Abstract

In this paper simulated and measured characteristics of an optimized smooth-walled spline-profile horn for two-dimensional multibeam focal plane array at RATAN-600 radio telescope are presented. The measured -10dB beamwidth is less than 45⁰ in the H- and E-planes. The measured side-lobe levels of the radiation pattern are less than -18dB in the both principal planes. The measured input reflection coefficient is better than -21dB in the frequency range 30GHz - 38GHz. The experimental results are in good agreement with simulated ones.
