Abstract
706,824. Impedance networks. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 17, 1952 [April 20, 1951], No. 9689/52. Class 40 (8) A waveguide system for producing a phase difference between two output waves comprises two waveguides 1, 2 of the dimensions shown on the drawings, the widths a and c varying along the length in at least one of the waveguides in such a manner that a and/or c have extreme values between the input and output ends, e-a0 and c-a0 being small with respect to a0 and in that o1 and o2 are the values of the shaded areas. The phase difference produced by the waveguides is shown to be independent of frequency.
