Abstract

Die vorliegende Erfindung betrifft eine Antenne für funkbetriebene Kommunikationsendgeräte (2). Zur Verwirklichung einer Multibandantenne ist eine planare Inverted-F-Antenne (1) vorgesehen, die in ihrer Größe für eine vorgegebene untere Abstrahl-Frequenz ausgelegt ist, und die in Längsrichtung eine oder mehrere Einkerbungen oder Abstufungen aufweist, mittels derer sich eine oder mehrere geometrische Strecken ergeben, über deren Verlauf sich abstrahlbare Wellen mit einer höheren Frequenz als die vorgegebene untere Frequenz ausbilden.

The invention relates to an antenna for radio-operated communication terminals (2). To implement a multi-band antenna, a planar inverted-F antenna (1) is provided, the size of which is designed for a predetermined lower radiation frequency, and which has one or more indentations or gradations in the longitudinal direction, by means of which one or more geometrical dimensions Routes result, over the course of which radiatable waves are formed with a higher frequency than the predetermined lower frequency.
