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. Pi Network Antennas for Wireless M2M Applications Product Specification Page 7 Mutica Part No. SR42W001 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 track so the characteristic impedance of the co-planar transmission line 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 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.

Ideally Pin 1 should be closest to the PCB edge. Pin 1 marker to PCB edge The antenna requires a copper clearance on all PCB layers under the antenna section. The clear-out area is defined below. The clearance is minimal but must be followed for the antenna to function correctly. 13.4mm 5.7mm 0.5mm Clearance area Host board copper Antennas for Wireless M2M Applications Product Specification Page 9 Mutica Part No. SR42W001 For locations that are not on the corner the following clearances are required from each side of the antenna to GND. 5mm from antenna edge 16.7mm 0.5mm from antenna edge Centre PCB placement example Antennas for Wireless M2M Applications Product Specification Page 10 Mutica Part No. SR42W001 12.2 Host PCB Layout The host PCB must ensure the footprint and clearance meets the antenna specification. An example of the PCB layout shows the antenna footprint with clearance. The antenna uses solder mask defined pads. Pin 2(GND) is shown directly connecting to the GND in the shortest route. The feed connects to the matching circuit close to the antenna. Example host layout Below shows the antenna footprint and clearance through all layers on the PCB. Only the antenna pads and connections to feed and GND are present within the antenna area Example host layout Antennas for Wireless M2M Applications Product Specification Page 11 Mutica Part No. SR42W001 13.0 MIMO Application example. Mutica works well in multiple antenna systems with simple integration to ensure good isolation between antennas. Below is an example of a 2 X MIMO system. 33mm Antenna 1 Antenna 2 Two antennas placed perpendicular to each other. Both antennas were optimised and matched for the same bands using the Antenova evaluation PCB. An S21 measurement between these antennas shows good isolation of
