The antenna uses a matching circuit to achieve optimized results for the specific frequency bands that are required. This product specification shows the performance of the antenna when optimized to cover a typical penta-band reception: GSM850/900/1800/1900 and WCDMA. 3 Applications • • • • • Mobile handsets Femto / Pico base stations Tracker devices Machine to machine communication Remote monitoring Antennas for Wireless M2M Applications 1 Product Specification 12MD-0047-3-PS Rubra GSM SMD Antenna Part No. A10393 4 Part number Rubra: A10393 5 General data Product Name Rubra GSM SMD Part Number A10393 Frequency 824 – 960 MHz 1710 – 2170 MHz Polarization Linear Operating Temperature -40 ºC to +85 ºC Impedance with Matching 50 Ω Weight 2.5 g Antenna Type SMD Dimensions 40 x 10.4 x 3.2 [mm] Material Halogen-free FR4 6 Electrical characteristics Typical performance Peak gain Conditions 1.8dBi @ 830 MHz 3.8dBi @ 1980 MHz -1.2dBi 824-960 MHz Average gain (Linear) -1.8dBi 1710-2170 MHz Average efficiency 824-960 MHz 1710-217 MHz 75% 65% Maximum Return Loss -6 dB Maximum VSWR 2.6:1 All data measured on Antenova’s reference board, part number A10393-U1 Data given for the 824MHz-960MHz and 1710MHz-2170MHz frequency ranges Antennas for Wireless M2M Applications 2 Product Specification 12MD-0047-4-PS Rubra GSM SMD Antenna Part No. A10393 7 Electrical performance 7-1 Return Loss 7-2 VSWR Antennas for Wireless M2M Applications 3 Product Specification 12MD-0047-4-PS Rubra GSM SMD Antenna Part No. A10393 7-3 Antenna patterns 824-960 MHz Z Y X XY plane YZ plane XZ plane Patterns show combined polarisations measured on reference board A10393-U1. 3D Pattern measured at 890MHz Antennas for Wireless M2M Applications 4 Product Specification 12MD-0047-4-PS Rubra GSM SMD Antenna Part No. A10393 7-4 Antenna patterns 1710 – 2170 MHz Z X XY plane YZ plane Y XZ plane Patterns show combined polarisations measured on reference board A10393-U1. 3D Pattern measured at 1894MHz Antennas for Wireless M2M Applications 5 Product Specification 12MD-0047-4-PS Rubra GSM SMD Antenna Part No. A10393 8 Antenna efficiency 100 Free Space Terminal Efficiency [%] 90 80 Average 73% Average 72% Average 78% 70 Average 64% Average 72% 60 50 40 30 20 10 0 Frequency [MHz] 820 880 890 960 1710 1850 1880 1920 GSM900 2170 UMTS2100 DCS1800 GSM850 1990 PCS1900 Antennas for Wireless M2M Applications 6 Product Specification 12MD-0047-4-PS Rubra GSM SMD Antenna Part No. A10393 9 Antenna dimensions L W H Length Width Height 40.0 +/- 0.2 10.4 +/-0.2 3.2 +/- 0.15 A B C D E F G H I J K L M 1.0 +/0.15 1.5 +/0.15 0.2+/0.15 0.9 +/0.15 2.6 +/0.15 8.15+/0.15 5.49 +/0.15 8.76 +/0.15 38.10 +/- 0.15 9.0 +/0.15 10.91 +/- 0.15 17.72 +/- 0.15 9.47 +/0.15 Dimensions in mm Antennas for Wireless M2M Applications 7 Product Specification 12MD-0047-4-PS Rubra GSM SMD Antenna Part No. A10393 10 Antenna footprint Rubra GSM (Part No: A10393) CAD files of the antenna footprint are available to download from www.antenova-m2m.com.

Antennas for Wireless M2M Applications 9 Product Specification 12MD-0047-4-PS Rubra GSM SMD Antenna Part No. A10393 11 Electrical interface 11-1 Transmission lines The antenna should be connected using an RF transmission line. All transmission lines should be designed to have a characteristic impedance of 50 Ω 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 Ω Once the material for the PCB has been chosen (PCB thickness and dielectric constant), a co-planar 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 Ω. Antennas for Wireless M2M Applications 10 Product Specification 12MD-0047-4-PS Rubra GSM SMD Antenna Part No. A10393 11-2 Matching circuit The A10393 antenna requires an impedance matching circuit that must be optimized for each customer’s product. The matching circuit will typically require 3 matching components, and up to five components depending on the impedance of the antenna when situated in the device. It is recommended that all the components in the reference schematic (Figure 1) are included in the layout. Moreover, the antenna requires an additional inductor L1 on the return pin, which is used to adjust the resonant frequency in the low band (see below). Important: The position of the antenna feed and return pads are fixed for this product and the positions cannot be swapped over. Please check the reference layout for the relative position.

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 offers a matching service on request. Contact info@antenova.com for further information Antenna frequency adjustment The resonant frequency of the antenna can be adjusted to compensate small detuning caused by nearby objects like a plastic case or a large metal component. The adjustment mostly affects the low-band resonance [824-960MHz], with a lesser effect on the upper frequency band [1710-2170Hz]. The adjustment in the resonant frequency is achieved by changing the value of the L1 component on the grounding connection of the antenna: • Default L1 component is a 0Ω jumper (R0) • If an inductor is used as L1, the low-band resonant frequency reduces as the value of the inductor increases, as shown on the right hand side of Figure 2. • If a capacitor is used as L1, the low-band resonant frequency increases as the value of the capacitor is reduced, as shown on the left hand side of Figure 2. Figure 2 graphically shows the relation between the type and value of the L1 component and the variation in the low-band resonant frequency. Notice that the scale of the component’s values is not linear.

Antennas for Wireless M2M Applications 13 Product Specification 12MD-0047-4-PS Rubra GSM SMD Antenna Part No. A10393 11-3 Antenna placement Rubra should be fitted to the device so that power from the antenna can radiate into free space. Antenova strongly recommends placing the antenna near the edge of the board. Maximum antenna performance is achieved by placing the antenna close to the corner of the PCB with few components or metal objects nearby. The antenna requires a ground free area below the antenna on all PCB layers. Ground can be placed at the side of the antenna with a clearance of >10mm from each side recommended, including free from components or conducting objects. The placements shown here are for guidance only, as the actual performance differences will depend on each individual device. 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.

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. • • 13 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. 14 Packaging 14-1 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.
