This is an active multi-frequency, high-accuracy, GNSS antenna for the GPS L1/L2, Glonass G1/G2, Beidou B1/B2/B3, Galileo E1/E5B bands. helix antennas for GNSS satellite communications. helix antennas operate across several satellite networks including GPS, Iridium, Galileo and GLONASS.

 

The antenna adopts a four-arm spiral structure with a relatively stable phase center, which reduces the influence of the antenna on the measurement error; The antenna gain is high, the beam pattern is wide, and the effect of receiving low elevation signals is good, ensuring that the antenna can receive the satellite in different attitudes; The antenna is equipped with a high-band out-of-band suppression low-noise amplifier circuit, which can effectively resist external electromagnetic interference, and has low power consumption to ensure the endurance of the device; The antenna is small in size and light in weight, and is suitable for use on various devices that require antenna weight, such as drones and various handheld terminals.
