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
