Unbalanced to balanced broadband impedance transformer

Claim 1

A DEVICE FOR CONNECTING A COAXIAL LINE HAVING A LOW CHARACTERISTIC IMPEDENCE TO A BALANCED LINE HAVING A HIGHER CHARACTERISTIC IMPEDENCE, SAID DEVICE COMPRISING, IN COMBINATION: (A) A BALANCING LOOP HAVING A HOLLOW OUTER CONDUCTOR; (B) A TRANSFORMER LOOP PRODUCING A 1:4 TRANSFORMATION RATIO HAVING A HOLLOW OUTER CONDUCTOR; (C) AT LEAST ONE COMPENSATING SECTION CONNECTION SAID LOOPS THEREBY TO FORM A LOOP ASSEMBLY; (D) MEANS FOR CONNECTING A COAXIAL LINE WITH ONE ELECTRICAL END OF SAID LOOP ASSEMBLY; AND (E) MEANS FOR CONNECTING A BALANCED LINE WITH THE OTHER ELECTRICAL END OF SAID LOOP ASSEMBLY AND INCLUDING INITIAL PORTIONS OF A BALANCED LINE AND A CONNECTION ASSEMBLY INCLUDING TERMINAL PORTIONS FOR CONNECTING SAID INITIAL PORTIONS WITH A BALANCED LINE PROPER; AND WHEREIN SAID DEVICE IS ARRANGED WITH (1) SAID BALANCING AND TRANSFORMER LOOPS BEING OF SUBSTANTIALLY THE SAME SIZE AND ARRANGED CLOSELY TOGETHER IN A MIRROR IMAGE RELATIONSHIP WITH RESPECT TO A PLANE OF SYMMETRY PARALLEL TO THE LOOP PLANES AS DETERMINED BY THE LOOP AXES THROUGH THE SECTIONS OF THE LOOPS, (2) ONE LEG OF A LOOP IN A PLANE BEING A PORTION OF THE BALANCING LOOP AND THE OTHER LEG OF SUCH LOOP BEING A PORTION OF THE TRANSFORMER LOOP, (3) THE END OF SAID LOOP ASSEMBLY DISPOSED ADJACENT THE COAXIAL LINE CONNECTING MEANS HAVING OUTLETS FORMED THEREIN FOR PASSAGE THERETHROUGH OF SAID INITIAL PORTIONS WHICH ARE CONNECTED TO SAID LOOP ASSEMBLY, SAID OUTLETS BEING DEFINED BY OPENINGS IN SAID OUTER CONDUCTORS AND WHICH ARE DISPOSED IN MIRROR IMAGE RELATIONSHIP WITH RESPECT TO SAID PLANE OF SYMMETRY, (4) SAID INITIAL PORTIONS OF SAID OUTLET PROJECTING AWAY FROM EACH OTHER AT RIGHT ANGLES TO SAID PLANE OF SYMMETRY, SAID INITIAL PORTIONS BEING BENT PARALLEL TO SAID PLANE OF SYMMETRY AT A DISTANCE WHICH PRODUCES THE DESIRED CHARACTERISTIC IMPEDANCE AND LEADING TO THE BALANCED LINE CONNECTION ASSEMBLY, AND (5) SAID INITIAL PORTIONS BEING DISPOSED IN MIRROR IMAGE RELATIONSHIP WITH RESPECT TO SAID PLANE OF SYMMETRY WITH THE AXES THEREOF DISPOSED WITHIN THE EQUIPOTENTIAL PLANE OF SAID LOOPS.

Claim 2

A DEVICE FOR CONNECTING A COAXIAL LINE HAVING A LOW CHARACTERISTIC IMPEDENCE TO A BALANCED LINE HAVING A HIGHER CHARACTERISTIC IMPEDENCE, SAID DEVICE COMPRISING, IN COMBINATION: (A) A BALANCING LOOP HAVING A HOLLOW OUTER CONDUCTOR; (B) A TRANSFORMER LOOP PRODUCING A 1:4 TRANSFORMATION RATIO HAVING A HOLLOW OUTER CONDUCTOR; (C) AT LEAST ONE COMPENSATING SECTION CONNECTION SAID LOOPS THEREBY TO FORM A LOOP ASSEMBLY; (D) MEANS FOR CONNECTING A COAXIAL LINE WITH ONE ELECTRICAL END OF SAID LOOP ASSEMBLY; AND (E) MEANS FOR CONNECTING A BALANCED LINE WITH THE OTHER ELECTRICAL END OF SAID LOOP ASSEMBLY AND INCLUDING INITIAL PORTIONS OF A BALANCED LINE AND A CONNECTION ASSEMBLY INCLUDING TERMINAL PORTIONS FOR CONNECTING SAID INITIAL PORTIONS WITH A BALANCED LINE PROPER; AND WHEREIN SAID DEVICE IS ARRANGED WITH (1) SAID BALANCING AND TRANSFORMER LOOPS BEING OF SUBSTANTIALLY THE SAME SIZE AND ARRANGED CLOSELY TOGETHER IN A MIRROR IMAGE RELATIONSHIP WITH RESPECT TO A PLANE OF SYMMETRY PARALLEL TO THE LOOP PLANES AS DETERMINED BY THE LOOP AXES THROUGH THE SECTIONS OF THE LOOPS, (2) ONE LEG OF A LOOP IN A PLANE BEING A PORTION OF THE BALANCING LOOP AND THE OTHER LEG OF SUCH LOOP BEING A PORTION OF THE TRANSFORMER LOOP, (3) THE END OF SAID LOOP ASSEMBLY DISPOSED ADJACENT THE COAXIAL LINE CONNECTING MEANS HAVING OUTLETS FORMED THEREIN FOR PASSAGE THERETHROUGH OF SAID INITIAL PORTIONS WHICH ARE CONNECTED TO SAID LOOP ASSEMBLY, SAID OUTLETS BEING DEFINED BY OPENINGS IN SAID OUTER CONDUCTORS AND WHICH ARE DISPOSED IN MIRROR IMAGE RELATIONSHIP WITH RESPECT TO SAID PLANE OF SYMMETRY, (4) SAID INITIAL PORTIONS OF SAID OUTLET PROJECTING AWAY FROM EACH OTHER AT RIGHT ANGLES TO SAID PLANE OF SYMMETRY, SAID INITIAL PORTIONS BEING BENT PARALLEL TO SAID PLANE OF SYMMETRY AT A DISTANCE WHICH PRODUCES THE DESIRED CHARACTERISTIC IMPEDANCE AND LEADING TO THE BALANCED LINE CONNECTION ASSEMBLY, AND (5) SAID INITIAL PORTIONS BEING DISPOSED IN MIRROR IMAGE RELATIONSHIP WITH RESPECT TO SAID PLANE OF SYMMETRY WITH THE AXES THEREOF DISPOSED WITHIN THE EQUIPOTENTIAL PLANE OF SAID LOOPS.
