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 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 Micro Reach Xtend
™ chip antenna may need a different matching network. To ensure optimal
results, the use of high Q and tight tolerance components is highly recommended (Murata
components). If you need assistance to design your matching network beyond this application
