Abstract :
New configuration of the notch and bandstop filters is proposed and investigated. Here a rejection section is based on a thin slotted H-plane strip that may be considered as a limiting case of a three-slot iris. Such a section forms symmetrical frequency response with very low insertion loss out of the stopband. The results of numerical design and measurement data are given for a 3% notch filter and for 2% three-section bandstop one. In the low-power applications the proposed notch filter is probably the simplest one due to its easy fabrication and a possibility to be incorporated into a waveguide circuit by placing between the waveguide flanges.
