Passive Loop Antenna SAS-565H
The easiest method to avoid antenna saturation for the measurement of high magnetic fields is to use a passive antenna. This 24" (60cm) Passive Loop Antenna is designed with a balanced faraday shield for magnetic field emissions and immunity type measurements. The loop antennas electrostatic shield minimizes the E-field response for a more accurate magnetic field measurement. With emerging technologies like wireless power and possible changes for radiated emission test distances, passive loop antennas are an ideal test solution.
The SAS-565H passive loop antenna covers the 9 KHz to 30 MHz frequency range, has a 1/4-20 thread for easy tripod mounting and comes with individual calibration results per IEEE 291 section 2.2.1

Loop Antennas 20 Hz - 30 MHz
A.H. Systems manufactures a wide variety of loop antennas in the frequency range of 20 Hz to 30 MHz. Loop antennas are primarily used to measure the magnetic field strength at lower frequencies. The small size of these loop antennas has the advantage of convenience in handling, availability of a zero- response orientation, and a simple expression for the voltage produced by a given field strength. At higher frequencies, about above 100 MHz, a loop of practical size may no longer be electrically small and has a significant response to the electric field as well as the magnetic field.
Whether used in a set to measure shielding effectiveness per MIL-STD 285 and NSA 65-6 or individually to satisfy specific requirements, the Loop Antenna is an efficient, low cost solution.
