  • Microwave microstrip filter with U-shaped linear resonators having centrally located capacitors coupled to ground
    Patent number: 4578656
    Abstract: A microwave filter comprising linear resonators makes use of proximity-coupled conductors situated on the first surface of a substrate of dielectric material, whose second surface parallel to the first surface is metallized to form a ground plane, in order to form the resonators. The extremities of each conductor are connected to the earth plane and the center of each conductor is equally connected to the earth plane via at least one capacitor.
