Overview

This antenna is a Samsung seven-band satellite navigation and positioning antenna. The GPS, BD, and GLONASS antennas are composed of a 50*50*6mm stacked 40*40*4mm ceramic dielectric antenna, a bandpass filter, and a low-noise amplifier. This antenna can be used to receive GPS: L1, L2, L5; BD: B1, B2; GLONASS: L1, L2, L3 satellite positioning signals, suitable for PAD, car navigation, handheld devices and other equipment, can provide good positioning functions.

Key Features

Multi-System & Multi-Band Compatibility

Supports a wide range of satellite systems and frequency bands, including GPS (L1, L2, L5), BD (B1, B2), and GLONASS (L1, L2, L3), with auxiliary coverage of GALILEO bands. This extensive compatibility ensures reliable signal reception across diverse scenarios, meeting positioning needs of PADs, car navigation, handheld devices, etc.

High-Performance LNA for Superior Signal Processing

Equipped with a low-noise amplifier (LNA) featuring high gain (35±1.5dB) and ultra-low noise figure (<1.5dB), effectively enhancing weak satellite signals while minimizing interference. The LNA also offers excellent in-band flatness (±1.0dB) and out-of-band suppression (≥30dBc), ensuring stable signal output.

Optimized Antenna Design for Efficient Signal Reception

Boasts high antenna gain (≥3.0±0.5dBi), low VSWR (<1.5 at center frequency), and right-hand circular polarization with axial ratio <3.0dB, maximizing signal capture efficiency. Microwave anechoic chamber tests confirm reliable performance across key frequencies (e.g., 1575MHz peak gain 0.92dBi, 1200MHz peak gain 1.98dBi), supporting stable positioning.

Wide Environmental Adaptability & Flexible Installation

Operates in -40～+80℃ (storage: -45～+85℃) with 90% relative humidity resistance, suitable for harsh environments. Compact size (876523mm) and magnetic fixation simplify installation; SMA male connector with 5m RG174 cable ensures versatile integration into various devices.
