Characteristics of Radio Telescopes with Multielement Microstrip Focal Arrays

Abstract

We calculate beam patterns (BPs) and power characteristics of radio telescopes in the multibeam regime with the use of different types of microstrip focal arrays. A “terrace” design of focal array for illumination of the asymmetric secondary mirror of the RATAN-600 radio telescope and a symmetric paraboloid dish is proposed. Ways for optimization of this type of array are considered. Characteristics of a radio telescope with a millimeter-wave planar circularly polarized focal array are calculated. Some applications of multibeam microstrip focal arrays are considered.
