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.Antenna for handheld mobile phones with reduced radiation load for the user. The antenna of the hand-operated mobile telephone (1) is a monopole (6) designed as a monopole, the electrical length of which is X / 2. hand-operated mobile phone (1) housing. In addition to minimizing the radiation load for the user, an improvement in the electrical properties of the rod antenna (6) is also provided. This effect, which produces a higher transmitting power, is due to the fact that the invention does not show any particular absorption of the radiated power in the user's head.
