Electrical Interface 9.1 Host Interface The host PCB requires the mating connector which is IPEX MHF (UFL) receptacle. The location should be close to the chip/modules pin for the RF. Any feed from this receptacle should be maintained at 50 impedance. 9.2 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 feed. A DC blocking capacitor should be placed in line to protect the RF front end. 10. Mechanical Fixing The antenna uses 3M 468MP adhesive on the reverse side of the FPC. The antenna has an easy access split line to peel off to reveal the adhesive side. It is designed for a one time fix to a clean smooth surface. FPC back side Split line for easy peel Antennas for Wireless M2M Applications Product Specification SRF2W012-PS.1.2 Page 8 Dromus Part No. SRF2W012 10.0 Antenna Integration Guide 10.1 Placement For placing the FPC antenna within a device, the host PCB size is not a factor like PCB mounted antennas. However placement still needs to follow some basic rules, as any antenna is sensitive to its environment. Using six spatial directions shown below as a guide. The antenna FPC section should try to maintain a minimum of three directions free from obstructions to be able to operate effectively. The other directions will have obstacles in its path, these directions still require a minimum clearance. These minimum clearances are further defined in this section. The plastic case is not included in this, only metal objects/components that will obstruct or come in close proximity to the antenna. Six spatial directions relative to FPC Example with 4 spatial directions clear Battery FPC PCB Antennas for Wireless M2M Applications Product Specification SRF2W012-PS.1.2 Page 9 Dromus Part No. SRF2W012 10.2 Orientation of FPC The orientation of the FPC with respect to the host PCB should be defined depending on the unit. The proximity of the GND will have an influence on the antenna so the PCB location relative to the antenna should be considered. The FPC will normally be placed in one of the three following options for orientation. In each option a distance (d) is the critical dimension to consider. Below shows the minimum value of (d) for each. Other obstructions may increase this dimension. 1) Vertical mounted FPC Cable +Connector PCB d 2mm 1) Co-planar to PCB d 10mm 2) Planar to PCB (Same plane) d 2mm Antennas for Wireless M2M Applications Product Specification SRF2W012-PS.1.2 Page 10 Dromus Part No. SRF2W012 10.3 Device Integration example An example of integration within a device is shown below. The device contains the major components along with the device outer case. The FPC is shown adhered to the inside of the device's plastic housing. The cable routing is along the edge of the PCB so as not to interfere with any other component. The length of the cable is sufficient to allow ease of assembly when produced (SRF2W012-100). The FPC was placed vertically relative to the PCB. The battery is conductive and is kept the minimum recommended distance away from the FPC of 10mm. The FPC is kept at maximised height above the PCB to ensure it is above the minimum clearance of 2mm. This example shows the FPC 5mm above the PCB. For vertical placement relative to PCB d=5mm (min 2mm) Distance to battery follows minimum spec for co-planar placement d= 10mm (min 10mm) Antennas for Wireless M2M Applications Product Specification SRF2W012-PS.1.2 Page 11 Dromus Part No. SRF2W012 11. 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. 12. Packaging The antennas are stored in individual plastic (PE) bags, then stored within a second bag of 10pcs. Single antenna per bag 10 units per second bag (Labelled) 12.1 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 Antennas should be stored in unopened sealed manufacturer's plastic packaging. Packaging The shelf life of the antenna is 18 months, provided the bag of 10 pieces remains factory- sealed.
