Key RF Engineering Details That Decide Antenna Long-Term Working Stability

RF parameter consistency directly determines the actual service performance of mass-produced antennas. Raw material dielectric constant deviation and inconsistent PCB copper thickness will lead to impedance drift after batch production, resulting in unstable wireless gain.Ambient temperature change and external electromagnetic clutter also bring hidden troubles to antenna operation. Standardized full-condition RF testing, including high-low temperature aging and near-field interference detection, helps eliminate hidden defects before antennas are assembled into end-use devices.
