Section 14 of RSS-210
The installer of this radio equipment must ensure that the antenna is located or pointed such that it does not emit RF field in
excess of Health Canada limits for the general population. Consult Safety Code 6, obtainable from Health Canada's website:

L'article 14 du CNR-210
Le programme d'installation de cet équipement radio doit s'assurer que l'antenne est située ou orientée de telle sorte qu'il ne pas
émettre de champ RF au-delà des limites de Santé Canada pour la population générale. Consulter le Code de sécurité 6,
disponible sur le site Web de Santé Canada: http://www.hc-sc.gc.ca/ewh-semt/pubs/radiation/99ehd-dhm237/index-eng.php
ANTENNA
CEL’s CMP4010 includes an integrated Printed Circuit Board (PCB) trace antenna. An optional configuration which uses a u.Fl
connector on the module allows the user to connect an external antenna. The CMP4010 has been certified with the PCB trace
antenna only.
The PCB antenna employs a topology that is compact and highly efficient. To maximize range, an adequate ground plane must
be provided on the host PCB. Correctly positioned, the ground plane on the host PCB will contribute significantly to the antenna
performance (it should not be directly under the module PCB antenna). The position of the module on the host board and overall
design of the product enclosure contribute to antenna performance. Poor design affects radiation patterns and can result in
reflection, diffraction and/or scattering of the transmitted signal.
For optimum antenna performance, the CMP4010 should be mounted with the PCB trace antenna overhanging the edge of the
host board. To further improve performance, a ground plane may be placed on the host board under the module; up to the antenna
(a minimum of 1.5" x 1.5" is recommended). The installation of an uninterrupted ground plane on a layer directly beneath the
module will also allow you to run traces under this layer. CEL can assist with your PCB layout.
The following are some design guidelines to help ensure antenna performance:
• Never place the ground plane or route copper traces directly underneath the antenna portion of the module
• Never place the antenna close to metallic objects
• In the overall design, ensure that wiring and other components are not placed near the antenna
• Do not place the antenna in a metallic or metalized plastic enclosure
• Keep plastic enclosures 1cm or more away from the antenna in any direction
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser)
gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and
its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful
communication.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et
d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage
radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope
rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante
