<h1>RFID Antenna: The Heart of Wireless Identification Systems</h1> <p>An <strong>RFID antenna</strong> is the critical component that enables communication between an RFID reader and a tag. From my experience in designing IoT solutions, the performance of the entire RFID system hinges on the antenna's design and integration. I've always had a knack for understanding electromagnetic fields, which proved invaluable when I had to troubleshoot a warehouse tracking system that failed due to poorly matched antennas. My view is that while tags and readers get most of the attention, the antenna is the unsung hero that dictates read range, reliability, and environmental resilience.</p> <h2>Technical Specifications and Parameters of RFID Antennas</h2> <p>For engineers and integrators, understanding the precise specifications is crucial. Below are detailed technical parameters for a common UHF RFID panel antenna model. *Note: These technical parameters are for reference data; specifics need to contact backend management.*</p> <h3>Model: TIANJUN-TJ-AU908</h3> <h4>Detailed Technical Indicators:</h4> <ul> <li><strong>Frequency Range:</strong> 860 MHz - 960 MHz (Global UHF Band)</li> <li><strong>Gain:</strong> 9 dBi (Typical)</li> <li><strong>Polarization:</strong> Circular (Right-Handed)</li> <li><strong>Beamwidth (3dB):</strong> 65° (Horizontal), 65° (Vertical)</li> <li><strong>VSWR:</strong> ≤ 1.5:1</li> <li><strong>Impedance:</strong> 50 Ω</li> <li><strong>Connector Type:</strong> N-Type Female</li> <li><strong>Dimensions:</strong> 245mm x 245mm x 35mm</li> <li><strong>Ingress Protection (IP) Rating:</strong> IP65</li> <li><strong>Operating Temperature:</strong> -40°C to +80°C</li> <li><strong>Integrated Chip/Encoder Reference:</strong> Supports protocol handling via onboard IC (e.g., Impinj R2000-compatible interface).</li> </ul> <p>This high-gain <strong>RFID antenna</strong> from TIANJUN is designed for long-range portal and choke point applications.
