10-3 Antenna placement
Flavus must be fitted to the device so that power from the antenna can radiate into free space.
Antenova recommends fitting the antenna close to the corner of the PCB with few components
or metal objects nearby. Ground can be placed at the side of the antenna closest to the feed,
but the remaining space around the antenna, including directly above and below should be free
from components or conducting objects.
Two recommended configurations are shown below, but other layouts are possible.
10-4 Space saving configuration
Integrated Antenna and RF Solutions
Where board space is limited, Flavus can be positioned closer to the main PCB ground plane
as shown below. In this position good results can be achieved in up to three bands as shown
in the performance table.
Please contact info@antenova for technical advice on getting the best results from Flavus into
your product.
Recommended PCB layouts: antenna mounted straight (left) and at 45 degrees (right).
