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).
Explanation: This module complies with FCC RF radiation exposure limits set forth for an
uncontrolled environment, This equipment should be installed and operated with a minimum
distance of 20 centimeters between the radiator and your body." This module is designed to
comply with the FCC statement, FCC ID is: 2AH3O-TL8822CSL.
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.
