Possibilities of Extending the Stop and Pass Bandwidths of the Microwave Antenna-Filters by Means of a Dielectric Resonant Scatterer

The electromagnetic compatibility (EMC) of the microwave electronic systems (ES) are highly actual and very important. Usually the noise delay is realized via various stop-band filters on the basis of arrays, volume metal resonators, etc. But those possess some drawbacks such as a big mass and relatively considerable dimensions and volume. Effective suppression of the undesirable signals may be achieved using a sole dielectric resonant scatterers (DRS) combined with a rectangular waveguide radiators. Sometimes it is necessary to extend the stop and pass bandwidths of such antenna-filters
