FXUB68070180C Datasheet, PDF (13/14 Pages) Taoglas antenna solutions – Embedded Flexible 4G LTE Wide Band Antenna

Application Note
Like all flex antennas, the FXUB68 Minima antenna performance is somewhat sensitive to the routing of the
cable during integration. The preferred routing is a “full wrap” or “half wrap”, as shown below where the
cable is routed around the long side of the device. Routing over the lower part of the device as shown will
also work well. An integration where the cable runs straight off will work, but the performance in the
900MHz band may not be optimal. Avoid running the cable up along the short side or wrapping it around
the short side, as these will not work. If a longer cable is needed to wrap around the long side and still reach
the module, this is ok, and a longer cable can be easily built. Keep the antenna at least 20mm away from
conductors in the end user device.
The FXUB68 can be integrated into assemblies over a small ground plane such as a PCB. The efficiency in
these cases can sometimes be higher than the antenna alone.
