Other patents are pending.
DESCRIPTION
The VJ5301M915MXBSR ceramic chip antenna is a small
form-factor, high-performance, chip-antenna designed for
operation at 915 MHz. It allows manufacturers to design
high quality products that do not bear the penalty of a large
external antenna, and is designed to be assembled onto a
PC board using a standard reflow process.
The VJ5301M915 is the latest in a family of products
developed by Vishay, a world leader in manufacturing of
discrete and passive components.
The     VJ5301M915     series     are     small     form-factor,
high-performance chip-antennas optimized for medical,
remote sensing, industrial, security, and RFID applications.
Utilizing   unique   Vishay   materials   and   manufacturing
technologies, these products when properly tuned also
comply    with    the    MBRAI    standard    for    portable
communication.

Note
(1)
See figures 1 through 6 for more details on the radiation pattern
(antenna gain) at 915 MHz; the PCB board ground is shorted to
earth ground for tuning.
APPLICATIONS
" Medical telemetry (internal/external)
" Remote sensing and control
" Industrial automation and telemetry
" Security systems, home automation
" Long range RFID
