Circular polarization generating system for microwave oven |
摘要 |
A microwave oven includes a magnetron for generating electromagnetic wave energy, a waveguide for guiding and directing the electromagnetic wave energy into a cavity body defining a cooking chamber, and an antenna for radiating the electromagnetic wave energy generated by the magnetron into the waveguide. The waveguide includes a first opening for uniformly dispersing the electromagnetic wave energy into the cooking chamber, a second opening for uniformly dispersing the electromagnetic wave energy into the cooking chamber, and a short circuit for providing a short surface to the antenna. The first opening is formed on a portion of the waveguide which contacts the cavity body and extends along a longitudinal direction. The second opening is spaced away from and having a predetermined angle with respect to the first opening.
