あつた。Conventionally, in high-frequency heating devices that aim for uniform heating using a rotating antenna, a roughly L-shaped rotating antenna is often used as shown in Figure 1, but the disadvantage of this rotating antenna is that most of the radio waves are emitted. It is a vertical electric field coupling type that is made from the vertical part, and there is very little radio wave radiation from the horizontal part, so the rotation effect is not very good.
