DEFINITION

Classification: 315/39.65

(under subclass 39.51) Devices wherein an electrode or portion thereof is formed so as to provide a plurality of distributed impedance structures, the geometrical configuration or the inductance and the capacitance of at least one of the structures being substantially different from the geometrical configuration or the inductance and capacitance of another of the structures.

(1) Note. The different distributed impedance structures may be designed to operate at different frequencies, or to eliminate undesired modes of operation, or for other purposes.

(2) Note. This subclass does not include such distributed impedance structures which are only incidentally of different size or which operate at different undesired frequencies and which may be provided with strapping or other means to make all the structures operate at the same frequency or to reduce undesired modes of operation. For such excluded subject matter, see the other subclasses under subclass 39.51, especially subclass 39.69 for the devices with strapping.

(3) Note. This subclass includes the structure of the electrode, per se, which is provided with the distributed impedance structures of different impedances.

39.61, for devices under subclass 39.51 which have a movable tuning element which may be moved to and from or within the distributed impedance structures to vary the parameters of the structure.
