Antenna and electronic device including the same

An electronic device, comprising:

• a first antenna element;
• a first switch configured to enable the first antenna element to receive signals of a first frequency band and a second frequency band or to receive signals of the first frequency band and a third frequency band;
• a second antenna element configured to receive a signal of the third frequency band;
• a first radio frequency (RF) block configured to process a signal of the first frequency band;
• a second RF block configured to process a signal of the second frequency band;
• a third RF block configured to process the signal of the third frequency band;
• a second switch configured to connect the first antenna element with the second RF block or the third RF block according to a connection of the first switch and connect the second antenna element with third RF block according to whether a network supports carrier aggregation (CA);
• a transceiver configured to be connected with the first RF block, the second RF block, and the third RF block;
• and
• a processor configured to be electrically connected with the transceiver,
• wherein, if the network supports CA, the processor controls the first switch such that the first antenna element receives the signals of the first frequency band and the second frequency band, controls the second switch to connect the first antenna element with the second RF block and connect the second antenna element with the third RF block, and enable the transceiver to perform CA using the signal of the second frequency band and the signal of the third frequency band.
