Samsung patents antenna design that moves signal splitter outside RF module

Samsung describes an electronic device where a signal splitter, or coupler, is placed outside the main radio frequency module. This setup allows the device to monitor its own transmission signals while reducing internal noise caused by switching components.

Why it mattersThis is a specific hardware adjustment that may help improve signal stability in future devices, though it is a minor technical detail for most users.

In the filing’s own words

Provided is an electronic device including a transceiver configured to output a first transmission signal, a first radio frequency (RF) module configured to amplify the first transmission signal obtained from the transceiver to generate an amplified first transmission signal, a first antenna configured to transmit the amplified first transmission signal, and a main coupler provided outside the first RF module along a transmission path between the first RF module and the first antenna, and configured to output a first coupling signal corresponding to the first transmission signal. The first RF module includes at least one power amplifier configured to amplify the first transmission signal, and a switch configured to connect one of a plurality of input ports, including at least one input port connected to the main coupler and configured to receive the first coupling signal output by the main coupler, with an output port connected to the transceiver.

What exactly they claim (claim 1)

1. An electronic device comprising: a transceiver configured to output a first transmission signal; a first radio frequency (RF) module configured to amplify the first transmission signal obtained from the transceiver to generate an amplified first transmission signal; a first antenna configured to transmit the amplified first transmission signal; and a coupler along a transmission path between the first RF module and the first antenna, and configured to output a first coupling signal corresponding to the first transmission signal, wherein the coupler is connected to a fixed ground, wherein the first RF module comprises at least one power amplifier configured to amplify the first transmission signal, and a switch configured to connect one of a plurality of input ports with an output port connected to the transceiver, wherein the plurality of input ports of the switch comprise at least one input port connected to the coupler and configured to receive the first coupling signal output by the coupler, and wherein the coupler is provided outside the first RF module to reduce noise due to coupler switching in the first RF module.
