For example, the plurality of antennas may include one or more antennas (eg, a first top antenna 203 and a second top antenna 205) located in the top area of the electronic device 201. Additionally, for example, the plurality of antennas may include one or more antennas (e.g., the first lower antenna 207 and the second lower antenna 209) located in the lower area of the electronic device 201. there is.

Among the top antenna, the front camera 211, and the plurality of rear cameras 213, the distance between the camera and the top antenna may be shorter than the distance between the camera and the bottom antenna.

According to one embodiment, a top antenna (e.g., the first top antenna 203 or the second top antenna 205) and a bottom antenna (e.g., the first bottom antenna 207 or the second bottom antenna 209) can transmit signals at the same time. Signals transmitted by the top antennas 203 and 205 may cause interference to at least one of the front camera 211 or the plurality of rear cameras 213. The signal may be referred to as an interference signal. These interfering signals can degrade the performance of a running camera. For example, the interference signal may cause noise in an image acquired through the at least one camera.

According to one embodiment, the at least one processor (e.g., processor 120 in FIG. 1) transmits a signal transmitted by the upper antennas 203 and 205 to reduce performance degradation of electronic components due to the interference signal. The phase of and the phase of the signal transmitted by the lower antennas 207 and 209 can be adjusted. For example, the at least one processor 120 may delay the phase of the top antennas 203 and 205 to reduce camera performance degradation caused by the interference signal. For example, the at least one processor 120 may delay the phase of the signal from the lower antennas 207 and 209 to reduce performance degradation of the at least one camera due to the interference signal. For example, the at least one processor 120 may determine the phases of the signals of the upper antennas 203 and 205 and the lower antennas 207 to reduce performance degradation of the at least one camera due to the interference signal. 209) can delay all phases of the transmitted signal. As an example, the at least one processor 120 may delay the phase of the signal transmitted by the top antennas 203 and 205 by about 180 degrees. For example, the at least one processor 120 may delay the phase of the signal transmitted by the lower antennas 207 and 209 by about 120 degrees. When the phase of the signal transmitted by the upper antennas 203 and 205 is adjusted, the characteristics (e.g., strength, direction) of the interference signal affecting the camera's shooting may vary. If the phase of the signal transmitted by the lower antennas 207 and 209 is adjusted, the characteristics of the interference signal affecting the camera's shooting may vary. Changes in the characteristics of the interference signal can reduce camera performance degradation.

According to one embodiment, the at least one processor 120 may identify whether performance degradation of an electronic component has occurred or whether conditions related to performance degradation have been met. For example, the at least one processor 120 may obtain an error count value of the at least one camera. Based on obtaining an error count value greater than a specified value, the at least one processor 120 may identify that camera performance is degraded due to interference of wireless signals. The at least one processor 120 may identify that the operating frequencies of the upper antennas 203 and 205 are within the frequency range associated with the camera, based on the error count value of the camera. The at least one processor 120 may identify that the operating frequency of the lower antennas 207 and 209 is within the frequency range associated with the camera, based on the error count value of the camera. The frequency range associated with a camera refers to the range of frequencies that affect the operating performance of the camera.

For example, the at least one processor 120 may identify whether an electric field change amount greater than a threshold value is caused. The amount of electric field change refers to the amount of change in the electric field caused by the signals of the upper antennas 203 and 205 and the signals of the lower antennas 207 and 209. The at least one processor 120 may identify whether an electric field change amount greater than a threshold value is caused by the top antennas 203 and 205. The at least one processor 120 may identify whether an electric field change amount greater than a threshold value is caused by the lower antennas 207 and 209. For example, when the at least one processor 120 identifies an electric field change amount greater than a threshold value, the at least one processor 120 may identify that the operating frequency of the upper antennas 203 and 205 is within the frequency range associated with the camera. For example, when the at least one processor 120 identifies an electric field change amount greater than a threshold value, the at least one processor 120 may identify that the operating frequency of the lower antennas 207 and 209 is within the frequency range related to the camera.

For example, the at least one processor 120 may refer to a mapping table. The mapping table may represent a relationship between the type and location of the at least one camera, the operating frequency of the first antenna, and the operating frequency of the second antenna. The mapping table may include, for each camera, information about the frequency range associated with the camera. For example, the at least one processor 120 may identify a frequency range from a mapping table based on a location according to the type of the at least one camera in operation. The at least one processor 120 may identify whether the operating frequency of the upper antennas 203 and 205 is within the frequency range set in the mapping table. The at least one processor 120 may identify whether the operating frequency of the lower antennas 207 and 209 is within the frequency range set in the mapping table. For example, the mapping table may be structured as shown in the table below.

The at least one processor 120 may identify phase adjustment information when performance degradation of the electronic component occurs or conditions related to performance degradation are met. The phase adjustment information may include a first phase adjustment value of the transmission signal for the lower antennas 207 and 209. The phase adjustment information may include a second phase adjustment value of the transmission signal for the upper antennas 203 and 205. The phase adjustment information may include a combination of a phase adjustment value for the lower antenna and a phase adjustment value for the antenna. For example, the at least one processor 120 identifies phase adjustment information based on the operating frequency of the top antennas 203 and 205 and a location according to the type of the at least one camera in operation, from a mapping table. can do. The at least one processor 120 may identify phase adjustment information based on a location according to the type of the at least one camera in operation from a mapping table. The at least one processor 120 may identify phase adjustment information based on the operating frequencies of the top antennas 203 and 205 from the mapping table. The phase adjustment information may include a first phase adjustment value of the transmission signal for the lower antennas 207 and 209. The phase adjustment information may include a second phase adjustment value of the transmission signal for the upper antennas 203 and 205. The first phase adjustment value and the second phase adjustment value may be determined based on at least one of a location according to the type of the at least one camera, an operating frequency of an antenna, or a location of the antenna. The characteristics (eg, intensity, direction) of the interference signal may be changed by the first phase adjustment value and the second phase adjustment value. Due to the changed characteristics of the interference signal, performance for the at least one camera may be increased.
