Note:
The PCB strip antenna is available from Ethertronics, Inc. with or without
adhesive tape backing for mounting to a plastic case. For the component without
tape backing a non-conductive double sided adhesive tape can be used to fix the
antenna in place. The Ethertronics part numbers listed above come with a 50mm
U.FL cable attached to the PCB strip antenna. The 50mm cable length is the
minimum allowed cable length for use with the xPico Wi-Fi embedded device
server. For similar PCB strip antennas with longer cables consult with
Ethertronics, Inc. (
www.ethertronics.com
).
Lantronix provides a U.FL to Reverse SMA antenna cable in with the evaluation board
and sample kits for development work. These cables can be purchased from Lantronix
for production or supplied by an RF cable manufacturer. External antennas can be
purchased from the antenna vendor. Components for cable design should be selected
for low loss over the entire 2.4Ghz to 5.9Ghz signal range. The cable target impedence
should be 50 ohms.
