High-Precision Vertical Array Patch Antennas

Overview

The High-Precision Vertical Array Patch Antenna is a high-gain, advanced antenna system tailored for professional UAV applications, providing unmatched navigation, tracking, and control across multiple satellite constellations. It supports full-band coverage for GPS (L1/L2/L5), GLONASS (L1/L2/L3), BeiDou (B1/B2/B3), and Galileo (E1/E5a/E5b/E6), ensuring superior global positioning accuracy in diverse operational environments.

At its core, the system integrates a durable stacked ceramic patch antenna, further enhanced by four precision-crafted vertical antenna arrays positioned on each side. This innovative design maximizes signal reception and accuracy, while effectively minimizing the impact of signal degradation in complex terrains and urban areas.

Delivering 4.5 dBi high-gain performance with ultra-low signal loss, the antenna also boasts a wide beam width that covers a broad frequency range with impressive marginal gain. The advanced Low Noise Amplifier (LNA) features enhanced signal filtering, strong out-of-band rejection, reduced electromagnetic interference, and robust multi-path reduction capability. With its IP67-rated durability, the antenna is designed to perform reliably in the harshest environments, ensuring long-lasting performance in demanding applications.
