3.2. 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. Doit 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 antennamay needa 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

As a surface mount device (SMD), this antenna is compatible with industry standard soldering
processes. The basic assembly procedure for this antenna is as follows:
1. Apply a solder paste to the pads of the PCB. Place the antenna on the board.
2. Perform a reflow process according to the temperature profile detailed in Table 3, Figure 8 on
page 12.
3. After soldering the antenna to the circuit board, perform a cleaning process to remove any
residual flux. Fractus Antennas recommends conducting a visual inspection after the cleaning
process to verify that all reflux has been removed.
The drawing below shows the soldering details obtained after a correct assembly process:
Figure 7 –Soldering Details.
NOTE(*): Solder paste thickness after the assembly process will depend on the thickness of the
soldering stencil mask. A stencil thickness equal to or larger than 127 microns (5 mils) is
required.
The Micro Reach XtendTM antenna should be assembled following either Sn-Pb or Pb-free
assembly processes. According to the Standard IPC/JEDEC J-STD-020C, the temperature
profile suggested is as follows:
