The first and second antenna units 141 and 142 are formed to transmit and receive radio signals. The first and second antenna units 141 and 142 may be the same type of antennas or may be different types of antennas.

For example, as shown in the figure, the first antenna unit 141 may include a conductive radiator 141a and a carrier 141b.

The conductive radiator 141a may be formed of a thin metal plate of a conductive material, for example, gold, copper, or the like. The conductive radiator 141a is formed in a pattern capable of transmitting and receiving radio signals, and disposed adjacent to the rear case 122. [ Accordingly, the wireless signal is transmitted and received mainly through the rear case 122.

The carrier 141b is formed so that the conductive radiator 141a is seated on one surface. One end of the conductive radiator 141a passes through the through hole and is bent in the direction toward the circuit board portion 143. The conductive radiator 141a has a through hole, The bent portion is electrically connected to the circuit board portion 143, through which the conductive radiator 141a is fed to the circuit board portion 143. [

The circuit board portion 143 is electrically connected to the first and second antenna portions 141 and 142, respectively, to process a radio signal. The circuit board unit 143 may be configured as an example of a controller 170 (see FIG. 10) for operating various functions of the mobile terminal.

The second antenna unit 142 is a chip antenna. A chip antenna refers to an antenna integrated to form a single chip, and is miniaturized as a conductive layer and an antenna pattern are stacked. The conductive layer is electrically connected to the antenna pattern to ground the antenna pattern. The second antenna unit 142 may be surface mounted on the auxiliary circuit board unit 144 and may be disposed on the opposite side of the first antenna unit 141 with the circuit board unit 143 interposed therebetween .

Through the electrical connection, the circuit board part 143 can process a radio signal transmitted / received from the second antenna unit 142.

The first and second antenna units 141 and 142 may be connected to the circuit board unit 143 to transmit and receive radio signals of the first and second frequency bands, respectively. Either one of the first and second frequency bands may be a higher frequency band than the other.

For example, the first frequency band may be allocated to a GSM (Global System for Mobile communication) scheme, the second frequency band may be allocated to a Wideband Code Division Multiple Access (WCDMA) scheme, a Long Term Evolution Frequency band.

The second conductive portion 146 is configured to ground the second antenna portion 142. Referring to these drawings, a second conductive portion 146 is formed on a layer on which the first conductive portion 145 is formed in the circuit board portion 143.

The nonconductive region 147 is formed between the first and second conductive portions 145 and 146 to separate the first and second conductive portions 145 and 146 from each other. More specifically, for example, a conductive material is formed to cover one layer of the circuit board portion 143, and a nonconductive region 147 in which a part of the conductive material is peeled off is formed. The peeled portion forms the nonconductive region 147, and the first and second conductive portions 145 and 146 are physically disconnected from each other.

That is, the second conductive portion 146 may be formed at one corner of the circuit board portion 143. The second conductive portion 146 may be formed with a smaller area than the first conductive portion 145. Since the second antenna unit 142 is a chip antenna grounded by a separate conductive layer, the area of the second conductive unit 146 forming the ground of the second antenna unit 142 is smaller than that of the first conductive unit 145 Can be.

As described above, the first conductive portion 145 occupying most of the one layer of the circuit board by the non-conductive region 147 can be separated from the second antenna portion 142.

Generally, when a plurality of antennas are disposed adjacent to each other, mutual interference occurs. Mutual interference can be, for example, in the form of mutual coupling that can occur in the same frequency band, isolation required in other frequency bands, and so on. If mutual coupling occurs or isolation is not realized, implementation of multi-input multi-output (MIMO) in a mobile terminal becomes difficult.

The antenna apparatus 140 of the present invention can reduce the influence of mutual coupling of a plurality of antenna units. If there is no non-conductive region 147, the first and second conductive portions 145 and 146 will form a single ground, so that a mutual coupling to a plurality of antenna portions will occur.

The memory 164 may store a program for processing and controlling the control unit 170 and may have a function for temporarily storing input / output data (e.g., a phone book, a message, a still image, .

In the memory 164, a program for controlling the operation of the mobile terminal related to the present invention is stored

Such memory 164 includes the concept of a generally known hard disk, a card type memory (e.g., SD or XD memory), flash memory, RAM, ROM, and the like.

The broadcast receiving module 165 receives broadcast signals transmitted through satellite or terrestrial waves and converts the received broadcast signals into broadcast data formats that can be output to the sound output units 114 and 131 and the display unit 113 and outputs them to the controller 170. Further, the broadcast receiving module 165 receives additional data (e.g., EPG (Electric Program Guide), channel list, etc.) related to broadcasting. The broadcast data and the additional data converted by the broadcast receiving module 165 may be stored in the memory 164.

The power supply unit 127 receives external power and internal power under the control of the controller 170 and supplies power required for operation of the respective components.

The antenna device and the mobile terminal including the antenna device are not limited to the configuration and the method of the embodiments described above, but all or a part of the embodiments may be selectively combined so that various modifications may be made. .
