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.

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.

Applications that do not require full coverage of the UHF band can gain an additional two to three dBi by removing the tuning
circuit. In this case the antenna can be fixed to any 150 MHz band within the UHF range.

FOOTPRINT AND MECHANICAL DIMENSIONS
The antenna footprint and mechanical dimensions are presented in Fig. 6. For mechanical support, it is recommended to add
one or two drops of heat curing epoxy glue. The glue dot should not overlap with any of the soldering pads. It is recommended
to apply the glue dot at the center of the antenna, as shown by the diagonal pattern. For more details see “VJ 6040 Assembly

VJ 6040 ASSEMBLY GUIDELINES
1. Mounting of antennas on a printed circuit board should be done by reflow soldering. The reflow soldering profiles are shown
below.
2. In order to provide the adequate strength between the antenna and the PCB the application of a dot of heat cured epoxy
glue in the center of the footprint of the antenna prior to the antenna’s soldering to the board should be done. An example
for such glue could be Heraeus PD 860002 SA. The weight of the dot should be 5 mg to 10 mg.
