2450 MHz microwave trunk insecticidal radiator

The utility model provides a 2450 MHz microwave trunk insecticidal radiator, belonging to a bio-electronics microwave technical field. The radiator is mainly composed of a microwave source of 2450 MHz, 1KW, a waveguide square-circle converter and a microwave radiator; an output waveguide of the microwave source of 2450 MHz, 1KW is a rectangle; one end waveguide of the waveguide square-circle converter is a rectangular waveguide and the other end waveguide of the waveguide square-circle converter is a circular waveguide; a transition device made of brass is plated with red copper and silver on an inner surface; the microwave radiator is a circular brass waveguide and is filled with aluminum oxide ceramics with a relative dielectric constant of 2.5; and two ends of the circular brass waveguide are opened. The utility model is advantageous in that electromagnetic field distribution in the waveguide is fully considered, and impedances between the radiator and the microwave source are matched, thereby solving the
