摘　　要：随着微波馈源的不断发展,传统波导体系已经很难满足如今的天线需求,介质加栽技术逐渐应用到馈源喇叭的设计当中。本文分析了金属圆波导内填充2层不同介电常数介质结构,将2层介质作为导波结构,推导了2层介质的传播模式。给出金属波导内填充2层介质这种导波结构的模解序,并画出不同模式的场分布图,对实际设计具有理论指导意义。With the rapid development of the feeding system of the antenna,traditional feeding system cannot satisfy the needs any more.Dielectric-rod loaded feeds are used in more feeding system.This paper presents the broadcast mode of double layer dielectric rod filled waveguide.The analytical solution of broadcast modes are obtained.The figures in this paper show the distribution of electric fields of different modes and some characters of double layer dielectric rod filled waveguide..This paper provide the guidance for design.
