Latest Patents

Chak-Ming Chie's latest patents include "Hierarchically Elaborated Phased-Array Antenna Modules and Faster Beam Steering Method of Operation." This system updates all phase shifter values of a phased array antenna using two 'global writes' to simultaneously update parameters across all phased-array transformation circuits via a serial bus. Each antenna element is controlled by a phased-array transformation circuit, which is configured to transform phase and gain according to a register array. The register array consists of a local register group and a central register group, with local registers placed close to RF chains corresponding to each antenna element. This configuration allows for individual control of antenna elements and overall beam steering functions. The apparatus efficiently elaborates phase shift weights into a submodule of a phased array antenna system, ensuring low noise and bandwidth.
