MATCHING NETWORK
The specs of a Fractus Antennas standard antenna are measured in their evaluation board,
which is an ideal case. In a real design, components nearby the antenna, LCD’s, batteries,
covers, connectors, etc. affect the antenna performance. This is the reason why it is highly
recommended placing pads compatible with 0402 and 0603 SMD components for a PI matching
network as close as possible to the antenna feeding point. Do it in the ground plane area, not in
the clearance area. This is a degree of freedom to tune the antenna once the design is finished
and considering all elements of the system (batteries, displays, covers, etc.).
