The ultra-low profile SMD combines L1/L5 performance in a compact 35 x 35 x 4mm design, ensuring consistent gain performance.
Taoglas, a provider of antennas and IoT components, have introduced Inception, a GNSS L1/L5 ultra-low-profile “patch-in-a-patch” antenna. The HP5354.A* is the first antenna to offer dual-band stacked patch performance in a 35 x 35 x 4mm size. This design embeds the second antenna within the first without physically stacking them. The new dual-feed surface mount design (SMD) cuts antenna height by 50%, reduces weight, and saves space, making it suitable for GNSS applications that require precise positioning in limited space.
The antenna can replace single-band surface mount patches, improving the IoT device’s positioning accuracy from 3 to 1.5 metres without affecting dual-band L1/L5 performance. With a custom electro-ceramics formula, Taoglas’ antenna technology ensures performance and integrates into devices needing accurate GNSS.
This antenna is useful for applications like asset tracking, smart agriculture, industrial tracking, commercial drones, and autonomous vehicles that require stability, resilience, and precision. Previously, the industry used single-band GPS, but emerging bands like L2, L5, L6, and L-band provide cleaner signals, improved gain, and centimetre-level accuracy. This trend aligns with global GNSS technologies, including GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS, and SBAS.
Some of the key features of the “patch-in-a-patch” antenna include:
- Ultra-Low Profile SMD: Stacked patch L1/L5 performance in a single-patch solution.
- Compact Form Factor: 35 x 35 x 4mm, optimised for 70 x 70mm ground plane.
- Consistent Gain Performance: The dual-feed design ensures circular polarisation gain, effective even with antenna detuning or in-situ tuning.
“Taoglas has been designing and manufacturing reliable, high-performance GNSS antennas in-house for over 20 years, and we remain committed to investing in new antenna technologies,” said Dermot O’Shea, CEO at Taoglas. “We know electroceramic patches are still the most efficient way to receive circularly polarised signals, and before Inception, multi-band configurations required a stacked patch antenna, which added to height and weight. The HP5354.A—our latest innovation—means you can move to the dual-band without changing the footprint, size, and height of your current single-band GPS antenna.”
