Examples of implementation of antenna-feed path multiband antennas based on various layouts are considered. Conclusions are drawn about the advantages and disadvantages of the presented methods.</p>антенно-волноводный трактпоказатель эффективностизеркальная антеннаantenna-feed pathefficiency indexreflector antenna[Korovkin A.E. et al.
