Abstract: | Sets of bow-tie antennas, used in a single emitter-receiver near-field configuration and in array configuration, have been
studied to be used as wireless means to transmit 8–12 GHz microwave signals from the cold stage of a cryogenic system to a
room-temperature processing unit. Indeed, the absence of heat conduction allows increasing the performance of cryogenic systems
and open the way to multichannel microwave systems that are necessary for imagers. Transmission loss has been found to be
lower than 3 dB over a 1.5 GHz bandwidth while crosstalk in the array configuration is kept below −20 dB when antennas are
located at around 90 mm transversally from each other. |
