  We introduce Superconductive Quantum Arrays (SQAs) and propose to use these
structures as active Electrically Small Antennas (ESA). Several prototypes of
the active ESA were fabricated using Nb process with critical current density
4.5 kA/cm2 and experimentally evaluated. The magnetic field to voltage transfer
function linearity up to 70 dB was measured, and transfer factor dV/dB up to
6.5 mV/{\mu}T was observed for the ESA prototype containing 560 cells.
