六端口技术的创始人G.Engen提出了最佳六端口电路的设计准则,但没能提出符合设计准则的实际电路.本文按照G.Riblet的五端口电路的设计思想,提出了一种结构紧凑的波导型六端口电路,它符合最佳电路设计准则.文中给出了设计公式和在三厘米波段的数值计算实例. G.Engen, the founder of six-port technology, proposed the design criteria of the best six-port circuit, but failed to put forward the actual circuit that meets the design criteria.In this paper, according to G.Riblet’s five-port circuit design idea, a compact Waveguide type six-port circuit, which meets the best circuit design criteria.The paper gives the design formula and numerical examples in the three centimeter band.
