Electromagnetic wave discharge emission device

Abstract

To provide an electromagnetic wave discharge emission device, a discharger in small size for causing a discharge only by an electromagnetic wave, that can significantly be reduced in length in a longitudinal direction, and configured to emit the electromagnetic wave into a target space based on an output of the supplied electromagnetic wave. The electromagnetic wave discharge emission device comprises an electromagnetic wave oscillator MW configured to oscillate an electromagnetic wave, a controller 2 configured to control the electromagnetic wave oscillator MW, a first substrate 10 provided with a plurality of discharge emission patterns 11 each having a power receiving end 11a on the main surface side, and a second substrate 20 provided with a feed pattern 22 having a power receiving port 21 configured to receive a power of the electromagnetic wave from the electromagnetic wave oscillator MW and a plurality of power feed ends 22a each connected through a via to one of the power receiving ends 11a, a distance on the feed pattern 22 from the power receiving port 21 to each power receiving end 11a of the corresponding discharge emission pattern 11 being equal to one another. Each of the discharge emission patterns 11 is formed in a spiral shape that has at a center thereof the corresponding power receiving end (s) 11a connected to the feed pattern 22 and has a length which corresponds to ¼ wavelength of the electromagnetic wavelength supplied to the feed pattern 22.
