Patent DE-3006750-A1 (DE)
Title: Low attenuation phase shift arrangement - is for microwave antenna feed conductors, and uses internal field loading rods having variable length and position
Inventor: SCHUEGRAF EBERHARD DIPL ING
IPC: H01P1/18
Filed: 1980-02-22
Abstract: Based on the theory of field displacement by a longitudinally oriented rod in a hollow rectangular or trapezoid conductor, it is possible to build a phase shft device. With the rod in the centre area a phase lead of about 30 deg. is obtained compared with the empty conductor. With the rod close to a side wall a phase leg of about 18 deg. occurs. A basic phase corrector device therefore consists of a length of hollow conductor (1) in which is arranged a metal wire (2') surrounded by a nonconductive sheath (2). Handling rods (3) made of ceramic permit the rod to be supported and transversally moved. To reduce the frontal reflection losses the wire (2') may be made of several telescopically movable tube sections drawn out in quarter wave length steps. Alternatively, the wire rod may be tapered to a pin point. The asymmetric extent of the phase shift in the leading and lagging directions respectively can largely be corrected by making the hollow conductor of trapezoidal cross section and the transversally movable rod (2) of rectangular cross section with its smaller dimension placed in line with the longer axis of the trapezium.
