ABSTRACT

The scattering characteristics of the microstrip transmission line fundamental wave on an H-shaped slot resonator in its ground plane with a cross and a symmetric arrangement with respect thereto "dumbbells" was investigated. It is shown that such discontinuity may have two frequencies of resonant interaction with the waveguide transmission line and accordingly possesses properties broadband band-stop filter. The main benefits of filters are their compactness and high attenuation level in a frequency band. The broadband rejection filters with a bandwidth of 3.2-4.5 GHz barriers (35%) and 3.35-4.8 GHz (36%) were modeled, and its scattering characteristics were calculated by transverse resonance technique.
