Latest Patents
Stephen Ma holds a patent for a "Low cost beam steering planar array antenna." This invention features a planar array antenna designed for use with earth-based subscriber units. It generates receive or transmit communication beams through digital beamforming networks, which provide beam steering in one dimension. In another dimension, the communications beams are synthesized using a waveguide structure that is repeated for each row of the antenna array. The outputs of the waveguides are weighted due to the positioning of coupling slots or coupling probes, which transfer carrier signals to and from each waveguide. The coupling elements are connected to barium strontium titanate (BST) or micro-electromechanical systems (MEMS) switch phase shift elements, controlled by a network. The resulting signals are radiated by the antenna elements to form a communications beam.
