Built-in Antenna High-precision positioning Antenna full frequency band

Overview

The antenna supports multiple satellite signal frequency bands including GPS L1/L2/L5, BDS B1/B2/B3, GLONASS L1/L2 and Galileo E1/E5a/E5bz, and is suitable for a variety of high-precision positioning, navigation and timing (PNT) applications. By optimizing electrical performance and structural design, the antenna achieves miniaturization, high integration and easy installation while ensuring signal reception quality.

Key Features

• Multi-band support

The antenna supports the frequency bands of multiple GNSS systems, ensuring reliable satellite signal reception worldwide.

• High-performance LNA

The built-in low-noise amplifier (LNA) has a low noise figure and high gain, which effectively improves the sensitivity and anti-interference ability of signal reception.

• Good electrical performance

The output standing wave ratio (VSWR) is low and the output impedance matching is good, which ensures efficient signal transmission. At the same time, the antenna has high efficiency and low axial ratio, which helps to improve positioning accuracy.

• Miniaturized design

The antenna is compact in size and suitable for integration in miniaturized devices such as tablets, car navigation systems, etc.

• Excellent out-of-band suppression performance

Through the carefully designed filter, the antenna has excellent suppression performance in the out-of-band frequency band, which effectively reduces the impact of interference signals.

• Lightning surge protection

The antenna has lightning surge protection function, which improves the reliability and safety of the equipment.
