GeoHelix®–P2 Embeddable Passive GPS Antenna
Product DescriptionBuilt on patented PowerHelix® fi ltering antenna technology, the GeoHelix-P2 embedded GPS antenna is the smallest quadrifi lar helix antenna available, providing high performance in diffi cult GPS applications. The GeoHelix-P2 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;
• the orientation of the device is random; or
• the antenna will be embedded in the device.
The GeoHelix-P2 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, the GeoHelix-P2 acts as its own filter, attenuating signals from common GSM and ISM frequencies by as much as 30dB without external filtering.
The GeoHelix-P2 embedded antenna builds on the industry-leading performance of the GeoHelix-SMP external GPS antenna, reducing its size by 30%, making it even simpler to embed in a product. The antenna is deployed with a plastic tuning sleeve to ensure on-frequency performance.
