DESCRIPTION
The VJ 6040 multi-layer ceramic chip antenna is a small
form-factor, high-performance, chip-antenna designed for
TV reception in mobile devices in the UHF band. It allows
mobile TV device manufacturers to design high quality
products that do not bear the penalty of a large external
antenna. Utilizing Vishay's unique materials and
manufacturing technologies, this product complies with the
MBRAI standard while maintaining a small outline.
Focusing on consumer applications, the antenna is
designed to be assembled onto a PC board in the standard
reflow process.
Target customers of the VJ 6040 are mobile phone makers,
portable multimedia device makers, notebook OEMs and
ODMs, and accessory card OEMs and ODMs.
The VJ 6040 is the first of a family of products developed by
Vishay, a world leader in manufacturing of discrete and
passive components.

ISDB-T, CMMB, ATSC, and MediaFLO devices
ANTENNE PERFORMANCE
Peak Gain
The antenna radiation characteristics are influenced by
several factors including ground plane dimensions and
impedance matching network.
The antenna parameters presented hereafter were
measured according to the configuration suggested by the
VJ 6040 evaluation board, utilizing its four channel active
digital tuning circuit. The evaluation board ground plane is
40 mm by 80 mm large.
Fig. 1 shows peak gain over frequency throughout the UHF
band, compared with the MBRAI requirements.
