Optimal Design Method of RF-DC Conversion Circuits for Various Input and Load Conditions Required for Rectenna Site Design

The RF-DC conversion circuit measurement system that can determine the optimum microwave circuit with the input power and load resistance fixed was constructed. By measuring the diode operating impedance and microwave circuit impedance with the constructed system, it was found that both impedances are not complex conjugate. From the result and constructed measurement system, we showed the RF-DC conversion circuit design method for various input power and load resistance conditions.
