METHOD FOR MULTIBAND COMMUNICATION USING SINGLE ANTENNA AND ELECTRONIC DEVICE THEREFOR

Document Type and Number:

WIPO Patent Application WO/2020/231217

Kind Code:

A1

Abstract:

Disclosed is an electronic device that performs communication in multiple bands by using a single antenna, and includes an antenna, a radio frequency front end module (RF FEM) connected to the antenna, a first signal processing module connected to the RF FEM and configured to process a signal of a first radio access technology (RAT), and a second signal processing module connected to the RF FEM and configured to process a signal of a second RAT, the signal of the second RAT being different than the signal of the first RAT, and the RF FEM including a frequency separating circuit configured to separate a signal received through the antenna into the signal of the first RAT and the signal of the second RAT, and a switch including a first input terminal coupled with the antenna, a first output terminal coupled with an input terminal of the frequency separating circuit, a second input terminal coupled with one of output terminals of the frequency separating circuit, and a second output terminal coupled with a path for the first signal processing module.
