Integrated photonic antenna array

Photonic beam forming networks benefit from the broad bandwidth and low attenuation of optical waveguides. The performance of this approach is maximized by placing the opto-electrical conversion (photodiode) directly at the feeding point of the antenna. In this work, such a setup that combines the optical true time delay (TTD) technique and photonic feeding is designed and demonstrated with a four element array of Vivaldi antennas working in the broad frequency range from 0.5- 2.5 GHz. Measurements are presented and discussed.
