Latest Patents

One of his latest innovations is the "Low Profile Mobile Tri-Band Antenna System." This system features a tri-band feeding unit that effectively divides satellite broadcasting signals by azimuth and elevation angles. It transmits and receives satellite communication signals while distinguishing between them. Additionally, the system includes a beam shaping unit that separates satellite broadcasting signals into first and second channel signals, allowing for combined power through channel switching. The antenna controlling unit drives the antenna system to direct towards the satellite based on the power combined second channel signal. Furthermore, the system incorporates a first triplexer unit for outputting the first channel signal and a second triplexer unit that converts the first channel signal to a downlink frequency for indoor apparatus use.

Another notable patent is the "Antenna System for Tracking Satellite." This system consists of a fixed body and a rotating body, featuring a transmitting/receiving unit with dedicated channels for signal power. The driving unit enables mechanical motion for satellite tracking, while the control unit monitors and controls the operation of the driving unit. This design minimizes the components mounted on the movable body and simplifies the system configuration, ultimately reducing production costs. The antenna system also includes a tracking signal processing function in both digital and analog modes, enhancing the accuracy of satellite tracking.
