Abstract

Technical solution that allows reduce mutual influence of «waveguide‑slot array antenna/twistreflector» system elements due to the use of a microstrip diffraction grating with rectangular elements as a twistreflector is given. The geometrical dimensions of the elements ae calculated in such a way that the diffraction grating converts a falling linearly polarized field into a field with orthogonal polarization at the working frequency band. Polarization characteristics angular dependence of twistreflector in EHF and radiation characteristics of waveguide‑slot array antenna multi‑element in SHF of investigated system was performed using FDTD method. The possibility of the system functioning in both working frequency range with an insignificant mutual influence is shown. The low level of mutual influence is explained by the significant difference in the resonant frequencies being combined.
