MUMBAI, India, June 19 -- Intellectual Property India has published a patent application (202617057674 A) filed by Samsung Electronics Co. , Ltd. on May 06, 2026, for Antenna Switching Circuit And Electronic Device Comprising Same.
Inventors include Kang, Hyunsang; , Hyoseok; and Moon, Yohan.
The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: In embodiments, provided is an electronic device. The electronic device may comprise: a processor; a radio frequency (RF) transceiver; a first filter for a first frequency band; a second filter for a second frequency band; a radio frequency front end (RFFE) circuit including an antenna switching circuit; a first antenna; a second antenna; and an impedance adjustment circuit electrically connected to a sounding reference signal (SRS) output port of the antenna switching circuit. The impedance adjustment circuit may provide a characteristic impedance of a specified magnitude at the SRS output port of the antenna switching circuit. The first antenna may be used to transmit or receive signals in the first frequency band via the antenna switching circuit in which the characteristic impedance of the specified magnitude is provided to the SRS output port. The second antenna may be used to transmit SRSs in the second frequency band via the antenna switching circuit and the impedance adjustment circuit coupled to the SRS output port of the antenna switching circuit.
