Abstract
1,227,559. Matching impedances. WESTERN ELECTRIC CO. Inc. 16 July, 1968 [19 July, 1967], No. 33781/68. Heading H1W. A strip line 12 is matched to a waveguide 10 by means of a localized reactance which resonates with part of the distributed reactance of the line. The strip line may be of the two conductor or three conductor type. A portion of the line conductor 12 and dielectric substrate extends into the guide 10 with the plane of the strip either parallel to (as shown) or at rightangles to the narrow sides. Capacitive reactances provided by one or more cross-pieces 17, 18, 21, 22 resonate with the inductive reactance of the strip at frequencies within the band of interest. In addition, the capacitance afforded by the gap a resonates with part of the inductance of the line. These resonances are distributed to provide broad-band tuning. Instead of, or in addition to, cross-pieces, the strip may be formed with one or more notches which provide localized inductance. It is stated that tuning may be improved by reactances outside the waveguide provided they are within a distance of one quarter-wavelength from the waveguide. The waveguide may be terminated by a piston (not shown).
