In a microwave oven, the frequency of the microwaves is fixed, typically at 2.45GHz. When the width of the waveguide is greater than half the wavelength of the microwaves, the microwave energy is effectively propagated in the waveguide.

In this embodiment, the height of the front section 120 is 3.8cm. The division of the waveguide cover 100 into three sections may make the structure simpler and easier to manufacture.
Referring to fig. 7 and 8, the present utility model further provides a waveguide assembly including a magnetron 400 and the waveguide for a microwave oven as described above, wherein an output end of the magnetron 400 is connected to the input interface 230 of the waveguide 200, so as to be suitable for the magnetron 400 to output microwaves to the waveguide.
