Taoglas has released a new family of active, multi-band GNSS antennas. Levity Series’ AHP24510 (L1/L2/L-Band) and AHP54510 (L1/L5/L-Band) directional patch antennas are designed for GPS, Galileo, GLONASS and BeiDou satellite constellations.

These antennas offer improved performance through triangulation across multiple satellites, offering faster and more accurate signal acquisition and lock, specifically in urban environments. The L-Band capability allows compatibility with high-precision GNSS correction services, potentially achieving positioning accuracy better than 200 cm.

The multi-band antennas seek to offer integral redundancy to minimize satellite security blind spots and reduce energy consumption due to faster acquisition requiring less system uptime to save power.

The Levity Series active antennas feature a 45 mm x 45 mm x 10 mm wide-band, dual-stacked patch design with a dual-feed, low noise amplifier, providing 28 dB to 29 dB gain and filtering. They operate with a maximum antenna VSWR of 1-to-1 from 1,207 MHz to 1,603 MHz, and the passive antenna efficiency ranges from 39.93% to 68.51% in the L1 band. These antennas use right-hand circular polarization to mitigate multi-path interference.

The Levity Series includes other multi-band products for high-precision applications, such as the HP24510A and HP54510A stacked-patch passive components, and the TFM.120A surface-mount front-end module, which covers the full multi-band GNSS spectrum including L-Band.

These antennas are suitable for various applications, including wearables, transportation, robotics, precision agriculture and autonomous vehicles.
