Samsung patents phone antenna tuning that adjusts during calls
This patent describes a method for electronic devices to adjust how their antennas work while handling two different types of wireless connections at once. The device monitors the strength of the signal during a voice call and switches between two tuning modes to balance performance between the two connections.
In the filing’s own words
According to an embodiment, an electronic device may include memory storing instructions, a plurality of antennas including a first antenna configured to transmit and receive radio frequency (RF) signals corresponding to a first radio access technology (RAT) and a second RAT, and a second antenna configured to receive RF signals corresponding to the first RAT and the second RAT, an RF circuit coupled to the plurality of antennas, and at least one communication processor, comprising processing circuitry, operatively coupled to the memory and the RF circuit. The instructions, when executed by at least one communication processor, individually and/or collectively, may cause the electronic device to: establish a first transmission channel connection based on the first RAT and a second transmission channel connection based on the second RAT using one of the plurality of antennas, identify whether a voice call based on the first RAT is executed, and operate in a first antenna tuning mode, based on an electric field based on the first RAT being equal to or greater than a first value, and operate in a second antenna tuning mode, based on the electric field based on the first RAT being less than the first value, during execution of the voice call. Based on the first antenna tuning mode being switched to the second antenna tuning mode according to a change in the electric field, a parameter associated with antenna sensitivity of the second transmission channel connection based on the second RAT may decrease.
What exactly they claim (claim 1)
1. An electronic device comprising: memory storing instructions; a plurality of antennas including a first antenna configured to transmit and receive radio frequency (RF) signals corresponding to a first radio access technology (RAT) and a second RAT, and a second antenna configured to only receive RF signals corresponding to the first RAT and the second RAT; an RF circuit coupled to the plurality of antennas; and at least one communication processor, comprising processing circuitry, operatively coupled to the memory and the RF circuit, wherein the instructions, when executed by at least one communication processor, individually and/or collectively, cause the electronic device to: identify whether dual connectivity including the first RAT and the second RAT is activated; operate in a first antenna tuning mode for the first antenna that is used for transmission of signals corresponding to the first RAT and the second RAT, based on activation of the dual connectivity; when a voice call is executed, identify whether the voice call corresponds to the first RAT or the second RAT; and based on identifying that the voice call corresponds to the first RAT: maintain the first antenna tuning mode for the first antenna, based on an electric field based on the first RAT being equal to or greater than a first value, and change to a second antenna tuning mode, based on the electric field based on the first RAT being less than the first value, during execution of the voice call, and wherein a difference between antenna efficiencies, for transmitting signals of the first antenna, of the first RAT and the second RAT is smaller in the first antenna tuning mode than in the second antenna tuning mode.
