Definitions

  • Omnidirectional antennae of the mentioned type are known and are required, for example, in aviation and space flight, to communicate by signals with a missile rotating about its longitudinal axis, for example.
  • a missile rotating about its longitudinal axis, for example.
  • Such a missile must have an antenna which, in a plane normal to its longitudinal axis, has a circ ular radiation characteristic.
  • the procedure hitherto has been to arrange, on the surface of such a cylinder, the largest possible number of individual radiators.
  • Such an antenna system consisting of a large number of individual radiators, has, however, and precisely for applications in space technology, substantial disadvantages.
  • This invention relates to omnidirectional antenna of the type including plural individual radiators arranged on the surface of a preferably cylindrical body whose diameter is large relative to the operating wave length of the antenna and, more particularly, to an improved and simplified omnidirectional antenna of this type.
  • this problem is solved, with several individual radiators of an omnidirectional antenna and arranged on the surface of a preferably cylindrical body whose diameter is large relative to the operating wave length of the invention, by providing that the respective polarization directions of peripherally adjacent individual radiators are perpendicular to each other, and that the respeclive radiation patterns of individual radiators overlap in the range of their respective half powers on 3 db.-points.
  • Still another object of the invention is to provide such an omnidirectional antenna in which the radiating energy of the overlapping radiation patterns of adjoining individual radiators add to each other so that an approximately ideal circular radiation characteristic of the entire antenna system is attained irrespective of the magnitude of the ratio of the diameter of the carrier to the wave length.
  • a further object of the invention is to provide such an omnidirectional antenna using individual radiators in the form of circularly or elliptically polarized helical radiators with adjoining individual radiators being polarized in the opposite sense of rotation.
  • Another object of the invention is to provide such an omnidirectional antenna in which the individual radiators are designed as horn radiators or as dipole radiators.
  • FIG. 4 is a graphical illustration of the radiation pattern of antenna systems embodying the invention.
  • FIGS. 2 and 3 closely resemble that of FIG. 1.
  • the horn radiators of FIG. 1 are replaced by individual dipole radiators, such as the dipole radiator 2' which is polarized parallel to a diameter of cylinder 1 and the dipole radiator 3' which is polarized parallel to the axis of cylinder 1.
  • the individual radiators are helical radiators, and the respective elliptical polarizations of adjacent radiators have opposite senses of rotation.
  • the helical radiator 2 is polarized clockwise and the helical radiator 3" is polarized counterclockwise. Since each elliptically polarized wave can be split up into two mutually perpendicular linear polarized waves, polarized helical radiators, which are polarized in the opposite sense of rotation, can also be considered as being radiators which are polarized perpendicularly to each other.
  • Antenna embodying 2, 4 and 6 individual radiators are of special interest since an antenna system with too large a number ofindividual radiators would have part of the disadvantages of known antenna of this type.
  • Act half power width Act of the radiation patterns of the individual radiators, there results, depending on the number n of individual radiators contemplated on the antenna carrier, the following value: Aer/degrees 360/n.
  • the improvement claimed in claim 1 in which the individual radiators have elliptic polarizations and the respective elliptic polarizations of peripherally adjacent individual radiators are polarized in the opposite sense of rotation.
