Embodiments disclosed in the present disclosure relate to a technology for transmitting/receiving signals in the same frequency band at the same time by using a plurality of antennas.
With developments of information communication technologies, network devices such as a base station and the like are installed throughout the country. The electronic device transmits/receives data to/from another electronic device over a network, thus allowing a user to utilize the network freely anywhere in the country.
The electronic device may use the network through at least one antenna included in the electronic device. The electronic device may include a plurality of antennas. The electronic device may transmit/receive a signal by using a main antenna of a plurality of antennas, and may receive a signal by using a diversity antenna of the plurality of antennas.
In an electronic device including a main part including one or more antennas and a diversity part including one or more antennas, two signals in the same frequency band may be simultaneously received through the main part and the diversity part, respectively. However, since the connection between an antenna and an RF circuit is not free, two or more antennas included in the main part and two or more antennas included in the diversity part may not be connected with the RF circuit which may transmit or receive signals in the same frequency band at the same time. Accordingly, the electronic device may be difficult to receive signals in the same frequency band at the same time through the two or more antennas of the main part or the two or more antennas of the diversity part.
Accordingly, various embodiments disclosed in the present disclosure may provide an electronic device including a circuit which may transmit or receive signals in the same frequency band at the same time by using a plurality of antennas included in the electronic device and a method thereof.

According to various embodiments disclosed in the present disclosure, an electronic device may include a plurality of circuits which are simultaneously connected with respective antennas and may transmit or receive signals in the same band, thus simultaneously transmitting or receiving signals in the same bands through all the antennas included in the electronic device.
For another example, a path through which each of the plurality of antennas is connected with a communication circuit may be variously changed by using a signal distributer or a switching circuit which connects the plurality of antennas and the communication circuit.

The electronic device according to an embodiment may receive a high band signal or a middle band signal at the same time through two antennas.
For example, the electronic device may include a plurality of antennas (the first antenna 110 and the second antenna 120). A signal received by the second antenna 120 may be transmitted to the LB transmitter/receiver circuit 150 or the H/MB receiver circuit 160 through the signal distributer 130 depending on a band of the signal.
According to an embodiment, the first antenna 110 may receive a signal from the outside or may radiate a signal transmitted within the electronic device. The first antenna 110 may receive or radiate, for example, the high band signal or the middle band signal. For example, the middle band may be a band ranging from approximately 1.7 GHz to approximately 2.1 GHz, and the high band may be a band ranging from approximately 2.3 GHz to approximately 2.7 GHz. The first antenna 110 may be electrically connected with the H/MB transmitter/receiver circuit 140. The first antenna 110 may be electrically connected with the H/MB transmitter/receiver circuit 140 through a first electrical path. The first electrical path may be configured to transmit the high band signal and the middle band signal. The first antenna 110 may transmit a signal received from the outside to the H/MB transmitter/receiver circuit 140. For another example, the first antenna 110 may radiate a signal transmitted from the H/MB transmitter/receiver circuit 140 to the outside.
According to an embodiment, the second antenna 120 may receive a signal from the outside or may radiate a signal transmitted within the electronic device. The second antenna 120 may receive or radiate, for example, the high band signal, the middle band signal, or a low band signal. For example, the low band may be a band ranging from approximately 600 MHz to approximately 900 MHz. The second antenna 120 may be electrically connected with the LB transmitter/receiver circuit 150 or the H/MB receiver circuit 160 through the signal distributer 130. For example, the second antenna 120 may be electrically connected with the LB transmitter/receiver circuit 150 or the H/MB receiver circuit 160 through a second electrical path. The second electrical path may be configured to transmit the high band signal, the middle band signal, and the low band signal. The second electrical path may simultaneously or selectively transmit the high band signal, the middle band signal, and the low band signal. The second electrical path may be changed by the signal distributer 130. For example, depending on an operation of the signal distributer 130, the second antenna 120 may be electrically connected with the LB transmitter/receiver circuit 150 through the second electrical path or may be connected with the H/MB receiver circuit 160 through the second electrical path. The LB transmitter/receiver circuit 150 or the H/MB receiver circuit 160 may be electrically connected with the second antenna 120 through the second electrical path. For example, the second antenna 120 may transmit the low band signal received from the outside to the LB transmitter/receiver circuit 150, and may radiate a signal transmitted from the LB transmitter/receiver circuit 150 to the outside. For another example, the second antenna 120 may transmit the high band signal or the middle band signal received from the outside to the H/MB receiver circuit 160. The second antenna 120 may be positioned at a location adjacent to the first antenna 110.

