The photonic beamformer was tested with a 2.0 to 4.0 GHz array antenna and pattern results presented. The basic approach can be implemented for larger arrays, but more compact component packaging techniques are recommended. An eight-beam port prototype lens using planar waveguide optical couplers is currently under construction.","PeriodicalId":435637,"journal":{"name":"International Topical Meeting on Microwave Photonics.
