本文提出了一种利用腔变换特性耦合平面波导（H面）TE_（10）n/TEn_（01）模腔滤波器的新方法。这种方法被示出为提供实现的椭圆函数响应的平面波导腔结构，虽然这些配置专门表现出磁性虹膜耦合。此外，在任意滤波器特性的设计中的灵活性基本上被扩展为这类滤波器。通过一个毫米波五极点伪椭圆函数滤波器的设计，验证了该方法的有效性。
A new coupling method based on the utilisation of cavity transfonnation properties is established for planar waveguide (H-plane) TE10n/TEn01 mode cavity filters. This method is shown to provide the realisation of elliptic function responses by planar waveguide cavity structures, although these configurations exclusively exhibit magnetic iris couplings. Moreover, the flexibility in the design of arbitrary filter characteristics is essentially extended for this class of filters. The approach is verified by a five-pole pseudo elliptic function filter design for the millimetre wave band.