According to an embodiment, the electronic device may include two circuits (the H/MB transmitter/receiver circuit 140 and the H/MB receiver circuit 160) which are simultaneously connected with two respective antennas (e.g., the first antenna 110 and the second antenna 120) and may receive the high band signal or the middle band signal.
According to an embodiment, the signal distributer 130 may selectively or simultaneously connect the second antenna 120 with the LB transmitter/receiver circuit 150 or the H/MB receiver circuit 160. For example, the signal distributer 130 may transmit the low band signal of the signal transmitted from the second antenna 120 to the LB transmitter/receiver circuit 150 and may transmit the middle band signal and the high band signal thereof to the H/MB receiver circuit 160. The signal distributer 130 may include, for example, a switch, a diplexer, a duplexer, or the like. The switch may selectively connect the second antenna 120 with the LB transmitter/receiver circuit 150 or the H/MB receiver circuit 160. The diplexer or the duplexer may simultaneously connect the second antenna 120 with the LB transmitter/receiver circuit 150 or the H/MB receiver circuit 160. For example, in the case where the signal distributer 130 includes the diplexer, the signal distributer 130 may separate the low band signal and the high band/middle band signal. The signal distributer 130 may separate a signal and may transmit the separated signal to an appropriate circuit of the LB transmitter/receiver circuit 150 or the H/MB receiver circuit 160.
According to an embodiment, the H/MB transmitter/receiver circuit 140, the LB transmitter/receiver circuit 150, and the H/MB receiver circuit 160 may be implemented in one communication circuit included in the electronic device. For example, the communication circuit may receive at least a part of the high band signal and/or the middle band signal at the same time through a plurality of antennas included in the electronic device. For example, in the case where the high band signal and/or the middle band signal is received by the second antenna 120, the signal distributer 130 may allow the signal received by the second antenna 120 to be transmitted to the H/MB receiver circuit 160. For example, in the case where the H/MB transmitter/receiver circuit 140 is electrically connected with the first antenna 110 and the H/MB receiver circuit 160 is electrically connected with the second antenna 120 adjacent to the first antenna 110, the communication circuit may be configured to simultaneously receive at least a part of the high band signal and/or the middle band signal received by the first antenna 110 and the second antenna 120 by using the H/MB transmitter/receiver circuit 140 and the H/MB receiver circuit 160.

According to various embodiments, an electronic device may include a grip sensor which detects a contact of an object, and an application processor which is electrically connected with the grip sensor and a communication processor. The application processor may obtain information about a contact with the electronic device through the grip sensor. For example, in the case where a skin of the user is in contact with a metal housing being a radiator of a plurality of antennas, the application processor may obtain information about a point, with which the user's skin is in contact, through the grip sensor. The application processor may transmit the information about the contact to the communication processor. The communication processor may obtain the information about the contact from the application processor, and may block a connection of the communication circuit with a part of the plurality of antennas based on the information about the contact. For example, in the case where the point with which the user's skin is in contact corresponds to a radiator of a first antenna, the communication processor may stop communication using the first antenna. For another example, the communication processor may identify an antenna, the communication efficiency of which is reduced at a time when the contact is recognized and may stop communication using the identified antenna.

In operation 2530, the electronic device (e.g., a control circuit included in the electronic device 2601 or the electronic device 2701) may perform an operation of determining whether a contact is made. For example, the electronic device may determine whether an object is in contact with one or more antennas of the plurality of antennas, based on the information about the contact. For example, the electronic device may determine whether an object is in contact with the first antenna 2501 and/or the second antenna 2502. For example, the electronic device may determine whether an object is in contact with an antenna positioned at a touched point, based on the information about the touched point. For another example, the electronic device may determine that an object is in contact with an antenna, the communication efficiency of which is reduced at a time when the contact is recognized.
In the case where the determination result of operation 2530 indicates that an object is in contact with one or more antennas of the plurality of antennas, in operation 2540, the electronic device (e.g., a control circuit included in the electronic device 2601 or the electronic device 2701) may perform an operation of stopping the use of an antenna. For example, the electronic device may stop the use of the antenna with which an object is in contact. For example, in the case where the user's skin is in contact with the second antenna 2502 of the first antenna 2501 and the second antenna 2502, the electronic device may stop the use of the second antenna 2502 and may perform communication by using the first antenna 2501.
In the case where the determination result of operation 2530 indicates that an object is not in contact with an antenna, the electronic device may maintain the use of the plurality of antennas.
As described above, as the use of an antenna, the performance of which is reduced by a contact of an object, is stopped, the communication efficiency may not be reduced, and simultaneously, a power needed for communication may be reduced.
