Abstract
En skiveformet reflekteringsplate (3) for å reflektere en elektrisk bølge sendt ut av en åpning (la) av en sirkulær bølgeleder (1) blir plassert på et sted like overfor åpningen (la) av den sirkulære bølgeleder (1), og en ringformet bølgeleder (4) for å forme utstrålingskarakteristikken av den elektriske bølge reflektert av den skiveformede reflekteringsplate (3) til en rotasjonssymmetrisk utstrålingskarakteristikk anbrakt rundt perimeteren av den skiveformede reflekteringsplate (3). Selv når mange spor (4a) må anordnes for at den elektriske bølge får en rotasjonssymmetrisk utstrålingskarakteristikk, blir det følgelig ikke nødvendig å øke størrelsen av den skiveformede reflekteringsplate (3) i retningen av dens radius. Av denne årsak øker ikke nærværet av en sub-reflektor sidelobenivået og vil ikke forårsake en reduksjon i forsterkningsfaktoren og følgelig kan en høy forsterkningsfaktor oppnås og en reduksjon av tverrpolarisering kan utføres og en reduksjon av sidelobenivået kan utføres.
