Echo 22G/3G/4G/WiFi compact 1/4 wave dipole PCB Antenna

The Echo 2 antenna is perfect for applications that require a sensitive compact embedded solution. Already proven in many applications where space is at a premium, this antenna is ideal as it is ground plane independent and compact making it a popular choice where a small size combined with efficient performance is critical.

Many small PCB antennas are a half dipole and where they really need a ground plane to be effective. The Echo 2 PCB antennas are based on an efficiently tuned, full dipole antenna element that can be used very effectively with a wide variety of RF & M2M modules operating on Cellular, 868 and 2.4GHz ISM band frequencies
