Title: Yeon-Joo Lee and an Invention for Protecting Mobile RF Performance.
Introduction
Yeon-Joo Lee is an inventor associated with Incheon, South Korea, and Samsung Electronics Co., Ltd. Her patent work addresses a challenge in mobile communications: maintaining radio-frequency performance when an antenna’s impedance changes.
Latest Patents
The provided information identifies one patent for Lee: “Apparatus and Method for Preventing Degradation of RF Performance Due to Impedance Change of Antenna in Mobile Communication Terminal.” The invention describes a mobile terminal with multiple impedance-matching circuits. A controller measures the antenna’s reflection voltage, selects a matching circuit suited to that measurement, and connects the antenna through the selected circuit. This approach is designed to reduce reflection loss and help preserve the performance of the terminal’s RF module as antenna impedance varies. Lee’s listed patent count is 1 patent.
Career Highlights
Lee’s listed work connects her with Samsung Electronics Co., Ltd. The patent reflects an engineering focus on adapting antenna impedance matching to changing conditions in mobile communication devices.
