The HP54510A from Taoglas is a Passive Multiband GNSS Patch Antenna that operates from 1166 to 1610 MHz. It covers GPS/QZSS L1/L5, GLONASS G1, Galileo E1/E5a, BeiDou B1/B2a, SBAS, and L-band correction services, and is designed to achieve high location accuracy in urban environments. This RHCP-polarized GNSS antenna provides a stacked path construction that delivers a uniform gain with excellent axial ratio across the full operating bandwidth. When used on the base or rover in an RTK configuration, this antenna achieves cm-level accuracy. It provides a directional radiation pattern with a peak gain of up to 5.08 dBi and an efficiency of 83.5%.
The L1 band of the HP54510A antenna uses 2x orthogonal feeds that need to be combined in a hybrid coupler to achieve optimal axial ratio and gain across the operating frequency range. This GNSS antenna is available in a dual-pin, dual-feed ceramic package that measures 45 x 45 x 10 mm. It is ideal for timing synchronization, precision positioning in robotics, autonomous driving, telematics, and precision agriculture applications.
