A New TDU-Based Hierarchical Beamforming Framework to Suppress Grating Lobes and Save Space

This paper introduces a new hierarchical beamforming network (HBFN) design methodology that introduces a new degree of freedom in the time delay unit (TDU) allocation across beamforming layers. By varying the TDU delay range within a single layer instead of using a uniform delay profile, this method...
