Multifunctional Reflector Antenna Feeds

In this paper the design of multifunctional reflector antenna feeds and the methods for their radiation patterns calculation is considered. Reflector antennas (RA) have large gain factor and receive in radio relay, troposphere and satellite radio systems. Multifunctional RA must operate in several separated frequency bands (multiband), on linear and/or circular polarization at each frequency band in transmitting and receiving modes with polarization operating control (all polarized)
