摘　　要：波导魔T由于损耗小、功率容量高在微波系统中得到广泛的应用,但其缺点是匹配形式复杂、加工难度高、一致性差。文中提出一种新的波导魔T(H面压窄波导魔T)结构,这种H面压窄波导魔T结构形式紧凑,体积小、重量轻,魔T匹配形式非常简单,仿真计算结果表明,该魔T具备带宽宽、驻波小、隔离度高、幅相分布特性好、功率容量高等优点,能够满足高精度低损耗馈电网络的需要。Waveguide magic T has been widely used in microwave systems due to its low loss and high power capacity.However,its disadvantage is complex matching structure,high processing difficulty and poor consistency.A new waveguide magic T(compact Hplane waveguide magic T)structure is proposed in this paper.This magic T have compact structure,small size,light weight and very simple matching structure.From the result of simulation,this magic T has the advantages of wide bandwidth,low VSWR,high isolation,good amplitude and phase distribution characteristics and high power capacity.It can meet the need of high-precision,lowloss feed network.
