Samsung patents phone antenna switch for better signal transmission

Patent drawing
Patent drawing from the official filing.

Samsung describes a design for a portable electronic device that uses multiple antennas and switches to manage radio frequency signals. The system allows the device to send specific test signals to a wireless network by routing signals through different antenna paths in a set sequence.

Why it mattersThis is a technical improvement to how phones handle wireless connections, likely aiming to optimize signal quality during network checks.

In the filing’s own words

An example portable electronic device can include: a first antenna, a second antenna, and a third antenna; a first RFFE, a second RFFE, and a third RFFE which are configured to pre-process an RF signal; a first conductive wiring; a first switch including a (1-1)th terminal connected to the first antenna, a (1-2)th terminal connected to one end of the first conductive wiring, and a (1-3)th terminal connected to the first RFFE; a second switch including a (2-1)th terminal connected to the second antenna, a (2-2)th terminal connected to the third antenna, a (2-3)th terminal connected to the second RFFE, a (2-4)th terminal connected to the third RFFE, and a (2-5)th terminal connected to the other end of the first conductive wiring; an RFIC configured to convert RF signals inputted from the first RFFE, the second RFFE, and the third RFFE into a baseband signal, and convert the baseband signal into an RF signal so as to output the RF signal to the first RFFE; and a communication processor configured to control the first switch so as to sequentially connect the (1-3)th terminal to the (1-1)th terminal and the (1-2)th terminal when the portable electronic device operates in a first transmission mode for transmitting a sounding reference signal (SRS) to the wireless communication network by using the first RFFE, and control the second switch so as to sequentially connect the (2-1)th terminal and the (2-2)th terminal to the (2-5)th terminal while the (1-2)th terminal is connected to the (1-3)th terminal.
