Antenna connectors
This section provides an overview of the different antenna options for the external antenna connectors. The
main antenna connector port is mandatory while the MIMO antenna connector is optional and used only in
MIMO applications.

The sections below list the antennas that are included in the radio type approvals of the module. For each
antenna, the "Approvals" field defines in which test reports the antenna is included. Definitions of the
«Approvals» field are:
•
FCC - The antenna is included in the FCC test reports and thus approved for use in countries that accept
the FCC radio approvals, primarily US.
•
IC - The antenna is included in the IC (Industrie Canada) test reports and thus approved for use in
countries that accept the IC radio approvals, primarily Canada.
•
R&TTE - The antenna is included in the R&TTE test reports and thus approved for use in countries that
accept the R&TTE radio approvals, primarily the European countries.
•
MIC - The antenna is included in the Japanese government affiliated MIC test reports and thus approved
for use in the Japanese market.
In general, antennas with SMD connection, Reverse Polarity SMA connector or U.FL connector are included in
FCC, IC, R&TTE and MIC radio tests. The antennas with SMA connector are included in R&TTE and MIC radio
tests but not in FCC or IC due to FCC/IC regulations.
The external antennas are connected to the board through U.FL connectors. Some of the antennas are
connected directly to the U.FL connector of the board and some are connected using an SMA or reversed
polarity SMA connector through a short U.FL to SMA or reversed polarity SMA adapter cable. Antenna
accessories and recommended antennas can be found in Appendix B.

Internal antenna design
Keep a minimum clearance of 5 mm between the antenna and the casing. Keep a minimum 10 mm free space
from metal around the antenna including under. If a metal enclosure is required, ODIN-W260 with antenna
connectors has to be used.
It is recommended to place the ODIN-W262 module so that the internal antenna is in the corner of the host PCB
(Pin A18 should be in the corner) as seen in Figure 5. The antenna side (short side closest to the antenna),
