Electrical Interface 11.1 Transmission Line All transmission lines should be designed to have a characteristic impedance of 50Ω. • 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 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 Ω. 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.

Where the centre is not a viable option, the antenna can be placed offset on the PCB to within the limits shown below. A minimum of 6mm from either PCB edge should be observed. Where possible this distance should be greater than 6mm.

An example of the PCB layout, below, shows the antenna footprint with clearance. Pins 3, 4 and 6 (GND) are shown directly connecting to the GND with the shortest route. The feed (Pin 2) connects to the matching circuit close to the antenna.

Only the antenna pads and connections to feed and GND are present within this clearance area. The clearance area required is 6.0 x 4.0 (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 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. 16. 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. 17. Packaging 17.1 Optimal Storage Conditions Temperature -10ºC to 40ºC 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.
