Product Overview
Made of high-density ceramic dielectric material, these antennas feature small size, ultra-thin thickness and stable performance. With accurate internal circuit etching design, they achieve low VSWR, high gain and high radiation efficiency. Built-in LNA active amplification option is available to effectively enhance satellite signal reception and improve positioning accuracy in weak signal environments.
Featuring excellent anti-interference ability and temperature stability, the antennas support SMT automatic patch mounting for mass production. Passive and active types are optional with customizable specifications. They are ideal for IoT modules, wearable devices, drones, vehicle terminals, smart instruments and portable positioning devices.
