Abstract (en)

[origin: EP0446108A1] The invention relates to a dielectric resonator. <??>This resonator is of the type comprising a pattern of metallic microwave strips (A) arranged on a dielectric substrate of high relative permittivity and of annular general shape provided with a slot (1). It is characterised in that it comprises a negative-feedback loop circuit (B) including an active element (8) such as a transistor. <??>The invention is usable for example in band-stop or band-pass filters. <IMAGE>
