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 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 six components and the following circuit should be designed into the host PCB. Not all components may be required but should be included as a precaution. The matching network must be placed close to the antenna feed to ensure it is more effective in tuning the antenna.

Where this cannot be achieved you should keep as many clear as possible to a minimum of 3. Please note performance will degrade with less clearances. Antennas for Wireless M2M Applications Product Specification DS-SR4L002-PS-1.0 Release date November 2015 Page 13 Lucida Part No. SR4L002 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. Example host layout D = 3.2mm The distance D is the gap required from the antenna SMD pad edge to the ground plane. This should be maintained along the edge the antenna is placed. Antennas for Wireless M2M Applications Product Specification DS-SR4L002-PS-1.0 Release date November 2015 Page 14 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. Lucida Part No. SR4L002 Example host layout Placement of components and GND with traces adjacent to the antenna should maintain a minimum clearance of 15mm from either side. The antenna should be therefore placed in the corner to only have one side effected.

Care must be taken for the placement to ensure that the isolation and cross correlation is within acceptable limits. Below is an example using two Lucida mounted on the same host PCB.

The host PCB ground needs to be as long as the device allows. Reducing the GND directly relates to the performance of the low bands. As shown below you can see the effect of the GND plane length vs the efficiency. 90mm 110mm 130mm Passive Efficiency vs. PCB length All results measured in Antenovas anechoic chamber 130mm 110mm 90mm 90 80 70 60 50 40 30 20 10 0 Antennas for Wireless M2M Applications Product Specification DS-SR4L002-PS-1.0 Release date November 2015 Page 17 Lucida Part No. SR4L002 14.0 Reference Board The reference board has been designed for evaluation purposes of SR4L002 includes a SMA female connector.

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 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 M2Ms website. 17. Packaging 17.1 Optimal Storage Conditions Temperature
-10C to 40C Humidity Shelf life Storage place Packaging Less than 75% RH 24 Months Away from corrosive gas and direct sunlight Reels should be stored in unopened sealed manufacturers 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.
