  • Design aperture coupled patch type MRAAs for mm-wave applications.
  • Co-simulate antenna and RF IC circuit in ANSYS HFSS.
  • Select proper RF materials for mm-wave application based on their electrical and mechanical performance, modeling, and fabrication techniques.
  • Model SMD components (i.e. PIN Diode, Capacitor, inductor and varactor) in Advanced Design System (ADS) from S-parameter data.
  • Work with manufacturing partners to develop customized fabrication and SMD component assembly processes using knowledge of PCB fabrication and component assembly techniques.
  • Design PIN diode control circuit using ADS.
  • Perform PCB layout design and routing in Altium.
  • Prepare PCB fabrication and assembly drawings of MRAAs
  • Design feed networks for MRAAs in ANSYS HFSS.
  • Direct review and definition of complex antenna and electromagnetic test plans and methods and conduct tests and diagnostics using appropriate measurement tools, processes, and procedures, to evaluate design performance, determine material properties.
  • Direct verification and validation efforts to ensure that products meet complex system and sub-tier level electromagnetic design requirements and specifications by reviewing product analysis and test data, manufacturing records, and other relevant information
  • Perform S-parameter measurement of the antenna and RF IC chip in Victor Network Analyzer.
  • Analyze measured and simulated results in MATLAB.
