A 60 GHz volumetrically scanning array employing a switched beam network is presented. Unlike existing switched beam networks operating at this band, the proposed network realizes volumetric scanning without using multiple switching stages. The network operates in the entire unlicensed 60 GHz band (57-64 GHz) via an innovative delay structure to compensate for the phase shift caused by the planar RF crossovers employed in the network. In this paper, we describe the beamforming network and accompanying aperture-coupled patch array. Relevant simulation results are presented to demonstrate the RF front-end operation. ©2010 IEEE.
