Impedance matching method of microwave oven and magnetron

摘要

The present invention relates to an impedance matching method of a microwave oven and a mark netron, and in a state in which the total length of the cap antenna 42 and the ceramic antenna 44 is constant, the length of the cap antenna 42 is adjusted or the cap antenna 42 is adjusted. And by changing the distance between the back wall 32 of the waveguide 30 and the capacitance in the waveguide 30, the impedance in the waveguide 30 is adjusted to match the impedance of the microwave to the magnetron impedance. The impedance within 30 can be easily adjusted, so that the impedance of the microwave oven can be easily matched to the impedance of the magnetron.
