Designed for reliable RFID and wireless communication applications, this 5 dBi circularly polarized ceramic antenna combines a compact ceramic element with a PCB structure to provide stable RF performance in a space-efficient design.
Operating at 915 MHz or 866.5 MHz, the antenna offers a gain of 5 dBi ± 1 dBi and a 50 Ω impedance, making it suitable for integration with compatible RFID readers and RF equipment.
Compact Ceramic Antenna Design
The ceramic antenna element measures 40 × 40 × 5 mm, while the overall antenna size is approximately 60 × 60 mm. Its compact form factor makes it suitable for equipment where installation space is limited.
The antenna uses a PCB + ceramic construction, combining the advantages of a ceramic antenna element with a practical PCB-based structure.
Circular Polarization for Flexible Tag Reading
With circular polarization and an axial ratio of ≤5 dB, this antenna is designed to support stable RF communication when the orientation of RFID tags or wireless devices varies.
This makes it a practical choice for RFID applications where tags may not always maintain a fixed orientation relative to the reader antenna.
Flexible Connector Options
The antenna can be configured with SMA connectors or various terminal types, providing flexibility for different RFID reader designs, wireless devices, and installation requirements.
Reliable Operating Temperature Range
The antenna supports an operating temperature range of -25°C to 75°C, allowing it to be used across a variety of indoor, commercial, and industrial environments.
