1. ANTENNA DESCRIPTION
The Slim Reach XtendTM chip antenna is engineered specifically for wireless headsets using
Bluetooth® and other wireless standards operating at the ISM 2.4 GHz band.
The Slim Reach XtendTM antenna has been designed to resonate at 2.65 GHz in free space
conditions. This has been done purposely because the human head and plastic housing
produce a frequency downshift of 150-250 MHz in the resonance frequency of the antenna.
Based on our research and development in this area, you are not forced to test multiple
antennas with different resonant frequencies.

Other PCB form factors and configurations may require a different feeding configuration, feeding

your design, please contact info@fractusantennas.com.
5. 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).

6. ASSEMBLY PROCESS
Figure 5 shows the back and front view of the Slim Reach XtendTM chip antenna, and indicates
the location of the feeding point and the mounting pads:
Figure 5 – Pads of the Fractus Slim Reach XtendTM chip antenna.
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 7
on page 11.
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 6 – 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.

Mounting Pad (2): solder the antenna mounting pad to the
soldering pad on the PCB. This pad must NOT be grounded.
Feed Pad (1): the white square on the top of the antenna indicates the position of the feed
pad in the bottom. Align the feed point with the feeding line on the PCB. See Figure 1.
