Comparison of RF photonics-based beamformers for super-wide bandwidth phased array antennas

We demonstrate the NI AWRDE E-CAD tool-based simulation experiments to compare the three arrangements of photonic beamforming networks. The results confirm clearly the benefits of the proposed arrangement based on combination of multichannel fiber Bragg grating and switched optical delay lines providing super-wide operating bandwidth and the better economical characteristics of microwave-band phased array antennas.
