Title: Innovations of Li Heng Zhou
Introduction
Li Heng Zhou is a notable inventor based in Nantong, China. He has made significant contributions to the field of microwave technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest inventions is the "Wideband Frequency Tunable Ring Resonator." This invention provides a wideband frequency tunable ring resonator that includes a closed λ/2 transmission line and two variable capacitors with tunable capacitance. The λ/2 transmission line is axisymmetric around a central line, with the first ends of the two variable capacitors connected to two intersection points of the λ/2 transmission line and the central line, while the second ends are grounded. This design allows for the fundamental resonant frequency (f) to be shifted up and down by controlling the respective values of the two loading capacitors, resulting in a bi-directional tuning of f. Consequently, the tuning range of this invention can be approximately doubled compared to conventional tunable ring resonators.
Another significant patent is the "Microwave Frequency Tunable Filtering Balun." This device comprises a first microwave split ring transmission line resonator and a second microwave split ring transmission line resonator arranged in a bilaterally symmetrical manner, along with a fourth and fifth variable capacitor of the same parameters. This invention combines the functions of a balun and a tunable bandpass filter (BPF) into one compact circuit. The balun characteristic and frequency-tuning mechanism are thoroughly investigated, and the design equations are derived.
