ABSTRACT:
A superconducting patch antenna array, operative at a temperature lower than or equal to that of liquid nitrogen, includes a superconducting mixer comprising at least one non-linear Josephson junction to transform the received high frequency signal to a lower intermediate frequency for purposes of reducing the transmission loss and thereby increasing the antenna performance.
