Abstract
867,339. Aerials. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Sept. 15, 1959 [Nov.18, 1958], No. 37139/58. Class 40(7) An aerial giving hemispherical "cover" for transmission or reception over a large bandwidth comprises two tapered coil feeders 1, 1<SP>1</SP> with radiating elements 3, 3<SP>1</SP> attached every quarter turn. The coil pitch decreases from base to apex in a way which may be logarithmic and the electrical length of each element 3, 3<SP>1</SP> is equal to that of the quarter turn at the middle of which it is attached. An earthed conducting surface may be provided inside and parallel to the imaginary surface in which the coils lie. In a modification one coil is omitted.
