Near-field bow-tie antennas for microwave cryogenic applications
Résumé
Printed bow-tie antennas have been designed to operate in X-band in near-field configuration in order to transmit signals over very short distances for cryogenic applications. Transmission between two bow-tie antennas directly placed across from each other has been simulated and measured for different configurations. It is shown that, by placing back-reflecting planes at a proper distance behind each bow-tie antenna, a transmission with losses below 3 dB can be achieved in the 8.0-9.7 GHz range. Detailed experimental results are presented.
