  • KA-BAND 2D PHASED-ARRAY ANTENNA IN PACKAGE
    Publication number: 20230378642
    Abstract: A phased antenna array in a package is provided. The phased array antenna in a package comprises an antenna array with an integrated passive beamformer network, and at least one actuation mechanism. The passive beamformer network comprises at least one phase shifter, and each of the at least one phase shifter comprises a transmission line having a slow-wave structure and a ceramic. Each of the at least one actuation mechanism comprises a magnet and an electromagnet coil, where the magnet is coupled to the ceramic. The at least one actuation mechanism configured to increase or decrease a gap between the transmission line and the ceramic.

  • Planar MEMS-based phase shifter having a MEMS actuator for adjusting a distance to provide a phase shift
    Patent number: 11495869
    Abstract: A planar micro-electromechanical system (MEMS)-based phase shifter is described which comprises a dielectric substrate, a grounded coplanar waveguide (GCPW) transmission line for carrying input and output signals, a high-resistivity silicon (HRS) slab coated with metallic gratings over the GCPW line, and a MEMS actuator for adjusting a distance between the HRS slab and the GCPW line to provide a phase shift.
