Abstract:
1. A microwave generator including a central electrode ( 14 ) having a radiating element ( 22 ) at a front end, and an external electrode ( 18 ) which coaxially surrounds the central electrode ( 14 ) along an axially extending resonator portion ( 16 ), the two electrodes ( 14 and 18 ) possessing a rotationally symmetrical configuration and defining a spark gap ( 62 ) which sparks across upon the application of a high voltage and radiates microwaves through the radiating element ( 22 ) of the central electrode ( 14 ), the spark gap ( 62 ) being in the form of an annular spark gap which is determined by a connection element ( 26 ) which projects at a rear end axially centrally away from the central electrode ( 14 ) and an annular edge ( 44 ) of the external electrode ( 18 ), said edge being located coaxially with respect to the connection element ( 26 ).
