Te Role of Intelligence in Predictive Maintenance of Antenna Arrays

Antenna arrays are the backbone of modern contrications, broadcasting, radar, and satellite systems. These encex structures of multiple radiating elements mutt operate with high reliability. Any failure can lead to network outages, reduced signal quality, or costly emergency refictorir.

Understanding Predictive Maintenance

Predictive applicance (PdM) is a proactive stracy that uses data analysis to detect anomalies and predict equipment failures. Unlike reactive accorde accordance (fix after failure) or preventive e accordance (service at filed intervenls retardless of condition), PdM performances only when data indicatetes an impending issue. For antentna arrays, this means monitoring paraters such as signal integraty, impedance, temperature, and mechanical stress continousluy.
