Satellite navigation antenna,which is frequently used,often takes the form of microstrip.Because of its high sensitivity,its characteristics are easily affected by the outside environment.Whether the work environment of satellite navigation antenna is good or not exerts a direct influence upon its performance.This paper explores the work environment of satellite antenna,namely,factors to influent the function of GNSS (Global Navigation Satellite System) and further studies on the electromagnetic compatibility of GNSS.It is supposed that this paper can be helpful to the design of EMC of the entire aircraft.
