I am implementing rf energy harvesting circuit. The rectenna is working at 915MHz and the impedance is 50Ω. I think L-matching may be the easiest. However, I don't have the vector network analyzer. Is there any way to calculate the parameters without the analyzer? Thanks. Here is the structure.enter image description here

  • \$\begingroup\$ What is the load? draw out your entire schematic. \$\endgroup\$ Mar 25 '19 at 17:04
  • \$\begingroup\$ I had uploaded a simplified structure diagram. I don't know the value of the load. I thought that we just consider the load of the rectifying circuit? Or should including the sensor load? \$\endgroup\$

  • \$\begingroup\$ your capacitor should be in parallel, not in series as you have a DC Block here. \$\endgroup\$

  • \$\begingroup\$ @SirSy, this is an abstract block diagram, not a circuit diagram. \$\endgroup\$
