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 coplanar transmission line is 50Ω. 10-2 Matching circuit The antenna requires a matching circuit that must be optimized for each customer’s 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 antenna feed pad and the antenna ground pads are indicated in the drawing above. Additional pads are for mechanical attachment only and should not be grounded. Antennas for Wireless M2M Applications 7 Product Specification 09MD-0019-3-PS Brevis GPS SMD Antenna Part No. A10204 In addition to the matching circuit, a separate DC blocking capacitor will also be required between the radio and the antenna matching circuit. Note: The component values for the matching circuit will vary depending on the size of the PCB and surrounding components. The impedance of the antenna should be measured before selecting suitable matching components. Antenova M2M offers this service on request. Contact sales@antenova-m2m.com for further information. 10-3 Antenna placement Antenna placement locations and orientations are critical for achieving optimal system performance. Antenova strongly recommends placing the antenna near the edge of the board. Maximum antenna performance is achieved by placing the antenna towards one of the corners of the PCB, with the feed point of the antenna as close to the corner of the PCB as possible. Antenova M2M offers a full range of development support to ensure efficient implementation of the antenna into the specific design. To overcome RF design issues, matching circuits, transmission lines, layout and other components, please contact Antenova M2M (sales@antenova-m2m.com) for design and placement recommendations. 10-4 Reference board The reference board has been designed for evaluation purposes of the Brevis A10204 antenna and it includes a SMA female connector Dimensions in mm Contact sales@antenova-m2m.com for further details Antennas for Wireless M2M Applications 8 Product Specification 09MD-0019-3-PS Brevis GPS SMD Antenna Part No. A10204 11 Soldering This antenna is suitable for lead free soldering. The reflow profile should be adjusted to suit the PCBA, 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. 12 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. 13 Packaging 13-1 Optimal storage conditions for packaged reels 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.
