1. ANTENNA DESCRIPTION
The Compact Dual-band Reach XtendTM chip antenna is engineered specifically for high
performance dual-band WLAN devices operating at both 2.4 – 2.5 GHz and 4.9 – 5.875 GHz
and using 802.11 ac/a/b/g/n systems. Compact Dual-band Reach XtendTM combines small size
with high performance to improve the functionality of your wireless devices. Its small dimensions
allow various configurations within the USB devices and may help Card-bus devices in the
enhancement of their throughput by using MIMO algorithms with more than 2 antennas.
The Compact Dual-band Reach XtendTM chip antenna uses space-filling properties of Fractus
Antennas technology to minimize its size while maintaining a high radiation efficiency value.
This directly impacts antenna reliability in achieving a greater communication range (distance)
and in improving battery life. Compact Dual-band Reach XtendTM features an omnidirectional
radiation pattern optimal for highly scattered environments such as indoor environments and
public spaces. Moreover, its broad bandwidth gives you design flexibility to create robust
designs that operate at all global WLAN standards.

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 Compact Dual-band Reach XtendTM chip antenna,
and indicates the location of the feeding point and the mounting pads:
Figure 5 – Pads of the Fractus Compact Dual-band 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.

Feed Pad (1): the black 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.
