Antenna footprint The recommended host PCB footprint is below. 1 2 4 3 4 copper pads all 3.2 x 1.2 (mm) 10. Schematic The circuit for the antenna and the matching components is below. The RF feed connection and GND connections are critical to the function of the antenna, and must be followed as shown. This circuit can be used for the circuit capture of the host PCB. Pin 2 the feed is connected to Pin 1 (GND) as shown below here and is essential to the antenna function. Pi Network Antennas for Wireless Applications Product Specification SR42W009-PS-1.6 Page 7 Trogona Part No. SR42W009 11. 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 feed. 11.2 Matching Circuit The antenna requires a matching circuit that must be optimized for each 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 Pi matching network must be placed close to the antenna feed to ensure it is more effective in tuning the antenna.

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. 15. Hazardous Material Regulation Conformance The antenna has been tested to conform to RoHS requirements. A certificate of conformance is available from Antenova’s website. 16. Packaging 16.1 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.
