The application research of micro-strip filter in millimeter-wave frequencies

Micro-strip filter is a filter widely used in microwave circuit, but in millimeter-wave frequencies, some problems as performance degradation and impossible processing will appear on model and design of conventional type. The thesis gives an example of making EHF frequency band-pass filter through the modified stub line's filter model, and provides stimulation optimization process and test result, it proves the accuracy of the design and expands the application scope of micro-strip filter in millimeter-wave.
