SL1206 Sarantel GPS Active Antenna

the SL1206 surface-mount high-gain GPS antenna is the smallest active quadrifilar helix antenna available.

• the device is handheld, body-worn, or otherwise surrounded by high-dielectric materials that would de-tune conventional antennas;

• the antenna is tightly integrated with other antennas, e.g., Bluetooth/GPS receivers or GPS/GSM mobile phones;

• there are tight constraints on the size of the device or the amount of space allocated to ground

planes;

• the GPS receiver requires 20dB or more of input pre-amplfication;

• the orientation of the device is random; or

• the antenna will be embedded in the device.

The SL1206 antenna is balanced, which isolates it from the device and enables the antenna to reject

common mode noise resident on the device ground plane. The construction and materials of the antenna constrain its near-field to a very small volume, therefore materials near the antenna have negligible de-tuning effects and the antenna maintains its pattern and efficiency in the presence of dielectric loading. As a dielectrically-loaded antenna with a high-performance SAW filter, the SL1206 antenna effectively attenuates signals from common GSM and ISM frequencies by as much as 30dB, minimizing the need for additional filtering.
