Abstract
A wireless coupling method is suitable for use in calibration and testing of a radiofrequency device under test (DUT). The DUT includes a printed circuit board having one or more integral antennas. The wireless coupling method comprises the use of a test fixture to position the DUT a prescribed distance from a reference unit comprising a second printed circuit board with one or more similar integral antenna(s). Each antenna of the reference unit is aligned optimally to a corresponding antenna of the DUT for transmitting or receiving RF signals in one or more frequency channels in accordance with a test procedure script. Test equipment is coupled to the antennas and is used for measuring or generating each test of the test procedure and saving the measurements in memory.
