提出了一种新型的无线电磁信号识别装置，该装置采用电光调制器和嵌入正交隙的平面贴片天线阵列。无线电磁信号可以被检测到，并通过光调制直接转换成光波信号。可以精确地测量和识别无线信号的幅度、相位和极化。通过使用弯曲间隙结构，可以更精确地调谐无线信号转换的方向性。此外，还可以通过比较来自两个正交光波导的两个正交调制光信号来获得无线信号在二维空间中转换的方向性。给出了该器件的设计、分析和在26 GHz工作频率下的实验结果。
We proposed a new wireless electromagnetic signal discrimination device using electro-optic modulators and an array of planar patch antennas embedded with orthogonal gaps. Wireless electromagnetic signals can be detected and converted directly to lightwave signals through optical modulation. The magnitude, phase, and polarization of the wireless signal can be measured precisely and identified. By using meandering gap structures, the directivity of the wireless signal conversion can be tuned more precisely. Furthermore, the directivity of the wireless signal conversion in two-dimensional space can also be obtained by comparing two orthogonal modulated lightwave signals from two orthogonal optical waveguides. The design and analysis of the device and experiments at an operational frequency of 26 GHz are presented.
