Antena Gps Geohelix-p2 Pasiva Sarantels Itytarg

Product Description

Built 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-fi eld to a very small volume, therefore materials
near the antenna have negligible de-tuning effects and the antenna maintains its pattern and
effi ciency in the presence of dielectric loading. As a dielectrically-loaded antenna, the GeoHelix-P2
acts as its own fi lter, attenuating signals from common GSM and ISM frequencies by as much as 30dB
without external fi ltering.

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
