Design of waveguide E-plane hybrid metal insert filters for millimeter-wave application

Single and double E-plane metal insert irises are analyzed via Mode-Match-Method (MMM), and the position of the double irises is determined first, then single/double/hybrid metal insert filters are designed using the theory of network synthesis, the result demonstrates that hybrid metal insert filte...

Description
Summary:Single and double E-plane metal insert irises are analyzed via Mode-Match-Method (MMM), and the position of the double irises is determined first, then single/double/hybrid metal insert filters are designed using the theory of network synthesis, the result demonstrates that hybrid metal insert filter is easier to fabricate because of its reasonable iris lengths. At last, the above three types of filters are analyzed by MMM, the result demonstrates that hybrid metal insert filter has better transmission characteristics than the single/double metal insert filter. The MMM results are also verified by the results of CST software.
