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. Pi Network Antennas for Wireless M2M Applications Product Specification Antennas for Wireless M2M Applications Page 6 Sinica Part No. SR4G008 11. Electrical Interface 11.1 Transmission Line All transmission lines should be designed to have a characteristic impedance of 50. * 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 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 . 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.

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. >5mm >5mm Antennas for Wireless M2M Applications Product Specification Antennas for Wireless M2M Applications Page 8 Sinica Part No. SR4G008 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. Example host layout Antennas for Wireless M2M Applications Product Specification Antennas for Wireless M2M Applications Page 9 Sinica Part No. SR4G008 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. 7.0mm 5.8mm Clearance area Antennas for Wireless M2M Applications Product Specification Antennas for Wireless M2M Applications Page 10 Sinica Part No. SR4G008 13.0 Host PCB Size The minimum recommended host PCB size to be used is 40 x 20 (mm).

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 C However for lead free soldering, a maximum temperature of 255 C for no more than 20 seconds is permitted. The antenna should not be exposed to temperatures exceeding 120 C 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 -10C to 40C Humidity Less than 75% RH Shelf life 18 Months Storage place Away from corrosive gas and direct sunlight Reels should be stored in unopened sealed manufacturer's plastic packaging. 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 Antennas for Wireless M2M Applications Product Specification Antennas for Wireless M2M Applications Page 13 Sinica Part No. SR4G008 17.2 Tape Characteristics Do 1.55 +0.1 Ao 6.10 0.1 E 1.75 0.1 Bo 7.30 0.1 F 7.50 0.1 P0 4.00 0.1 W 16.00 0.3 P1 12.00 0.1 P2 2.00 0.1 K0 0.95 0.1 Dimensions in mm Notes: a) Sprocket hole pitch cumulative tolerance = 0.2 b) Chamber not to exceed 1mm in 100mm c) Ao and Bo measured on a plane 0.1mm above the bottom of the pocket. d) K0 measured from a plane on the inside bottom of the pocket to the top surface of the carrier.
