The routing to the UFL connector or Switch must be 50ohms impedance, with suitable Ground
stitching vias along the route of the trace. The trace length should be kept to a minimum, locating
the module and antenna close together. Avoid routing the RF output trace over any other signals or
power planes, referencing only Ground to the RF signal.
Niche antenna guidelines are below, to use the design you must license the design from Proant AB.
All dimensions are to be followed, the cutout is present on all layers of the PCB.
The antenna must be placed at the edge of the PCB, with appropriate grounding around the shape.
The Antenna consists of the RF feed line (routed as 50ohms impedance) and cutout in the Ground
copper. To verify that the design is functioning correctly you must take a plot of it’s performance and
calculate peak gain to ensure the implementation is not over the specified limits stated in this
document. During production the antenna performance must be verified by measuring radiated
output power at a fixed frequency.
To test final integration you will be required to get the latest test files from

Any deviation(s) from the defined parameters of the antenna trace, as described by the instructions,
require that the host product manufacturer (integrator) must notify the module grantee (Raspberry
Pi) that they wish to change the antenna trace design. In this case, a Class II permissive change
application is required to be filed by the grantee, or the host manufacturer can take responsibility
through the change in FCC ID (new application) procedure followed by a Class II permissive change
application.
The modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules)
listed on the grant, and that the host product manufacturer is responsible for compliance to any
other FCC rules that apply to the host not covered by the modular transmitter grant of certification.
If the grantee markets their product as being Part 15 Subpart B compliant (when it also contains
unintentional-radiator digital circuity). The final host product still requires Part 15 Subpart B
compliance testing with the modular transmitter installed.
