Abstract

En antenne har en elektromagnetisk interferensundertrykker (3) som omfatter et sammensatt magnetisk element som inneholder mykt magnetisk pulver med et oksidfilmlag og som dekker en del av periferien til antennen. Det er å foretrekke at den elektromagnetiske interferensundertrykkeren dekker en side eller en halvdel av periferien til antennen. Antennen kan omfatte en første antennedel (10) skyvbart holdt av et hus til et radioapparat, og en annen antennedel (20) forbundet til en ende av den første antennedelen. I dette tilfellet er den elektromagnetiske interferensundertrykkeren arrangert i minst en av den første og den andre antennedelen. Den første antennedelen er skyvbart holdt av en holderdel (4) fast festet til huset til radioapparatet. En stopperdel (5) er fast festet til en ende til den første antennedelen for å virke som matedel for den første antennedelen når antennen blir trukket ut. Den andre antennedelen er forbundet til den andre enden av den første antennedelen via en hylsedel (6).
