J. Marti et al., Millimetre-wave optical beamforming network for phased-array antennas employing optical upconversion and wideband chirped fibre gratings, ELECTR LETT, 35(7), 1999, pp. 517-518
A novel optical beamforming architecture for phased-array antenaas operatin
g at millimetre-wave frequencies is presented. Experimental results at 28 G
Hz have demonstrated the very good performance of this technique, based on
optical upconversion and wideband chirped fibre gratings.
