9.0 Antenna footprint
The recommended host PCB footprint is below. This is shown as it should be placed
on the host PCB.
6 copper pads all 1.0 x 1.0 (mm)
*CAD files of the antenna footprint are available at www.antenova-m2m.com.
10.0 Schematic
The circuit for the antenna and the matching components is below. The RF feed
connection and GND connections are critical to the function of the antenna, and must be
followed as shown. This circuit can be used for the circuit capture of the host PCB.

11. Electrical Interface
11.1 Transmission Line
All transmission lines should be designed to have a characteristic impedance of 50Ω.
• The length of the transmission lines should be kept to a minimum
• Any other parts of the RF system like transceivers, power amplifiers, etc, should also
be designed to have an impedance of 50 Ω
Once the material for the PCB has been chosen (PCB thickness and dielectric constant),
a coplanar transmission line can easily be designed using any of the commercial
software packages for transmission line design. For the chosen PCB thickness, copper
thickness and substrate dielectric constant, the program will calculate the appropriate
transmission line width and gaps on either side of the track so the characteristic
impedance of the co-planar transmission line is 50 Ω.
11.2 Matching Circuit
The antenna requires a matching circuit that must be optimized for each product. The
matching circuit will require up to three components and the following pad layout should
be designed into the device so the correct circuit can be installed.
The Pi matching network must be placed close to the antenna feed to ensure it is
more effective in tuning the antenna.

12.0 Antenna Integration Guide
12.1 Antenna Placement
Whichever the host PCB size used, the antenna should be placed ideally on the host
PCB’s longest edge at the centre.
Where the centre is not a viable option the antenna can be placed offset on the PCB to
within the limits shown below. A minimum of 5mm from either PCB edge should be
observed. Where possible this distance should be greater than 5mm.

12.2 Host PCB Layout
The host PCB must ensure the footprint and clearance meets the antenna
specification. An example of the PCB layout shows the antenna footprint with
clearance.
Pins 3, 4 and 6 (GND) are shown directly connecting to the GND with the shortest
route. The feed (Pin 2) connects to the matching circuit close to the antenna.

12.3 Host PCB Clearance
Below shows the antenna footprint and clearance through all layers on the PCB.
Only the antenna pads and connections to feed and GND are present within this
clearance area. The clearance area required is 7.0 x 5.8 (mm).
Example host layout
The clear-out area is simply defined as the same size as the antenna. No additional
clearance is required.

15. Soldering
This antenna is suitable for lead free soldering.
The reflow profile should be adjusted to suit the device, oven and solder paste, while
observing the following conditions:
The maximum temperature should not exceed 240 ºC
However for lead free soldering, a maximum temperature of 255 ºC for no more
than 20 seconds is permitted.
The antenna should not be exposed to temperatures exceeding 120 ºC more
than 3 times during the soldering process.
16. Hazardous Material Regulation Conformance
The antenna has been tested to conform to RoHS requirements. A certificate of
conformance is available from Antenova M2M’s website.
17. Packaging
17.1 Optimal Storage Conditions
Temperature
-10ºC to 40ºC
Humidity
Less than 75% RH
Shelf life
18 Months
Storage place
Away from corrosive gas and direct sunlight
Packaging
Reels should be stored in unopened sealed
manufacturer’s plastic packaging.
Note: Storage of open reels of antennas is not recommended due to possible oxidization
of pads on antennas. If short term storage is necessary, then it is highly recommended
that the bag containing the antenna reel is re-sealed and stored in like storage conditions
as in above table.
The shelf life of the antenna is 2 years, providing the factory seal on the package has not
been broken
