The 2 dBi Circular Polarized UHF RFID Ceramic Antenna is a compact antenna designed for UHF RFID applications operating at 915 MHz and 866.5 MHz. Its circular polarization helps maintain reliable tag communication when RFID tags are positioned at different angles, making it suitable for applications where tag orientation may vary.
With an overall antenna size of just 28 × 28 mm and a compact 18 × 18 × 4 mm ceramic antenna element, this design is well suited for RFID readers, embedded RFID devices, smart equipment, access control systems, asset tracking devices, and other space-constrained applications.
The antenna provides a gain of 2 dBi ±1 dBi, a 50 Ω impedance, and an axial ratio of ≤5 dB. PCB and ceramic construction offers a compact and practical solution for integrating UHF RFID functionality into electronic equipment.
Various terminal options and SMA connectors are available to support different installation and connection requirements. With an operating temperature range of -25°C to 75°C, the antenna can be used in a wide range of indoor and commercial RFID environments.
