ARRKP4065-S915A is a UHF RFID antenna designed for wireless identification and tracking in the 902–928 MHz frequency band with a center frequency of 915 MHz. The antenna features a compact 40.0 × 40.0 × 6.5 mm form factor with a dielectric ceramic element (35 × 35 × 4 mm) mounted on an FR4 PCB, delivering a gain of 1.5 dBi and VSWR = 2.0 based on a 40 × 40 mm ground plane. It incorporates right-hand circular polarization (RHCP) with an axial ratio of 3, operates across a bandwidth of 6 MHz at -10 dB, and maintains 50 O impedance with an integrated IPEX RF connector and micro-coaxial cable. The antenna operates reliably from -40°C to +85°C and is RoHS/RoHS II compliant with MSL=1 rating. Ideal for industrial automation, smart cards, asset management, manufacturing, field mobility, and transportation applications where compact, easy-to-install RFID solutions are required.
