Taoglas to show GNSS, cellular and Wi-Fi/Bluetooth antennas
Taoglas® will present its latest advancements in GNSS, cellular, and Wi-Fi/Bluetooth active and passive antennas at Embedded World 2025.
Taoglas will showcase its latest GNSS front-end technology, which enhances signal performance, simplifies RF design, and ensures greater reliability in high-precision positioning applications. This new development, specifically tailored for engineers involved in autonomous navigation, industrial automation, and asset tracking, facilitates system integration while maximising GNSS accuracy. Further details will be revealed at Embedded World.
Recently, Taoglas announced the Levity Series AHP24510 (L1/L2/L-Band) and AHP54510 (L1/L5/L-Band) directional patch antennas, which have been optimised for GPS, Galileo, GLONASS, and BeiDou satellite constellations.
Triangulation using multiple satellites enables quicker and more precise acquisition and locking onto signals, especially in urban areas. The L-Band capability means Levity Series antennas also work with high-precision GNSS correction services. Systems using these services typically achieve better than 200 cm positioning accuracy, aided by comparing signals from different frequency bands so that receivers can correct for ionospheric delays and other errors.
Two additional benefits of multi-band acquisition are integral redundancy, which, among other advantages, reduces satellite security blind spots and lowers energy consumption, as faster acquisition requires less system uptime, thereby saving power.
The primary applications for the AHP24510 and AHP54510 are wearables, navigation, transportation, robotics, precision agriculture, and autonomous vehicles.
The AHP24510 and AHP54510 are part of a fast-growing family of Levity multi-band products from Taoglas designed for high-precision applications. The Levity Series active antennas feature a 45 x 45 x 10 mm wide-band, dual-stacked patch design and a dual-feed low-noise amplifier (LNA) that provides 28-29 dB gain and includes a filter. The maximum antenna voltage standing wave ratio (VSWR) is 1:1 across a frequency range of 1207 MHz to 1603 MHz, while the passive antenna efficiency (excluding the LNA) varies from 39.93% at the lowest design frequency to a peak of 68.51% in the L1 band. These antennas utilise right-hand circular polarisation (RHCP) to minimise multipath interference, ensuring optimal signal reception and reduced losses. Cables and connectors are fully customisable.
