Optical Multi-beam Formation Technology of Broadband Phased Array Antenna Based on Stack Integrated Micro-optical Components
A transceiver integrated optically controlled phase array antenna system was introduced. The true time delay of the system was generated by stack integration of micro-optical components. The antenna system accomplishes the control of microwave signal by virtue of controlling the time delay in optical domain. Experimental verification of the system in receive mode is conducted. Experimental results on steering angle of ±10.6°、±30.8°demonstrate that maximum error of steering angle at ±10.6°is 3.1°and that at ±30.8°is 1.2°under 2-6 GHz broadband microwave signal. The dynamic range of the optically controlled phase array antenna at 2 GHz microwave frequency is about 71 dB. The system can realize radio frequency independent broadband beam steering and the tracking of moving target in azimuth angle direction in one-dimensional plane.
