Title: Reflector antenna having supports in the beam path which produce secondary radiation
Inventor: THIELEN HERBERT DIPL PHYS
IPC: H01Q19/02
Filed: 1981-01-14
Abstract: The invention relates to a reflector antenna having supports in the beam path which produce secondary radiation. This secondary radiation, which causes an increased sidelobe in the polar diagram, is intended to be prevented according to the invention in that the supports (8) are curved by an amount which deviates from a straight line by up to a plurality of wavelengths, in order to change the phase of the surface currents, which are induced on the supports, in a plane which is defined by the reflector axis and the two end points of the supports. The amount of deviation from a straight line is approximately 3-9% of the support length. The interference radiation caused by the supports was around 6 dB less in the case of an exemplary embodiment according to Fig. 3 than when straight supports were used and, in addition, takes place in a different direction. <IMAGE>
