众所周知,在微波系统的设计中,常需要低过渡衰减的紧凑的波导定向耦合器,而不需要很高的方向性.“十”字型槽交叉波导定向耦合器(图1),虽然具有结构紧凑、方向性
It is well-known that in the design of microwave systems, compact waveguide directional couplers with low transient attenuation are often required without the need for high directivity. "Cross-shaped waveguide cross directional couplers (Figure 1) With a compact, directional
