Abstract
A magnetron is configured so that an antenna leadconnected to a desired position of an anode segmentpasses through a magnetic pole pieceand a metal cylinderso as not to make contact therewith and is connected to the output portion of the magnetron, and so that the electrical length Lof this antenna leadbetween the opening end of a third harmonic restraint chokeand the connection portion of the anode segmentis 1/2 of the wavelength (λ) of the third harmonic, thereby restraining the third harmonic and the side bands of the third harmonic.
