Abstract

Es wird eine magnetischen Loop-Antenne angegeben, die ohne Kopfkapazität geringe Abmessungen aufweist. Hierzu sind Abschnitte eines die Antenne bildenden Leiterstückes (10), dessen Länge mindestens das 1,5-Fache des Umfanges der Antennenfläche A beträgt, so eng benachbart geführt, daß sich eine magnetische Verkopplung der Leiterabschnitte (12) ergibt.

Figure 00000001
A magnetic loop antenna is specified which has small dimensions without head capacity. For this purpose, sections of a conductor piece (10) forming the antenna, the length of which is at least 1.5 times the circumference of the antenna area A, are guided so closely adjacent that there is a magnetic coupling of the conductor sections (12).
