US 2016/0365909 A1 · ELECTRONIC DEVICE AND ANTENNA CONTROL METHOD THEREOF

Abstract

An electronic device is provided. The electronic device includes a first antenna, a second antenna, a transmission/reception path unit, a first reception path unit, a second reception path unit including a low noise amplifier (LNA), a signal path selection unit configured to connect each of the first antenna and the second antenna to the transmission/reception path unit, the first reception path unit, or the second reception path unit, and a radio frequency integrated circuit (RFIC) module or a processor including the RFIC module configured to control the signal path selection unit to have a first state in which the first antenna is connected to the transmission/reception path unit and the second antenna is connected to the second reception path unit or control the signal path selection unit to have a second state in which the first antenna is connected to the first reception path unit and the second antenna is connected to the transmission/reception path unit.

Dependent claims

An electronic device comprising:

a first antenna;
a second antenna;
a transmission/reception path unit;
a first reception path unit;
a second reception path unit including a low noise amplifier (LNA);
a signal path selection unit configured to connect each of the first antenna and the second antenna to the transmission/reception path unit, the first reception path unit, or the second reception path unit;
and
a radio frequency integrated circuit (RFIC) module or a processor including the RFIC module configured to:
control the signal path selection unit to have a first state in which the first antenna is connected to the transmission/reception path unit and the second antenna is connected to the second reception path unit, or

7 more elements

A method for controlling antennas of an electronic device, the method comprising:

if a first antenna operates as a main antenna and a second antenna operates as a sub antenna, determining performance of the first antenna corresponding to the main antenna;
determining whether the performance of the first antenna is suitable for the main antenna;
and
maintaining or switching the main antenna and the sub antenna based on a result of the determination,
wherein maintaining or switching the main antenna and the sub antenna comprises connecting each of the first antenna and the second antenna to a transmission/reception path unit, a first reception path unit, or a second reception path unit including a low noise amplifier (LNA).
