Abstract

Es wird ein Antennenkern bestehend aus einem biegsamen Paket aus mehreren länglichen weichmagnetischen Streifen (1) aus einer amorphen oder nanokristallinen Legierung vorgestellt. Bei diesem Antennenkern werden die Streifen jeweils voneinander durch eine elektrisch isolierende Folie (2) getrennt. Die amorphe oder nanokristalline Legierung weist einen Magnetostriktionswert λs im Bereich von +4 . 10-6 bis -4 . 10-6 sowie eine lineare B-H-Schleife auf. Die Induktivität L des Antennenkerns ändert sich bei 60 kHz bei einer mittigen Verbiegung um 25 % seiner Länge um weniger als 10% und die Güte Q des Antennenkerns ist ≥ 10 bei 60 kHz.
