ARRSN5-915.000MHZ is a passive RFID reader antenna designed for 915 MHz operation with a compact 50.0 x 50.0 x 9.4 mm form factor. The antenna features a center frequency of 915±3 MHz with a 5.0 MHz bandwidth (at V.S.W.R < 1.5), 2.5 dBi gain based on a 70×70 mm ground plane, and right-hand circular polarization (RHCP) for optimal signal reception. It incorporates a dielectric ceramic antenna element (45×45×6 mm) mounted on an FR4 PCB with an RG178 RF cable (F 2.7±0.3 mm) and MMCX-J3 connector, operating reliably across -40°C to +80°C. This antenna is ideal for RFID systems in retail, pharmaceutical, and automotive logistics, as well as industrial automation and contactless smart card applications, offering high gain performance with easy installation and RoHS compliance.
