Electronic apparatus and control method therefor

An electronic device, comprising:

• a first antenna of a first band, a second antenna of a second band partially overlapping the first band, a third antenna of the first band, and a fourth antenna of the second band;
• an ambient conductive member connected to a surrounding of a housing;
• a transmission/reception path corresponding to each of a plurality of bands;
• a reception path corresponding to each of the plurality of bands;
• and
• a path forming unit configured to form a path to connect any one of the first antenna and the third antenna to the transmission/reception path, the other of the first antenna and the third antenna to the reception path, any one of the second antenna and the fourth antenna to the transmission/reception path, and the other of the second antenna and the fourth antenna to the reception path, wherein at least one of the first antenna, the second antenna, the third antenna, or the fourth antenna includes at least part of the ambient conductive member.

An electronic device, comprising:

• an antenna module including first to eighth antennas;
• an ambient conductive member connected to a surrounding of a housing;
• a transmission/reception path including a first front end corresponding to a first band and a second front end corresponding to a second band;
• a reception path including a third front end corresponding to the first band and a fourth front end corresponding to the fourth band;
• and
• a main switch configured to connect one selected from among the first front end, the second front end, the third front end, and the fourth front end to each of a first sub switch, a second sub switch, a third sub switch, and a fourth sub switch,
• wherein at least one of the first to eight antennas includes at least part of an ambient conductive member, and wherein the first sub switch, the second sub switch, the third sub switch, and the fourth sub switch are connected to each of two antennas of the same band in the antenna module, allowing one of the two antennas each connected with the first sub switch, the second sub switch, the third sub switch, and the fourth sub switch to selectively connect to the main switch.

A method for controlling an electronic device including an ambient conductive member connected to a surrounding of a housing and a plurality of antennas, at least one of the plurality of antennas including at least part of the ambient conductive member, the method comprising:

• receiving a signal received through one or more of the plurality of antennas;
• performing a diversity operation upon receiving the signal through two or more of the plurality of antennas;
• measuring an electric field strength of the received signal;
• comparing the electric field strength with a threshold;
• and
• adding a reception antenna or maintaining the number of reception antennas according to the comparison, wherein the signal received through the one or more of the plurality of antennas is a signal of a frequency band jointly supported by the plurality of antennas.

A method for controlling an electronic device, the method comprising:

• identifying a transmit power of the electronic device;
• if the transmit power reaches a designated reference value or a command to increase the transmit power is identified while the transmit power reaches the designated reference value, comparing performances of the plurality of antennas using a previously measured offset and a received electric field of each of the plurality of antennas;
• and
• determining one antenna to perform transmission of a signal according to a result of the comparison.
