Antenna/Scanner Head for Identification Readers

Product Specifications

Technical details and manufacturing context for Antenna/Scanner Head

Definition

The antenna/scanner head is the critical front-end component of an identification reader that emits electromagnetic signals to interrogate tags or labels and receives their responses. It converts electrical signals into radio waves for transmission and vice versa for reception, enabling wireless data capture from RFID tags, barcodes, or other identification media. This component is designed for integration into readers used in computer, electronic, and optical product manufacturing environments. It typically consists of a copper coil, ferrite core, plastic housing, and PCB substrate, which together form the radiating and receiving structure. The device operates across a frequency range of 860–960 MHz, covering global UHF RFID bands as per ISO/IEC 18000-63, with a gain of 6–9 dBi to enhance read range. Polarization can be linear or circular, with circular reducing orientation sensitivity. The voltage standing wave ratio (VSWR) is ≤1.5 to ensure efficient power transfer, and the impedance is 50 Ω standard. Operating temperature ranges from -20 to 55 °C, while storage temperature spans -40 to 85 °C, with reference to IEC 60068-2-1 and IEC 60068-2-2. Ingress protection is rated IP54–IP65 for dusty or wet environments per IEC 60529. Connector types include TNC or N, with N type offering lower loss at high power, per IEC 60169-1. The weight ranges from 0.5 to 2.0 kg, and dimensions are 200×200×50 to 300×300×80 mm. Power handling is 1–3 W maximum input. These specifications are directory reference ranges; actual values must be confirmed with the legal manufacturer or supplier for the specific model and application. The antenna/scanner head is a component, not a standalone product, and its performance depends on the reader's electronics and environmental conditions.

Working Principle

The antenna/scanner head operates by generating an electromagnetic field when powered, which energizes passive tags or reads active tags. For scanning functions, it may use laser, LED, or imaging technology to capture visual identification data. The received signals are demodulated and processed by the reader's electronics. The antenna's design, including coil and ferrite core, determines its radiation pattern and efficiency. The frequency range and gain affect read distance, while polarization and VSWR influence signal integrity. The component must be matched to the reader's impedance and connector type. Environmental factors such as temperature and ingress protection affect reliability. Proper installation and orientation are critical for optimal performance. The head converts electrical signals to radio waves for transmission and vice versa for reception, enabling wireless data exchange.
