Abstract (en)

The antenna arrangement consists of an antenna bearer (2) holding three frame antennas (11-13) arranged in mutually orthogonal pairs engaged within each other. The antenna bearer is made in one piece and each frame antenna consists of a primary coil and a secondary coil. Each frame antenna has the same oval shape and the secondary coils have more windings than the primaries.

Abstract (de)

Zur Erzeugung eines quasi-isotropen Magnetfeldes wird eine Antennananordnung (1) vorgeschlagen, die aus einem einstückigen Antennenträger (2) mit drei paarweise zueinander orthogonal angeordneten Rahmenantennen (11,12,13) mit je einer Primär- und Sekundärwicklung (17,18,19) gebildet wird. Die Sekundärwicklungen sind offen. Durch die ovale Form der Rahmenantennen ergibt sich einerseits eine geringere Bauhöhe und andererseits kann durch dadurch ein quasi-isotropes Magnetfeld erzeugt werden. <IMAGE>
