Antenna Testing Sub-system

Testing an antenna array is not a trivial task. It requires assuring the phase and amplitude are properly applied to the antenna elements. An example is illustrated in the Figure 1 where the amplitude values,  to , and the phase values,  to , of the stimulus signals must be accurately determined.

Accurate determination of the amplitude and phase of stimuluses during measurements of an antenna array is difficult to achieve. Errors in the amplitude and phase result in pointing errors and an increase in the sidelobe levels.


At VASBEAM, we developed an antenna testing device (VASATD1) to enable accurate measurements of the antenna array. The device enables calibration of the complex signals applied to each of the antenna element of the array, enabling accurate evaluation of the antenna pattern.
