2.5 Trace antenna designs
For a modular transmitter with trace antenna designs, see the guidance in Question 11 of KDB
Publication 996369 D02 FAQ – Modules for Micro-Strip Antennas and traces. The integration
information shall include for the TCB review the integration instructions for the following aspects:
layout of trace design, parts list (BOM), antenna, connectors, and isolation requirements.
a) Information that includes permitted variances (e.g., trace boundary limits, thickness, length,
width, shape(s), dielectric constant, and impedance as applicable for each type of antenna);
b) Each design shall be considered a different type (e.g., antenna length in multiple(s) of
frequency, the wavelength, and antenna shape (traces in phase) can affect antenna gain and must be
considered);
c) The parameters shall be provided in a manner permitting host manufacturers to design the
printed circuit (PC) board layout;
d) Appropriate parts by manufacturer and specifications;
e) Test procedures for design verification; and
f) Production test procedures for ensuring compliance.
The module grantee shall provide a notice that any deviation(s) from the defined parameters of the
antenna trace, as described by the instructions, require that the host product manufacturer must notify
the module grantee 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.
2.6 RF exposure considerations
It is essential for module grantees to clearly and explicitly state the RF exposure conditions that permit
a host product manufacturer to use the module. Two types of instructions are required for RF
exposure information: (1) to the host product manufacturer, to define the application conditions (mobile,
portable – xx cm from a person’s body); and (2) additional text needed for the host product
manufacturer to provide to end users in their end-product manuals. If RF exposure statements and
use conditions are not provided, then the host product manufacturer is required to take responsibility
of the module through a change in FCC ID (new application).
2.7 Antennas
A list of antennas included in the application for certification must be provided in the instructions. For
modular transmitters approved as limited modules, all applicable professional installer instructions
must be included as part of the information to the host product manufacturer. The antenna list shall
also identify the antenna types (monopole, PIFA, dipole, etc. (note that for example an “omni-
directional antenna” is not considered to be a specific “antenna type”)).
For situations where the host product manufacturer is responsible for an external connector, for
example with an RF pin and antenna trace design, the integration instructions shall inform the installer
that unique antenna connector must be used on the Part 15 authorized transmitters used in the host
product. The module manufacturers shall provide a list of acceptable unique connectors.
2.8 Label and compliance information
Grantees are responsible for the continued compliance of their modules to the FCC rules. This
includes advising host product manufacturers that they need to provide a physical or e-label stating
“Contains FCC ID” with their finished product. See Guidelines for Labeling and User Information for RF
Devices – KDB Publication 784748.
