Omnidirectional bonus for miniature GPS antenna
Antenna specialist Sarantel has announced the PowerHelix GPS-P, a miniature GPS antenna which is omnidirectional and therefore tolerant of the orientation of the GPS receiver.
Novel GPS antenna picks up more satellites
The GeoHelix-H is a new-technology high-gain active antenna for portable GPS receivers which enables more satellites to be acquired than conventional patch devices.
The new GeoHelix-P2 antenna employs a revolutionary new feed system that further isolates the antenna from the radio platform, enhancing the already remarkable noise immunity characteristic of all PowerHelix filtering antennas.
This new feed system repositions the impedance matching element to the top of the antenna, stabilising the impedance transformation function of the feed and shrinking its size significantly.
Applied to the new GeoHelix-P2 passive GPS antenna, the total volume of the antenna is reduced by 30% when compared with the GeoHelix-SMP antenna.
Simplifying the feed system further leads to a 10% improvement in peak gain, with the GeoHelix-P2 antenna typically achieving -2.8dBic at zenith without a ground plane.
The GeoHelix-P2 retains the GeoHelix family's excellent circular polarisation pattern, with broad beamwidth for low-to-horizon satellite reception, and immunity from proximity tuning effects.
With its reduced size, simplified feed, and immunity to common mode noise and proximity tuning, the GeoHelix-P2 is the simplest antenna available for embedded applications, like PDAs, smart phones, and other handheld navigation devices.
David Wither, CEO at Sarantel said: "The GeoHelix-P2 clearly demonstrates our drive for continuous improvement in our product and technology".
"It represents not just a leap forward with our technology, but also with our production capability and our responsiveness to the marketplace".
"Customers have received the Geohelix-P2 with enthusiasm - I expect big things from this little antenna".
