The Echo 2 is a T-bar dipole PCB antenna, tuned to quad band GSM/GPRS, 3G and WiFi frequencies. Measuring 75 x 25 x 1.7mm and has a peak gain of 2dBi.
The Echo2 antenna is perfect for applications that require a sensitive compact embedded antenna 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 really 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. Designed for embedded applications, the Echo 2 is commonly used for: waterproof / water tight designs, portable solutions and fits in small places but retaining its efficiency.
