Analysis of the Output Antenna Coupling Region of a 2 450 MHz High-power Continuous-wave Magnetron
The influence of the position change of output antenna coupling region on the output performance of a 2 450 MHz high-power continuous-wave magnetron is analyzed.Firstly,the influence of the position change of coupling region on the parameters of the magnetron is theoretically analyzed by using equivalent circuit meth-od,and it is found that the change has an impact on the appearance quality factor Qe of the magnetron.Second-ly,PIC particle simulation analysis is conducted on the radial position and extraction position of the output anten-na by using electromagnetic simulation software,and it is found that the position change of coupling region has corresponding effects on the output power,operating frequency,and output efficiency of the magnetron.The re-search provides some references for solving the problems encountered in actual fabrication process.
