Experimental demonstration of a 3-bit (8 beams) true-time delay optical beamformed beam-switched antenna in the 40GHz band

To our knowledge, this is the first time that an optically beamformed switched beam antenna performance has been evaluated, including radiation pattern and 155 Mb/s 64-QAM 42.7 GHz data transmission measurements in both uplink and downlink direction. It has been also proved that the E/O and O/E conversion and photonic processing of the information signal do not impose any limitation in terms of the measured signal-to-noise ratio, therefore being transparent from a system point of view. This result demonstrates the feasibility of optically beamformed antennas operating in the 40 GHz band to implement advanced smart functionalities for next generation multimedia applications.
