Sarantel Helix Antenna

GeoHelix®–P3

INTERNAL PART NUMBER:1010062

Passive GPS Antenna for Mobile

Phones and Tightly integrated GPS Devices

Product Description

Built on patented PowerHelix® filtering

antenna technology, the GeoHelix-P3 is ideally

suited for mobile phones and tightly integrated GPS

devices with multiple radios that require high positional

accuracy. Unlike other conventional antennas, P3 achieves an uplift in gain once integrated into the customer’s product.

The GeoHelix-P3 antenna is ideal in applications where:

*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; P3 does not need

a ground plane.

*the orientation of the device is random; or

*the antenna will be embedded in the device.

The GeoHelix-P3 antenna is balanced. This 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. The GeoHelix-P3 is 50% smaller than P2, and ideal for embedded applications. The GPS performance of the P3 antenna is significantly enhanced when integrated appropriately into the customer’s product. The antenna does not require a sleeve to de-tune it to GPS frequency.
