Abstract
An assembly and a method is provided for coupling a microstrip circuit to a cavity resonator. The assembly includes a substrate, a microstrip circuit fabricated on one side of the substrate plate, a ground plane fabricated on the other side of the substrate plate and a cavity resonator. The microstrip is coupled to the cavity resonator by a slot fabricated in the ground plane and a planar radiator disposed between the ground plane and the cavity resonator. The assembly produces a resonator that can operate for frequencies in the range of 1-100 GHz in a simplified and less expensive manufacturing process.
Claims6
An assembly for coupling a microstrip circuit to a cavity resonator, said assembly comprising:
- a substrate plate;
- a microstrip circuit disposed on one side of said substrate plate;
- a ground plane disposed on the other side of said substrate plate;
- and
- a cavity resonator coupled to the microstrip circuit by means of a slot disposed in said ground plane and a planar radiator disposed between said ground plane and said cavity resonator.
A method for coupling a microstrip circuit to a cavity resonator comprising the steps of:
- a) fabricating the microstrip circuit on one side of a substrate plate;
- b) fabricating a ground plane on the other side of said substrate plate;
- c) fabricating a slot in said ground plane;
- (d) coupling the microstrip circuit to the cavity resonator by means of said slot fabricated in said ground plane at said step (c);
- and
- e) disposing a planar radiator between said ground plane and the cavity resonator.
