrip printed on a substrate.

The plurality of conductive members 182 may be at least partially formed of a conductor and operate as a radiator. The plurality of conductive members 182 may be manufactured in various forms according to resonance or frequency characteristics. The current is supplied to the conductor through the power supply connection 187, and the current supplied through the ground connection 188 is short-circuited.

The second conductive member 182 may be grounded by the circuit board 160 having the ground and the ground connection 188. The ground connection 188 is thus grounded to the second conductive member 182 and electrically shorted to achieve antenna resonance frequency and impedance matching. The spacing between the feed connection 187 and the ground connection 188 can be adjusted for impedance matching. For example, as the power supply connection unit 187 and the ground connection unit 188 are closer to each other, the bandwidth decreases, and as the distance increases, the impedance increases.

The ground connection 188 electrically connects an electrical ground and one end of the second conductive member 182 to ground the second conductive member 182. The electrical ground may be the ground on the circuit board 160.

Here, the ground connection 188 may include at least two paths having different lengths, and may include a switch corresponding to each path. In addition, through a switch to select each path, each path selectively connects electrical ground and radiators to different lengths. Here, the path is an electrical passage connecting the ground and the radiator, and may include a ground plate, a grounding clip, and a ground line. Further, the lengths of the paths can be formed differently by forming the ground wires to have different lengths.

In addition, unlike the above-described method, the second conductive member 182 may be electrically connected and the first conductive member 181 may be connected to the ground.

One of the conductive members 181 and 182 is formed of the first sub conductive member 185 or the second sub conductive member 186. The sub conductive members 185 and 186 may be formed in the first conductive member 181, or alternatively, may be formed in other conductive members.

5 and 6, the first subconductive member 185 and the second subconductive member 186 are disposed in the first conductive member 181. The first sub conductive member 185 is formed to expand the bandwidth in the high frequency band, and the second sub conductive member 186 is formed to expand the bandwidth in the low frequency band.

The sub conductive members 185 and 186 may be disposed between the conductive members 181 and 182, or alternatively, may be formed outside the conductive members 181 and 182. However, for capacitive coupling or inductive coupling, the conductive members 181 and 182 are spaced at a constant distance and extend in parallel.

As shown in FIGS. 5 and 6, the first sub conductive member 185 is connected to one end of the first conductive member 181 to which the power supply connection unit 187 is connected, so as to be connected to the first conductive member 181. Extends in parallel. Alternatively, one end of the second conductive member 182 may extend in parallel with the second conductive member 182.

The second subconductive member 186 is connected to the first conductive member 181 at a point away from one end of the first conductive member 181 by a resonance length corresponding to λ / 8 of a specific frequency. The second sub conductive member 186 may maintain the separation distance with the second conductive member 182 within 3 mm to 6 mm. As a result, inductive coupling may occur between the second subconductive member 186 and the second conductive member 182. When the separation distance between the second subconductive member 186 and the second conductive member 182 is wide, the radiation efficiency may increase, but the mismatching efficiency may decrease.

If at least a portion of the second sub conductive member 186 is formed to have a planar patch shape, the second sub conductive member 186 may operate in a resonance mode of a PIFA antenna in a low frequency band. This allows double resonance in the low frequency band and can significantly increase the bandwidth. The low frequency band may include a frequency band corresponding to long term evolution (LTE).

Also, unlike the foregoing, the second subconductive member 186 may be connected to the second conductive member 182 at a point away from one end of the second conductive member 182 by a resonance length corresponding to λ / 8 of a specific frequency. It may be.

The center frequencies shown in FIG. 7 range from a low frequency band to a long term evolution (LTE) band (700 to 787 MHz,), a global system for mobile communication (GSM) band (850 to 950 MHz), and a digital cellular system (DCS). And PCS (Personal Communication System) band (1700-1900 MHz) and WCDMA (Wideband CDMA) communication band (2.4GHz). As shown, according to an embodiment of the present invention it can be seen that even if the circuit board 160 and each of the conductive members 181, 182 of the antenna are arranged close to each other can exhibit sufficient antenna performance.

8 and 9 are conceptual views illustrating the modified embodiment of FIG. 4, in which the shape of the conductive members 181 and 182 is modified to have a sufficient resonance length of the antenna when the mobile terminal becomes smaller.

FIG. 8 is a tortuous shape such that the first conductive member 281 and the second conductive member 282 form a predetermined length corresponding to a specific frequency in a region close to the second side surface 162 of the circuit board 160. It is shown to include a meander structure formed of a conductor of.

As a result, the size of the antenna can be further reduced.

9 illustrates that the first conductive member 381 and the second conductive member 382 are bent in a region adjacent to the second side surface 162 of the circuit board 160 to extend the resonance length. In this case, since coupling occurs between each member and the bent members, it may have an operation characteristic different from that of the existing antenna.

In the case of configuring the antenna in this manner, the size of the antenna can be made smaller than that of the antenna shown in FIG.

The mobile terminal according to an embodiment of the present invention as described above is not limited to the configuration and method of the above-described embodiments, but the embodiments are a combination of all or some of the embodiments selectively so that various modifications can be made. It may be configured.
