摘要
文中提出了一种新型的波导到双带状线的过渡结构。通过多层印制板、反射腔、金属化通孔形成的约束腔体和"L"型波导构成一个准封闭的电磁通道,实现从波导到双带状线的过渡转换。仿真结果表明,在9GHz到11.5GHz的频率范围内,该过渡结构的插入损耗小于3.4d B,驻波小于1.4,相对带宽大于25%,且能实现从波导至双带状线的等幅反相过渡转换。
In this paper, a novel waveguide-to-dual-stripline transition is proposed. The electric field in rectangular waveguide can be transmitter to a dual-stripline by a quasi-enclosed channel consists of multilayer Printed Circuit Board, a reflection cavity, a cavity made from a series of shorting via and an L-shaped waveguide. The simulated results show that the insertion loss less than 3.4d B, VSWR less than 1.4 in the range of 9-11.5GHz, the relative bandwidth is more than 25%. The electric field can transmit with equally amplitude and anti-phase, exhibits good consistency in both magnitude and phase between two output ports.
