A K-band phased array antenna system employing photonic true-time delay module
نویسندگان
چکیده
A novel 1-to-64 (6-bit (2 6 )) optical true-time delay module that can provide linear time delays ranging from 0 to 443.03 picoseconds is presented. The bandwidth of the fully packaged module is determined to be as high as 539 GHz. This true-time delay module is employed to control an eight-element K-band phased array antenna system. Far field patterns covering 18 GHz to 26.5 GHz are measured and compared with the simulated results to verify this module’s wide instantaneous bandwidth. This module can be employed to control phased array antennas working at 5 GHz – 40 GHz.

We report dual RF beam reception of an X band phased array antenna using a photonic crystal fiber (PCF)-based delay network. Each incoming RF signal can be independently received, and the angle of arrival can be determined based on the delay time-dependent wavelength. Two RF signals with frequencies 8.4 and 12 GHz impinge upon an X-band antenna array from -7.4 degrees and -21.2 degrees . These ...
