Abstract

En gruppeantenne innrettet for bruk med en eneste signalmating har en transmisjonslinje orientert hovedsakelig parallelt med et jordplan, der transmisjonslinjen har et antall sekvensielle seksjoner hvor hver sekvensiell seksjon har forskjellig avstand fra jordplanet i forhold til sine umiddelbart tilstøtende sekvensielle seksjoner. Denne transmisjonslinjen med trinnvis eller variert impedans danner en gruppe der seksjonene som er adskilt lenger fra jordplanet blir aktive antenneelementer. Styring av en elektrisk avstand mellom jordplanet og transmisjonslinjen tilveiebringer relativ fasestyring mellom de aktive elementer og derved fasestyrt retningskontroll av gruppeantennen.
