Introduction
The TG.22.0111 2G/3G monopole helical antenna operates from 824MHz to 2170MHz on
GSM-DCS-PCS-UMTS-CDMA-GPRS-EDGE-HSPA. Once mounted to an adequate ground-plane
it is a compact robust terminal antenna with high gain and stable efficiency in a small form
factor. Connection is made via straight SMA(M) connector.
Typical applications
- Remote monitoring
At only 49mm in height, with a hardened TPEE casing, this antenna is the ideal GPRS/UMTS
antenna for telematics devices where larger antennas cannot be used.
Like all small monopole antennas, it must be mounted on a ground-plane to radiate
efficiently. The antenna should be mounted at the edge of the ground-plane of the mainboard
of the device. See below charts for analysis of performance. A larger ground-plane of more
than 100mm is needed for stable performance on all bands. Also no metal should be used near
the antenna, with at least 20mm of clearance required, the more clearance the better.
For devices with ground-planes smaller than 100mm in length or where metal clearance is
not adequate, alternative larger antennas should be considered such as the TG.30. If small
size is needed, a custom tuned solution or a new design may also be necessary. Contact your
Taoglas regional sales office for support.
