Abstract :
To measure the S-parameters of patch antennas fed by microstrip with vector network analyzer (VNA), a test fixture based on Coplanar Waveguide Ground (CPWG) is designed. Single-port OSL calibration method is used to calibrate the test system to eliminate the directional errors, frequency response errors, source match errors. Finally calculate the actual S-parameters of microstrip antenna.
