Title: Improvements in or relating to antenna
IPC: H01Q19/17
Filed: 1948-02-27
Abstract: 656,852. Directive radio systems. DEPARTMENT OF COMMERCE, DIRECTOR OF THE OFFICE OF TECHNICAL SERVICES OF. Feb. 27, 1948, No. 5948. Convention date, July 9, 1945. [Class 40 (vii)] An antenna system comprises a plurality of equally-spaced coplanar radiation sources, a parabolic reflector for reflecting the energy radiated therefrom and means for adjusting the amount of energy radiated from each of the sources. Such an antenna system is of use for transmission and reception in an aircraft radar system and may be adjusted to give a cosec<SP>2</SP> # radiation pattern over an angle of 30 to 40 degrees, as shown at 11 (Fig. 1). Such a pattern enables echoes of substantially equal intensity to be obtained from an object 12 on the earth's surface at whatever angle of depression 6 it happens to be within the pattern. In one embodiment of the system a magnetron oscillator 20 is connected to waveguide 19 which is provided with a series of radiators 18 equally spaced and in the focal plane of the paraboloidal reflector 17. The lowest radiator is on the axis of the reflector and the other radiators placed at intervals of 2/ 3  A above it to produce a cosec<SP>2</SP> pattern covering about 30 degrees. For such a pattern the radiator next to the axis radiator is arranged to radiate half the energy of that radiator, the next a third, and so on. The reflector aperture is preferably large compared with the length of the array. If desired the system of Fig. 4 may be mounted for scanning in azimuth. The radiators may comprise dipoles energized by probes projecting into waveguide 19 by an adjustable length, Figs. 6 and 7 (not shown).
