Slot-Line UWB Bandpass Filters and Band-Notched UWB Filters
Slot-line ultra-wideband (UWB) bandpass filters and band-notched UWB filters are presented for UWB systems. Three types of slot-line multimode resonators are proposed and studied. Microstrip feed lines are used to realize the desired strong external coupling in a simple manner. By properly allocating the resonant modes of resonator and external coupling, UWB bandpass filters have been realized. Next, microstrip resonators, i.e., open-loop resonator, stub-loaded dual-mode resonator, and triangular dual-mode ring resonator, are loaded to the slot-line; notched bands are realized in the UWB passbands. The design methodology has been verified by the measured results.
