The phenomenon of beam squinting is one of the challenges for wideband mobile communications systems. Although purely digital arrays could resolve this problem utilizing true-time delays (TTDs), they are too expensive w.r.t. power consumption and hardware complexity. Instead, in this letter, we propose a novel codebook-based hardware efficient beamforming architecture that combines subarrays using phase shifters at radio-frequency (RF) with only a few TTDs realized digitally in baseband. The proposed architecture is capable of counteracting the beam squint induced performance loss more strongly with an increasing number of subarrays. Thus, it can approximate the narrowband assumption with different degrees of accuracy and provides an efficient trade-off between complexity and performance.
