Sarantel’s GeoHelix-P3 Passive GPS Antenna offers unbeatable performance in the industry’s smallest package.
The GeoHelix-P3 was designed from the ground up to be embeddable, delivers stable performance in all modes of use, whether it’s measured in free-space or surrounded by lossy dielectric materials.
Ideal uses for the Geohelix-P3 GPS Antenna mobile phones, smartphones, GPS/Bluetooth® navigation devices, and tightly integrates GPS devices with multiple radios that require high positional accuracy. Can be integrated into handheld or body-worn devices
The Geohelix P3 may achieve an up lift in gain once integrated into device.
Geohelix-P3 Product Summary GPS L1-band quadrifilar helix antenna Integral balun Requires no ground plane High isolation from platform rejects common-mode noise Negligible proximity de-tuning No embedding sleeve required Constrained near-field does not interact with nearby components or the user Strong circular polarization Stable impedance Broad beamwidth Easy to embed - predictable performance RoHS compliant |
