Abstract

An electronic device includes antennas, first radio frequency front ends (RFFEs) configured to pre-process a an RF signal having a frequency belonging to a first frequency band, second RFFEs connected to the antennas, respectively, wherein at least one of the second RFFEs is configured to pre-process an RF signal having a frequency belonging to a second frequency band different from the first frequency band, switches selectively connecting the first RFFEs to the respective antennas, a communication processor operatively coupled to the first RFFEs, the second RFFEs and the switches, and a memory storing instructions that, when executed, cause the processor to select a first antenna to support radio communication using the first frequency band among the antennas and control the switches to connect one of the first RFFEs to the first antenna and to open a connection between a remainder of the first RFFEs and a remainder of the antennas.

Dependent claims

An electronic device comprising:

a first antenna;
a second antenna spaced apart from the first antenna;
a first radio frequency front end (RFFE) electrically connected to the first antenna and configured to pre-process an RF signal having a frequency belonging to a first frequency band;
a second RFFE connected to the second antenna and configured to pre-process an RF signal having a frequency belonging to a second frequency band different from the first frequency band;
a third RFFE and a fourth RFFE configured to pre-process an RF signal having a frequency belonging to a third frequency band different from the first frequency band and the second frequency band;
a first switch positioned in a first conductive path electrically connecting the first antenna and the third RFFE;
a second switch positioned in a second conductive path electrically connecting the second antenna and the fourth RFFE;
and
a communication processor electrically connected to the first switch and the second switch and configured to control the first switch and the second switch and to transmit and/or receive a signal having a frequency belonging to at least one of the first frequency band, the second frequency band or the third frequency band.
