Latest Patents
Yu Ji holds a patent for an optical control type phased array antenna apparatus. This invention involves an array antenna composed of multiple antenna elements. The apparatus utilizes an optical signal processor that optically processes input high-frequency signals. It outputs optically processed signals that include signal components with phases corresponding to the directions from which radio wave signals arrive, maintaining frequencies equal to those of the input high-frequency signals. Each frequency converter mixes a received signal with the optically processed signal corresponding to the antenna element, resulting in a frequency-converted signal. This signal has a frequency that is the difference between the received signal and the optically processed signal. A combiner then combines these frequency-converted signals to produce intermediate frequency signals that correspond to the radio wave signals.
