MATCHING NETWORK
The specs of a Fractus Antennas standard product 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 matching
network as close as possible to the feeding point. Do it in the ground plane area, not in the
clearance area. This provides a degree of freedom to tune the ALL mXTEND
TM
chip antenna
component once the design is finished and taking into account all elements of the system
(batteries, displays, covers, etc.).
Please notice that different devices with different ground planes and different components
nearby the ALL mXTEND
TM
chip antenna component may need a different matching network.
To ensure optimal results, the use of high Q and tight tolerance components is highly
recommended (Murata components).

Matching network implemented in the Evaluation Board 1 port (Figure 1).
This matching network applies to this Evaluation Board. Other configurations would require a
matching network adjustment. Please contact
