Abstract: A serially fed front end (FE) network is provided. The serially fed FE network includes a first FE comprising a first FE input/output (IO), a second FE IO, and a first antenna IO coupled to a first antenna element of a plurality of antenna elements. The first FE IO of the first FE is electrically coupled to a particular beamformer (BF) IO of a BF. The serially fed FE network includes a second FE comprising a first FE IO coupled to the second FE IO of the first FE, a second FE IO of the second FE, and a second antenna IO coupled to a second antenna element of the plurality of antenna elements. The BF is communicatively coupled by the serially fed FE network to transmit to and/or receive signals from the first and second antenna elements of the plurality of antenna elements.

Abstract: Systems, methods, and computer-readable media are provided for hybrid beamforming. An example method can include determining a plurality of digital beamforming weights associated with a plurality of digital beamforming paths between digital beamformers and groups of analog beamforming circuits in a phased array antenna, each digital beamforming path being coupled to a group of analog beamforming circuits and each analog beamforming circuit being coupled to a respective set of antenna elements of the phased array antenna, and determining analog beamforming weights associated with the groups of analog beamforming circuits. The analog beamforming weights are estimated to put analog beamforming paths associated with the groups of analog beamforming circuits in a desired phase and gain relationship with each other. The method can include varying, based at least partly on the analog beamforming weights, a signal phase shift across the analog beamforming paths associated with the groups of analog beamforming circuits.
