Prospects for the Optimization of Parabolic Antenna Reflectors for K and Ka Frequency Bands

Increasing frequencies of perspective space mirror antennas functioning leads to a significant tightening of the requirements for the accuracy and stability of the reflecting surface of the used reflectors, however, the provision of high requirements is technically difficult to implement. Hence, the problem of Pareto-optimal design of parabolic antenna reflectors with a relatively high signal amplification coefficient and minimum requirements to the accuracy of the reflecting surface profile is formulated. Analytical estimates have been obtained for Pareto fronts of various ranks, characterizing the accuracy of the profile of the reflecting surface of the antenna parabolic reflector depending on its diameter and the range of operating frequencies required to ensure a relatively high signal gain.
