基于波导缝隙辐射器的频率控制分区加热研究
Research on Frequency-controlled Zonal Heating Based on Waveguide Slot Radiator
摘要
Abstract
Most of the existing microwave zonal heating technologies are realized by using phased array technology,which are costly and complex.A two-zone heating system based on waveguide slot antenna is pro-posed,which can realize frequency-controlled two-zone heating inside the cavity at 2.3 GHz and 2.65 GHz.Firstly,a waveguide slot radiator is designed to radiate microwave energy from two different gaps at different fre-quencies.Then,an array of two slit radiators is used to enhance the zonal focus.And finally,a multi-physics model is established to verify the feasibility of using waveguide slot emitter to directly realize two-zone heating inside the cavity at different frequencies.Compared to phased array systems,the proposed system simplifies the structures and process steps,and reduces costs.关键词
