魔T是单脉冲雷达及很多微波组件中的关键元件,它的性能直接影响整机和组件的性能。微带环行电桥是真正的共面结构,但它的频带窄,原因是采用了半波长的传输线作倒相网络,整个微带魔T的尺寸也因此而增大。垂直耦合微带线易于提供所要求的端接匹配阻抗和耦合度,本文用它作微带环行电桥的倒相网络,利用其短路柱作倒相网络结构上的支撑。设计出的魔T类似于宽带环行 Magic T is a single pulse radar and many microwave components in the key components, its performance directly affects the performance of the machine and components. Microstrip ring bridge is a true coplanar structure, but its narrow band, because the use of a half-wavelength transmission line for the inverting network, the entire micro-band magic T size also increased. Vertical coupling microstrip line to provide the required termination impedance matching and coupling degree, we use it as the microstrip loop bridge inverter network, using its short-circuit column for inverting the network structure of the support. The design of the magic T is similar to the broadband ring
