Inception Series – Multi-Band GNSS L1/L5 Low Profile Patch Antenna


Inception Series – Patent Pending, Innovative Multi-Band GNSS L1/L5 Low Profile Patch Antenna

The Taoglas Inception Series HP5354.A, is a multi-band GNSS passive patch antenna designed for optimum positional accuracy and positioning. It utilizes a patent pending, innovative ceramic patch within a patch antenna design with optimized gain for GPS L1/L5, Galileo, GLONASS and BeiDou bands and measures just 35*35*4mm.

This ground-breaking design allows customers to integrate a multi-band L1/L5 GNSS patch into devices where this would not have been possible before due to height constraints. At only 4mm in height, the HP5354 can be used in a variety of applications where typical stacked patch designs are too tall.

Typical Applications Include:

– Wearables

– Compact Asset Trackers

Precision Agriculture

– Navigation

– Industrial Tracking

– Autonomous Vehicles & Robotics

The HP5354.A has been tuned and tested on a 70 x 70 mm ground plane and exhibits excellent radiation patterns. The HP5354.A has been optimized to cover the bands required for the next generation of L1/L5 GNSS receivers that are currently on the market.

If you require an easy-to-integrate active electronic circuit for the HP5354.A, the Taoglas TFM.100B can be designed onto the device PCB alongside the antenna. The module features a SAW/LNA/SAW/LNA topology in both the low and high-band signal paths to prevent unwanted out-of-band interference from overdriving the GNSS LNAs or receiver. The SAW filters have been carefully selected and placed to provide excellent out-of-band rejection while also maintaining a low noise figure.

Care should be taken when integrating this antenna into a customer device. Patch antennas can be specifically tuned to customer-specific device environments, subject to NRE and MOQ. Contact your regional Taoglas customer support team to request these services or additional support to integrate and test this antenna’s performance in your device.
