Abstract (en)

[origin: EP3852496A1] A microwave treatment apparatus includes: a treatment chamber configured to accommodate a heating target; a microwave supply configured to supply microwaves to the treatment chamber; and a resonator unit having a resonance frequency in a frequency band of microwaves. The resonator unit includes a plurality of patch resonators disposed such that at least three patch resonators are arranged along an orientation of a polarization plane generated on a metal wall constituting the treatment chamber. According to an aspect, a standing wave distribution in the treatment chamber, that is, a microwave energy distribution, can be controlled.
