Abstract :
A new type of digital beamforming (DBF) multibeam antenna array is proposed. In this antenna array, the amplitude and phase distributions on the array aperture are recovered using a single radio frequency (RF) channel through time sequence phase weighting (TSPW). The distributions can then be used to produce multibeams by digital beamforming. A proof-of-concept prototype of an eight-element receiving array in JC-band has been fabricated and tested. The measured results confirm the validity and advantages of the proposed scheme.
