摘要： An antenna includes a plurality of superconducting quantum interference device (SQUID) arrays on a chip, and a printed circuit board (PCB) formed with a cutout for receiving the chip. The PCB is formed with a set of coplanar transmission lines, and the chip is inserted into the cutout so that each said transmission line connects to a respective SQUID array. A cryogenic system can cool the chip to a temperature that causes a transition to superconductivity for the SQUID arrays. A thermal radome can be placed around the chip, the PCB and the cryogenic system to maintain the temperature. A DC bias can be applied to the SQUID arrays to facilitate RF detection. The SQUID array, chip and CPW transmission lines can cooperate to allow for both detection of said RF energy and conversion of said RF energy to a signal without requiring the use of a conductive antenna dish.

摘要： A device in accordance with several embodiments can include a plurality of N Superconducting Quantum Interference Devices (SQUIDs), which can be divided into a plurality of sub-blocks of SQUIDs. The SQUIDs in the sub-blocks can be RF SQUIDs, DC SQUIDs or bi-SQUIDs. The sub-blocks can be arranged in a plurality of X tiers, with each Ti tier having a different number of sub-blocks of SQUIDs than an immediately adjacent Ti tier. Each Ti tier can have the same total bias current; and can have SQUIDs with different critical currents and loop sizes, with the different loop sizes on each tier having a Gaussian distribution of between 0.5 and 1.5 (or a random distribution). Additionally, the Arrays can be configured as three independent planar arrays of SQUIDs. The three planar arrays can be triangular when viewed in top plan, and can be arranged so that they are orthogonal to each other.
