Overview

The TX-G033 is a passive multi-band GNSS ceramic patch antenna developed for embedded satellite positioning applications. It supports GPS L1/L2/L5 and is compatible with Galileo, GLONASS and BeiDou navigation systems.

The antenna covers upper GNSS bands around 1560–1615MHz and lower GNSS bands around 1176–1227MHz, allowing it to work with compatible multi-band GNSS receivers.

Its ceramic patch structure provides a compact antenna solution for navigation terminals, surveying instruments, UAV systems, robotics and industrial positioning equipment.

Final antenna performance depends on the PCB ground plane, nearby electronic components, enclosure material and installation position. RF verification in the complete device is recommended before mass production.

Key Features
