Abstract

En sirkulator (5) omfatter første og andre koplere (10,20). Nevnte første og andre koplere (10,20) er koplet ved hjelp av første og andre transmisjonslinjer (8,9). Første og andre magnetiske felt (28,29) er tilveiebragt kryssende henholdsvis nevnte første og andre transmisjonslinjer (8,9). I en eksempelvis utførelsesform er de magnetiske felt (28,29) i alt vesentlig parallelle med og innenfor et plan definert av nevnte første og andre transmisjonslinjer (8,9).
