1. An electronic device comprising:

  • a first antenna radiator configured to transmit and/or receive a signal of a first frequency band and a signal of a second frequency band;

    a second antenna radiator configured to transmit and/or receive the signal of the second frequency band, wherein at least a part of the second antenna radiator is arranged to be coupled with the first antenna radiator and includes a pattern having an electrical length corresponding to the first frequency band;

    a matching circuit electrically connected to the second antenna radiator, wherein the matching circuit is mismatched with the second antenna radiator in the first frequency band and is matched with the second antenna radiator in the second frequency band;

    a radio frequency (RF) circuit electrically connected to the first antenna radiator and the second antenna radiator; and

    a processor configured to control the RF circuit such that the signal of the second frequency band is transmitted or received through the first antenna radiator and the second antenna radiator in a multi-input multi-output (MIMO) mode or such that the signal of the first frequency band is transmitted and/or received through the first antenna radiator in a single input single output (SISO) mode.
