Claim 4

IN A MICROWAVE NETWORK OF THE CHARACTER INCLUDING AT LEAST ONE CIRCUIT ELEMENT WHICH CAUSES A NETWORK TO EXHIBIT A NON-CONSTANT TIME DELAY VS. FREQUENCY CHARACTERISTIC ON MICROWAVE SIGNALS TRAVERSING ALONG A PREDETERMINED SIGNAL PATH THEREIN, THE COMBINATION THEREIN OF A TIME DELAY EQUALIZING NETWORK COMPRISING: A LENGTH OF MICROWAVE TRANSMISSION STRIP LINE CONNECTED IN CASCADE WITH SAID AT LEAST ONE CIRCUIT ELEMENT IN SAID PREDETERMINED SIGNAL PATH OF SAID NETWORK; A FIRST HALF-WAVE LENGTH RESONANT STRIP LINE ELEMENT INDUCTIVELY COUPLED TO SAID STRIP LINE AT A PREDETERMINED LONGITUDINAL LOCATION ON SAID LENGTH OF STRIP LINE AND DISPOSED LATERALLY TO A FIRST SIDE THEREOF IN AN ELECTROMAGNETIC SERIES COUPLED RELATION THEREWITH; AND A SECOND HALF-WAVE LENGTH RESONANT STRIP LINE ELEMENT CAPACITIVELY COUPLED TO SAID STRIP LINE AT SAID PREDETERMINED LONGITUDINAL LOCATION ON SAID LENGTH OF STRIP LINE AND DISPOSED LATERALLY TO THE OPPOSITE SIDE THEREOF IN AN ELECTROMAGNETICALLY SHUNT COUPLED RELATIONSHIP THEREWITH, SAID FIRST AND SECOND HALF WAVE LENGTH RESONANT ELEMENT HAVING PREDETERMINED, SUBSTANTIALLY EQUAL Q''S (LOADED) AND RESONANT FREQUENCIES, WHEREBY SAID SERIES AND SHUNT COUPLED RESONANT STRIP LINE ELEMENTS ARE OF THE CHARACTER TO BE EXCITED BY MICROWAVE ENERGY PROPAGATING ALONG SAID LENGTH OF MICROWAVE STRIP TRANSMISSION LINE IN MODES OF OSCILLATION WHICH ARE IN QUADRATURE PHASE RELATIONSHIP WITH EACH OTHER.

Claim 5

A MICROWAVE STRIP LINE, TIME DELAY EQUALIZING CIRCUIT FOR USE IN COMBINATION WITH A MICROWAVE NETWORK WHICH WITHOUT EQUALIZATION EXERTS ON MICROWAVE SIGNALS PROPAGATED ALONG A PREDETERMINED SIGNAL PATH THEREOF A NON-CONSTANT TIME DELAY VS. FREQUENCY CHARACTERISTIC, AND COMPRISING: A LENGTH OF MICROWAVE TRANSMISSION STRIP LINE CONNECTED IN CASCADE WITH SAID PREDETERMINED SIGNAL PATH; AND A CLOSED LOOP STRIP LINE RESONATOR DISPOSED COPLANARLY WITH SAID LENGTH OF STRIP LINE AND HAVING A PORTION OF ITS PERIMETER DISPOSED CONTIGUOUSLY TO, IN A PREDETERMINED ELECTRO-MAGNETIC COUPLING RELATIONSHIP THEREWITH, SAID STRIP LINE RESONATOR HAVING A PREDETERMINED RESONANT FREQUENCY FOR TWO FUNDAMENTAL MODES OF OSCILLATION AROUND SAID CLOSED LOOP RESONATOR FOR EQUALIZING SAID NON-CONSTANT TIME DELAY CHARACTERISTIC OF SAID NETWORK, SAID MODES OF OSCILLATION BEING OF EQUAL FREQUENCY AND Q (LOADED) AND BEING IN QUADRATURE PHASE RELATIONSHIP WITH RESPECT TO EACH OTHER, ONE OF SAID MODES BEING ELECTRICALLY COUPLED TO SIGNALS PROPAGATING ALONG SAID LENGTH OF MICROWAVE TRANSMISSION STRIP LINE AND THE OTHER BEING MAGNETICALLY COUPLED THERETO.

Claim 6

A MICROWAVE STRIP LINE, TIME DELAY EQUALIZING CIRCUIT FOR USE IN COMBINATION WITH A MICROWAVE NETWORK WHICH WITHOUT EQUALIZATION EXERTS ON MICROWAVE SIGNALS PROPAGATED ALONG A PREDETERMINED SIGNAL PATH THEREOF A NON-CONSTANT TIME DELAY VS. FREQUENCY CHARACTERISTIC, AND COMPRISING: A LENGTH OF MICROWAVE TRANSMISSION STRIP LINE CONNECTED IN CASCADE WITH SAID PREDETERMINED SIGNAL PATH; AND A CLOSED LOOP STRIP LINE RESONATOR DISPOSED COPLANARLY WITH SAID LENGTH OF STRIP LINE AND HAVING A PORTION OF ITS PERIMETER DISPOSED CONTIGUOUSLY TO, IN A PREDETERMINED ELECTRO-MAGNETIC COUPLING RELATIONSHIP THEREWITH, SAID STRIP LINE RESONATOR HAVING A PREDETERMINED RESONANT FREQUENCY FOR TWO FUNDAMENTAL MODES OF OSCILLATION AROUND SAID CLOSED LOOP RESONATOR FOR EQUALIZING SAID NON-CONSTANT TIME DELAY CHARACTERISTIC OF SAID NETWORK, SAID MODES OF OSCILLATION BEING OF EQUAL FREQUENCY AND Q (LOADED) AND BEING IN QUADRATURE PHASE RELATIONSHIP WITH RESPECT TO EACH OTHER, ONE OF SAID MODES BEING ELECTRICALLY COUPLED TO SIGNALS PROPAGATING ALONG SAID LENGTH OF MICROWAVE TRANSMISSION STRIP LINE AND THE OTHER BEING MAGNETICALLY COUPLED THERETO.
