A system is provided for detecting a radio frequency signal. The system includes a dielectric platform, a first SQUID array, a second array of SQUIDs and a processing component. The dielectric platform has a first planar surface and a second planar surface that is disposed at an angle relative to the first planar surface. The first array of SQUIDs is disposed on the first planar surface and can output a first detection signal based on the radio frequency signal. The second array of SQUIDs is disposed on the second planar surface and can output a second detection signal based on the radio frequency signal. The processing component can determine a first plane from which the radio frequency signal is transmitting based on the first detection signal and the second detection signal.
