Tunable passive magnetic transmitting loop antenna. Designed to emit magnetic fields of very high field strength at frequencies from 10 kHz up to 30 MHz. With monitoring loop HFRAE 5163 to control the generated field strength.

The antenna is designed according to the following test methods: VG95373- 13:2008-11 and VG95373- 23:2008-11 to test electronic equipment against radiated susceptibility.

ISO 14708-3 chapter 27.104 to test implantable neurostimulators against magnetic fields.

Functionality

The HFRA SF02G is a passive magnetic loop antenna. Switch-able capacitors allow tuning the transmitting loop from 10 kHz up to 30 MHz. The selection of the most suitable capacitor values is performed automatically. The operator can manually tune the antenna to a requested frequency.

Benefits

Antennas tuned up to resonance generate the highest possible field strength from the given input power. Non-matched antennas have one main-resonance corresponding to the mechanical dimension of the loop. The tunable resonance of the HFRA SF02G allows providing the required field strengths of the test method SF02G with moderate input power. By its broadband high efficiency, it allows performing the test in the complete frequency range from 10 kHz to 30 MHz without any change of the setup.
