Vishay Vitramon
Fig. 4 displays the measured radiation patterns of VJ 3505 evaluation board in the YZ plane as defined in Fig. 2. Zero degrees
is defined at the Z axis, stepping clockwise.
FOOTPRINT AND MECHANICAL DIMENSIONS
The antenna footprint and mechanical dimensions are presented in figure 5. 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 3505 assembly
guidelines” section below.
