Abstract

968,919. Aerials; direction finding. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. April 27, 1962 [April 29, 1961], No. 16143/62. Headings H4A and H4D. A wide band aerial, for use in a direction finder (for example a two-path system or a goniometer system), comprises one or more pairs of elements of the " logarithmic periodic " type, the two elements of each pair being oppositely disposed in a common vertical plane as shown to give a cosine polar diagram, Fig. 2 (not shown), similar to that produced by an Adroch aerial having two oppositely connected elements in a vertical plane normal to the plane containing the logarithmic elements. Each logarithmic element comprises a zig-zag conductor constituting a number of resonant elements whose length and spacing varies logarithmically. An arrangement utilizing two orthogonal pairs of elements is disclosed (Fig. 4, not shown).
