Ethertronics has unveiled EtherHelix GPS, a small, stand-alone, Right Hand Circularly Polarized (RHCP) external GPS antenna. Measuring 35 mm in length, the EtherHelix GPS is 27 percent shorter than other antennas on the market with no performance trade-offs, the company said. It is designed for high-performance, mission-critical devices such as walkie-talkies, tough books, tough tablets, first responders, public safety, military applications and more.
EtherHelix can be tuned for various satcom frequencies and various polarizations (RHCP or LHCP). EtherHelix GPS is designed using Ethertronics’ patented Isolated Magnetic Dipole (IMD) technology providing high performance and efficiency in a small form factor.
EtherHelix GPS has a high tolerance to frequency shifts given the technology’s high RF isolation, which is designed to resist antenna detuning that can otherwise impair reception. EtherHelix GPS provides exceptional coverage inside buildings, vehicles or other areas where weak signals and signal reflection occur, the company said.
“GPS capabilities are critical for first responders and military applications. It is imperative that the antennas used in these devices are high-performance, small and rugged,” said Olivier Robin, general manager Americas and Europe at Ethertronics. “EtherHelix GPS is the most recent example of Ethertronics’ leadership in developing industry-first RF solutions to provide manufacturers with a way to differentiate their products and stand out in a competitive market. Already we have seen interest in our new EtherHelix GPS antenna given its best-in-class performance coupled with its smallest occupied volume.”
Given its reduced weight and size — 11.8 g and 35 mm long by 15 mm in diameter — manufacturers benefit from simpler integration for an array of GPS devices, Ethertronics said. In addition, the new GPS antenna’s capabilities include high selectivity, which minimizes the need for additional filters. EtherHelix GPS’s ruggedized design includes IP-68 protection from dust and water, as well as a standard SMA male connector for easy integration. The RoHS Compliant antenna is designed and manufactured in the United States.
EtherHelix GPS is commercially available now and is the first in a series of antennas for mission-critical applications.
