Grandis Antenna for ISM applications Part No. SR42I010-L & SR42I010-R 1. lamiiANT (R) Product Specification Features 2. Antenna for ISM 868 and 915 MHz applications including LoRa, SigFox, and Weightless-P Frequency bands from 863 - 928MHz Maintains high performance on device: DFI (Designed for Integration) Corner placement to save space Low profile innovative design SMD mounting Supplied in Tape and Reel Automotive temperature rating Description The Grandis antenna uses a ground plane on the host PCB to radiate effectively. The antenna itself requires a clearance underneath. An external matching circuit is used to optimise the antenna within a device to the required bands. Designed specifically for 868/915 ISM applications that require a small robust solution. Grandis comes in Left and Right hand versions to optimise placement on a host PCB. 3.

Schematic Symbol and Pin definition The circuit symbol for the antenna is shown below. The antenna has 9 pins with only two as functional. All other pins are for mechanical strength. Pin Description 2 Feed 1 Band Select (B.SEL) 3,4,5,6,7 Not used (Mechanical only) 10.0 Antenna footprint The recommended host PCB footprint is below. 7 copper pads all 1.8 x 1.3 (mm) All Dimensions in mm Antennas for Wireless M2M Applications Product Specification SR42I010-PS-1.0 Page 7 Grandis Part No. SR42I010 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 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 five 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. Antennas for Wireless M2M Applications Product Specification SR42I010-PS-1.0 Page 8 Grandis Part No. SR42I010 12.0 Antenna Integration Guide 12.1 Antenna Placement Whatever the size of the host PCB, the antenna should ideally be placed on the host PCB's shortest side, in the corner. The antenna should be placed in the corresponding corner: SR42I010-L (Left corner) and SR42I010-R (Right Corner). 12.2 Host PCB Layout The design for the host PCB must ensure that the footprint and clearance meets the antenna specification. An example of the PCB layout shows the antenna footprint with clearance. The feed (Pin 2) connects to the matching circuit close to the antenna. For Pin 1 (B.SEL) the component should be close to this pin. Example host layout 1 Antennas for Wireless M2M Applications Product Specification SR42I010-PS-1.0 Page 9 Grandis Part No. SR42I010 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 12.0 x 11.0 (mm). The clear-out area is simply defined as the same size as the antenna. No additional clearance is required.

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. 15. 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. 16. Packaging 17.1 Optimal Storage Conditions Temperature -10C to 40C Humidity Less than 75% RH Shelf life 24 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.
