Latest Patents

Yi-Yan Lee's latest patents include the "Frequency Modulation Continuous Wave Radar Level Meter" and the "Signal-Tracking and Phase-Locking Method for the Same." The FMCW radar level meter features an RF signal processing module, an intermediate frequency (IF) signal processing module, and a computation and display module. The RF signal processing module generates a first RF signal, which is radiated by an antenna to a measured object. The antenna then receives a second RF signal reflected by the measured object. The IF signal processing module processes the second RF signal and compares it with the first RF signal. The computation and display module calculates and displays the distance between the FMCW radar level meter and the measured object. This innovative design addresses issues of noise and temperature coefficient shift.

Another notable invention is the "Horn Antenna Device and Step-Shaped Signal Feed-In Apparatus Thereof." This invention relates to a horn antenna device that includes a step-shaped signal feed-in apparatus and a conical horn antenna. The step-shaped signal feed-in apparatus has a stepped body with multiple stairs and a connecting pin. This design allows for the easy determination of resonating modes, improving directivity and signal-to-noise ratio. Additionally, the connecting pin enhances the signal stability of the horn antenna device.
