Patent number: 9620837Abstract: A bandpass filter for microwave-frequency wave which is frequency tunable, comprises at least one resonator. Each resonator comprises a cavity having a conducting wall substantially cylindrical in relation to an axis Z, and at least one dielectric element disposed inside the cavity. The resonator resonates on two perpendicular polarizations having respectively distributions of the electromagnetic field in the cavity that are deduced from one another by a rotation of 90° and according to one and the same frequency. The wall of the cavity comprises an insert section facing the element having a different shape from a section not situated facing the element. The insert section and the element are able to perform a rotation with respect to one another in relation to the axis Z so as to define at least a first and a second relative position differing by an angle substantially equal to 45° to within 20°.Type: GrantFiled: December 17, 2014Date of Patent: April 11, 2017Assignees: THALES, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, CENTRE NATIONAL D'ETUDES SPATIALESInventors: Hussein Ezzeddine, Aurelien Perigaud, Olivier Tantot, Nicolas Delhote, Stephane Bila, Serge Verdeyme, Damien Pacaud, Laetitia Estagerie

Patent number: 9620836Abstract: A frequency tunable microwave bandpass filter comprises a resonator, including: a cavity with conducting wall substantially cylindrical with axis Z having height H, and partially closed at both ends; and a dielectric element inside the cavity. The resonator resonates at two perpendicular polarizations having distributions of electromagnetic field in the cavity deduced from eachother by 90° rotation. The element rotates about an axis substantially perpendicular to axis Z, between a first and second position. The element comprises a first end wherein: in a first position the element is disposed substantially in a plane perpendicular to axis Z and the center of the first end is disposed at a height in the cavity corresponding substantially to an electric field minimum; and in a second position the element is substantially parallel to Z and the first end is disposed in a plane corresponding to an electric field maximum within +/?30%.Type: GrantFiled: December 17, 2014Date of Patent: April 11, 2017Assignees: THALES, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, CENTRE NATIONAL D'ETUDES SPATIALESInventors: Nicolas Jolly, Aurelien Perigaud, Olivier Tantot, Nicolas Delhote, Stephane Bila, Serge Verdeyme, Damien Pacaud, Laetitia Estagerie
