摘要: This study presents a new hat feed that is made entirely of metal without using dielectric material. Compared to previous feeds where piece used support the on waveguide, has lower manufacturing cost and higher reliability. In addition, low radiation along feeding which makes vertex plate unnecessary. Therefore bandwidth over reflection coefficient magnitude below -15 dB increased. The been optimised genetic algorithm. A prototype manufactured, measured results are presented verify numerical simulations.
