Abstract

781,882. Impedance matching. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 10, 1955 [Nov. 10, 1954], No. 32609/54. Class 40 (8). In order to improve the band-width of a bar and post waveguide to coaxial line transformer the impedance of the bar 8 is made non- uniform along its length as by a local thickening 8a at the centre. The Specification gives dimensions and frequency-impedance curve, for two practical embodiments.
