Abstract
We introduce Superconductive Quantum Arrays and propose to use these structures as active Electrically Small Antennas (ESA). Several prototypes of the active ESA were fabricated using Nb process with a critical current density of 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/μT was observed for the ESA prototype containing 560 cells.
