Abstract

Microwave filter in rectangular dielectric waveguide (GDL-RIS) complete with micro-strip input/output structures (2, 3; 2', 3') obtained through appropriate metallization of an alumina substrate(1) having size 44 x10 x 0,635 mm. The metal coating (6) completely covers the surface rear side of the substrate , where it forms the bottom side of the waveguide and the ground plane for the microstrip lines. The top side of the substrate is metal-coated connecting the waveguide (4) opposite wall and the microstrip lines. The longitudinal side walls of the dielectric waveguide are obtained through metal coating of two grooves (5, 5') of the substrate (1) and then cutting the substrate with diamond saw along the centre line of the grooves. Each input/output structure of the dielectric waveguide is a microstrip line (2, 2') that widens (3, 3') as it approaches the top side wall (4) of the waveguide, acting as tapered transition between the "quasi-TEM" propagation mode of the signal in the microstrip and the dominant mode TE10 in the waveguide, or as reciprocal transition and matching at the same time the impedance seen at the two ends of each tapered transition (3, 3') within the filter operating frequency band. The thickness of the waveguide is drilled by metallized via-holes (F1, F2, F3, F4) having appropriately selected diameter, lambda G/2 apart, operating as a particular kind of inductive element, to shape the desired bandpass response of the filter (fig.2). <IMAGE> <IMAGE>
