    Harxon has added to its helix antenna family with a series of four devices that are suitable for unmanned system applications.

    HX-CUX012A is designed with extremely low profile, making it suitable for integration into UAVs, surveying and monitoring devices. It reduces the overall weight of applications, enables multipath mitigation and more.

    HX-CUX005A is a solution for integrated helix antenna applications. It is designed with the integration of a GNSS antenna and Bluetooth/Wi–Fi antenna, enabling communication and navigation without mutual interference.

    HX-CH7609A is a low profile and small size housed helix antenna. It has comprehensive GNSS support including GPS, GLONASS, Galileo, BeiDou, as well as L-band correction services. HX-CH7609A features centimeter phase center repeatability and high gain at a low elevation. With signal filtering and multipath rejection, it provides reliable and stable GNSS signals.  

    HX-CHX600A is a high-performance helix antenna that receives GPS, Galileo, BeiDou, GLONASS, as well as L-band signals. With 4.2 dBi high gain, it provides suitable tracking performance at a low elevation angle. Its low noise figure design reduces transmission interference and improves signal quality.

    Harxon has introduced the HX-CUX005A to its family of helix antennas.

    The HX-CUX005A is an embedded helix antenna designed for high-precision positioning. It offers superior satellite signal tracking, including GPS, GLONASS, Galileo and BeiDou as well as L-band correction service.

    Upgraded with Wi-Fi and Bluetooth tunable (BT) for better integration, the HX-CUX005A is designed to be an all-in-one solution for surveying, unmanned aerial vehicles (UAVs), personnel and vehicle monitoring, and many more applications.

    The powerful antenna has Harxon’s patented D-QHA technology and multi-point feeding technology. It is able to provide reliable and consistent signal tracking with centimeter-level accuracy by exhibiting a stable phase center, 2.5-dBi high gain with ultra-low signal loss, wide beam width and exceptional low-elevation satellite tracking.

    In addition, the HX-CUX005A is optimized in circuit layout and equipped with robust pre-filtered low noise amplifier that guarantees excellent out-of-band rejection performance and strong multipath reduction capacity. In this way, unwanted electromagnetic interference is restrained for improved signal filtering over all GNSS frequency bands.

    The integration of Wi-Fi and Bluetooth (2.4 GHz/5.8 GHz) provides 1-dBi gain (typical value) to enable easy connection and configuration for mobile device users. Its highly integrated design simplifies development process and reduces costs for device engineers, Harxon said.

    Key Features of the HX-CUX005A

    • Comprehensive GNSS support: GPS, GLONASS, Galileo, BeiDou and L-band correction service
    • Centimeter phase-center repeatability, high gain at low elevation
    • Improved signal filtering and excellent multipath rejection
    • Weighs 10 grams in small form factor to facilitate integration
    • Integrated with Wi-Fi and Bluetooth tunable (2.4 GHz/5.8 GHz).

    Antenna maker Maxtena has launched an L1 L2 GPS/GLONASS active helix antenna for GNSS satellite applications. The new  antenna M1227HCT-A2-SMA antenna will replace its predecessor the M1227HCT-A-SMA antenna, which made its debut in 2010.The new antenna has been mechanically upgraded. It is packaged in a high-quality, durable IP67/68 sealed radome housing and terminated with a gold-plated SMA connector for RF feed/input and DC bias/power typically powered from the applications’ GNSS RF module.

     The M1227HCT-A2-SMA active helix design features Maxtena’s patented compact and light-weight Helicore Quadrifilar antenna technology and a built-in dual-stage low noise amplifier (LNA) and filtering, offering up to 30-dB gain for GNSS applications that use GLONASS and GPS in one radome housing with a single 50-Ohm SMA connector.

    The tiny antenna is designed for applications across various markets such as UAVs, GIS and wearable GNSS.

    Ethertronics Unveils GPS Helix Antenna for Mission-Critical Applications

    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.
