Abstract

Antenne for håndbetjente mobiltelefoner med redusert strålingsbelastning for brukeren. Antennen for den håndbetjente mobiltelefonen (1) er en som monopol utformet stavantenne (6), hvis elektriske lengde er X/2, Idet en koakslallednlng (4), som et stivt ikke-strålende element, er anordnet mellom stavantennen (6) og den håndbetjente mobiltelefonens (1) hus. Ved siden av å minimalisere strålingsbelast- ningen for brukeren tilveiebringes også en forbedring av de elektriske egenskapene til stavantennen (6). Denne effekten, som bevirker en høyere sendeeffekt, kommer av at det ved oppfinnelsen ikke opptrer noen spesiell absorpsjon av den utstrålte effekten l brukerens hode.
