Polymer-Based Photonic Phased-Array Antenna System Based on Detector-Switched Optical Blass Matrix True-Time Delay Steering
Abstract
This paper reports progress on the substrate guided wave optical true-time delay technique for photonic phase array antenna. Presented is a new optical TTD module design, and the work for PAA system demo. Like other photonic PAA technique, our structure can provide ultra-wide instantaneous bandwidth for PAA, without beam squint, which means when you change microwave frequency, the steering angle will not change. In addition, the optical beamforming network will have very high package density (2.5 delay lines/cmA2) and low weight. It will be more reliable and be able to avoid the electromagnetic pulse attack. Can easily work at high RF frequency, especially at millimeter wave, which is very difficult for electrical method, because no practical microwave transmission line exists. Photonic PAA can let us put all the signal processing unit in some control center, and transfer the signal to remote antenna head through fiber optic link.
