Application
Ultrathin Near-Field PCB UHF Antenna for Space-Efficient RFID Enablement
ZK-ANT2925 is a near-field PCB UHF antenna designed for efficient RFID tracking where a thin profile, broad usable coverage, and integration convenience are required. Built from green PCB material, it provides a 297×250×1 mm structure that can be embedded into equipment surfaces, panels, shelves, or fixtures without adding significant thickness. This form factor supports space-efficient RFID enablement in logistics, inventory management, and asset handling installations that rely on consistent tag response from items labeled with durable RFID Labels.
Wideband Operation and Protocol Compatibility
Operating across 860–930 MHz, ZK-ANT2925 supports ISO18000-6B and ISO18000-6C (EPC C1G2) to match mainstream UHF RFID deployments. Circular polarization improves read stability when tag orientation varies, which is common on shelves, work surfaces, and mixed-item handling stations. During installation validation or periodic audits, RFID Handheld Readers can be used to confirm that the near-field behavior and coverage meet the intended workflow.
Broad Beam Coverage for Practical Indoor Read Zones
The antenna is specified with 4.5 dBi gain and a 0–5 m reading range, supporting practical tracking tasks across controlled indoor read zones. Beamwidth is specified as 93° horizontal and 75° vertical, offering broad coverage that helps reduce the need for frequent mechanical re-alignment. This is especially useful when the antenna is embedded behind a panel or under a surface and the objective is consistent zone coverage rather than pinpoint beam control. For specialty items that require gentle handling and reliable identification—such as Wooden Cards—the broad field can support smoother workflows by reducing positioning sensitivity.
Electrical Matching, Power Handling, and Protection
For stable integration, ZK-ANT2925 is designed around 50 Ω impedance with VSWR ≤ 2 and supports up to 50 W maximum input power. It connects via an SMA interface, and connector solutions can be adapted to installation needs. It also provides direct-ground lightning protection to support safer deployment in practical electrical environments. Working temperature is -40 to 70°C. In compact embedded systems, it can also be implemented alongside UHF RFID Integrated Readers to streamline the reader-and-antenna layout while keeping installation thin and space-efficient.
Designed for Simple Embedding and Repeatable Operations
By combining an ultrathin PCB structure, circular polarization, broad beam coverage, and stable electrical matching, ZK-ANT2925 supports efficient RFID tracking and inventory operations while keeping installation simple and space-efficient in real deployments.
