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 ess
ential 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: The module complies with FCC radiofrequency radiation exposure
limits for uncontrolled environments. The device is installed and operated with a distance of
more than 20 cm between the radiator and your body." This module follows FCC statement
design, FCC ID: 2AL3B-XT-ZB6
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.
