Summary:
|
AAS known as active antenna system is widely spread within communication systems and vertical industries with its benefit of higher beam-forming gain which can overcome the high path loss of higher carrier frequency. For the introduction of AAS especially the integrated antenna array, corresponding electromagnetic compatibility test configuration and measurement methods should be paid to special attention. Radiated immunity as an example will increase dramatically as the antenna array gain cannot be distinguished. Other technical issues such as radiated immunity test, communication link establishment, performance assessment, EMF exposure problem for test personnel, etc. are also proposed.
