Waveguide slot array heater designed by using Taylor function synthesis method

Abstract

The invention relates to a waveguide slot array heater designed by using a Taylor function synthesis method, and belongs to the technical field of microwave heating. The antenna comprises a cylindrical resonant cavity, a curved waveguide and a waveguide feed source, wherein the curved waveguide surrounds the cylindrical resonant cavity and is provided with a gap. Microwave energy generated by the magnetron is fed into the curved waveguide through the feed port to form standing waves, and the energy enters the cylindrical resonant cavity through waveguide slot radiation and is absorbed by materials in the cylindrical resonant cavity, so that the heating effect on the materials is achieved. According to the heating method, the phenomena of sparking and scorching caused by too high heating energy of the magnetron are avoided; the gap array designed by using the Taylor function synthesis method can enable the electric field fed into the cylindrical resonant cavity to be more uniform, and the material can achieve a more uniform heating effect. Therefore, the heating device has the characteristics of simple structure, low cost, high coupling efficiency between the feed port and the cylindrical cavity, larger cavity volume, high Q value, greener and more efficient microwave heating, energy conservation and the like.
