Electronic device including plurality of antennas and method of operating same

An electronic device comprising:

• a housing;
• a first antenna circuitry that is disposed in a first end portion in the housing, and comprises a first antenna and a first amplifier circuitry to output a signal corresponding to the first antenna;
• a second antenna circuitry that is disposed in a second end portion in the housing, and comprises a second antenna and a second amplifier circuitry to output a signal corresponding to the second antenna;
• a transceiver including a first port connected to the first antenna through the first amplifier circuitry, and a second port connected to the second antenna through the second amplifier circuitry, wherein a first plurality of amplifiers in the first amplifier circuitry is coupled to the first port and a second plurality of amplifiers in the second amplifier circuitry is coupled to the second port;
• and
• a processor configured to output a first signal corresponding to first data to the first port or the second port of the transceiver based on a frequency band of the first signal,
• wherein, when antenna switching is required while outputting the first signal through the first antenna and the frequency band of the first signal is a low-frequency band which is lower than a preset frequency value, the processor is configured to control to output the first signal through the second antenna, via the first port and the first amplifier circuitry, and
• wherein, when the antenna switching is required while outputting the first signal through the first antenna and the frequency band of the first signal is equal to or higher than the preset frequency value, the processor is configured to control to output the first signal through the second antenna, via the second port and the second amplifier circuitry.
