Horn excitation dielectric surface wave uniform heating device

The invention discloses a horn excitation dielectric surface wave uniform heating device, which comprises a waveguide horn antenna and at least one dielectric strip arranged at the tail end of a horn mouth of the waveguide horn antenna, and an objective table is arranged above the dielectric strip. According to the technical scheme, microwaves generated by the magnetron form uniform surface waves through the dielectric strip array at the bottom of the microwave oven, and food in the cavity of the microwave oven is uniformly heated, so that the heating uniformity and efficiency of the microwave oven are improved. 本发明公开了一种喇叭激励介质表面波均匀加热装置，包括波导喇叭天线和设置在波导喇叭天线喇叭口末端的至少一个介质条，介质条的上方设有载物台。通过本发明的技术方案，把磁控管产生的微波通过微波炉底部的介质条阵列形成均匀的表面波，并对微波炉腔内的食物进行均匀加热，旨在提升微波炉的加热均匀性和效率。
