<p>Embedded, coupled, shaped waveguide resonators having conductive walls sandwiched between two fired green tape stacks, said conductive walls having apertures therein whose size and location determine the degree of coupling. These waveguides are made by forming openings in a first green tape stack (12), defining walls (18) and apertures (19) therein, mounting a second green tape stack (23) having a conductive layer (20) thereon thereover and firing the assembly. E-plane probes (22) are inserted in openings (14) in the second green tape stack and connected to microstrip transmission lines (24) on an external surface of this green tape stack.</p> |
