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 customer’s product. The matching circuit will require up to three components and the following pad layout should be designed into the device so the correct circuit can be installed: The antenna feed pad and the antenna ground pad are indicated in the drawing above. Additional pads are for mechanical attachment only and should not be grounded. 8 / 12 F1media 2.4GHz SMD Antenna F1304R 12. Antenna Integration Guide 12.1 Antenna Placement F1media M2M strongly recommends placing the antenna at the edge of the board. Maximum antenna performance is achieved by placing the antenna towards one of the corners of the PCB and with the feed point of the antenna as close to same corner of the PCB as possible. Additional ground and components near the antenna should be at a distance of at least 2mm. Where possible the antenna should be clear of ground from both sides, although the antenna can work well with a minimum clearance of D ≥ 2 mm as shown in the drawing above. 9 / 12 F1media 2.4GHz SMD Antenna F1304R 13.

Reference Board Matching Circuit 15. 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.

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. 12 / 12 F1media 2.4GHz SMD Antenna F1304R 17.
