See figures 1 through 6 for more details on the radiation pattern (antenna gain) at 868 MHz the PCB board ground is shorted to earth ground for tuning. DESCRIPTION The VJ5301M868MXBSR ceramic chip antenna is a small APPLICATIONS form-factor, high-performance, chip-antenna designed for Medical telemetry (internal/external) operation at 868 MHz. It allows manufacturers to design Remote sensing and control high quality products that do not bear the penalty of a large external antenna, and is designed to be assembled onto a Industrial automation and telemetry PC board using a standard reflow process. Security systems, home automation The VJ5301M868 is the latest in a family of products Long range RFID developed by Vishay, a world leader in manufacturing of discrete and passive components. ELECTRICAL SPECIFICATIONS The VJ5301M868 series are small form-factor, Operating temperature: -40 C to +85 C high-performance chip-antennas optimized for medical, Frequency range (transmission/reception): remote sensing, industrial, security, and RFID applications. 820 MHz to 920 MHz Utilizing unique Vishay materials and manufacturing Note technologies, these products when properly tuned also Electrical characteristics at +25 C unless otherwise specified. comply with the MBRAI standard for portable Antenna performance is measured at 868 MHz and 50 impedance unless otherwise specified. The best results are communication. obtained by mounting the chip following the layout guidelines application note for the evaluation kit. QUICK REFERENCE DATA FREQUENCY MAX.
