Patent number: 7457651Abstract: A planar filter has a planar resonator including a conductive region having smoothed contours and supporting a first resonating mode propagating along a first conductive path and a second resonating mode propagating along a second conductive path perpendicular to the first conductive path. The planar filter also has a conductor-free region made in the conductive region and having smoothed contours. The conductor-free region is disposed along a region axis forming an angle with respect to the first conductive path. The conductor-free region causes a perturbation of the symmetry of the planar resonator resulting in a frequency shift of the first and second resonating mode and their mutual coupling.Type: GrantFiled: September 30, 2003Date of Patent: November 25, 2008Assignees: Telecom Italia S.p.A., Pirelli & C.

Patent number: 6946933Abstract: The dielectric loaded cavity for high frequency filters consists of a metal container housing s dielectric block held in position by supporting plates, that also sustains coupling and tuning elements. This invention provides broadband filters, small in size and with low losses. Its high symmetry structure considerably reduces the energizing of spurious modes and furthermore facilitates the design using automatic calculation procedures, on the basis of accurate electromagnetic models.Type: GrantFiled: July 18, 2001Date of Patent: September 20, 2005Assignee: Telecom Italia Lab S.p.A.Inventors: Luciano Accatino, Giorgio Bertin, Mauro Mongiardo

Patent number: 5821837Abstract: A multi-mode, typically triple-mode, cavity (1), for waveguide band-pass filters is disclosed, which cavity requires no tuning or coupling screws and rounded. The cavity comprises a waveguide element such as an iris (IR1) or a waveguide segment (CR2) arranged in a generically eccentric position with respect to the general development of the cavity and in particular to the main axis (Z) of the same. The cavity may be used to make narrowband filters for satellite communications. A filter comprising cavities (1) of the type described can be designed entirely using an electronic computer and requires no calibration procedure.Type: GrantFiled: December 26, 1996Date of Patent: October 13, 1998Assignee: Cselt- Centro Studi e Laboratori Telecomunicazioni S.p.A.Inventors: Luciano Accatino, Giorgio Bertin

Patent number: 5805035Abstract: The cavity has at least one waveguide segment with elliptical cross section whose axes are arranged at a given inclination angle (.alpha.) with respect to the polarization of the incident TE field. Thus a dual-mode cavity is realized, with the ability to let resonate two transverse fields (TE) with polarization planes orthogonal to each other. By adding a waveguide element able to introduce a non-axial discontinuity, a triple-mode cavity is obtained, allowing for an additional longitudinal mode to resonate as well.Type: GrantFiled: December 26, 1996Date of Patent: September 8, 1998Assignee: Cselt-Centro Studi E Laboratori Telecomunicazioni S.p.A.Inventors: Luciano Accatino, Giorgio Bertin

Patent number: 5703547Abstract: Dual-mode cavity of waveguide bandpass filters, which allow the realization of narrow-band filters with very limited transition band and extremely low losses, without tuning or coupling screws or smooth edges. The dual mode cavity is composed of three coaxial sections of waveguide arranged in cascade and provided with irises, of which the two end sections are suited to support two modes with orthogonal polarizations and the intermediate section, consisting of a rectangular waveguide, has its side tilted with respect to the plane on which the irises lie. The whole filter composed of these cavities can be entirely designed by means of a computer and requires no tuning operation.Type: GrantFiled: February 11, 1997Date of Patent: December 30, 1997Assignee: Cselt- Centro Studi E Laboratori Telecomunicazioni S.P.A.Inventors: Giorgio Bertin, Luciano Accatino

Patent number: 4652836Abstract: An integrated microwave oscillator as which the generated frequency is stabilized by a dielectric resonator with high quality factor and stability. The positive feedback is assured not only by the dielectric resonator coupled to a line connected to a terminal of the active device, but also by a microstrip resonator connected in parallel to a second line connected to a second terminal of the active device. The signal generated is extracted from the third terminal of the active device.Type: GrantFiled: February 19, 1986Date of Patent: March 24, 1987Assignee: Cselt--Centro Studi e Laboratori Telecomunicazioni S.p.A.Inventors: Luciano Accatino, Giorgio Bertin
