We report on the matching circuit designed in the matching circuit contest (85 kHz category) held on March 17, 2023. This contest was a competition to magnify the transmission coefficient S21 of a 2-port network of circuits connected to a fabricated matching circuit and a pre-distributed Zkown circuit. We find that the Zkown circuit is gyrator characteristic. By designing a matching circuit with a gyration resistance equal to the Zknown circuit, we exploit the through characteristic of the entire circuit and match it to 50 Ω. Several circuits exist that satisfy the gyrator characteristic. Among them, we dare to introduce a wireless element, named after the organizer, and fabricate a "magnetic field wireless matching circuit using Qi coils" to try to achieve a high transmission coefficient of S21. |
