The Echo 2 is a T-bar dipole PCB antenna, tune to quad band GSM/GPRS, 3G and WiFi frequencies. Measuring 75 x 25 x 1mm and producing a peak gain of 2dBi, this PCB antenna is perfect for applications that require a compact embedded antenna solution. Already proven in many applications where space is at a premium, this product 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.The Echo 2 PCB antennas are based on an efficiently tuned antenna element that is matched 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 general GSM applications that require a compact invention.

The Echo 2 is quad band GSM / GPRS, 3G / UMTS and WiFi/WLAN tuned antenna, designed to resonate to a high level at 850, 900, 1800, 1900, 2100 and 2400MHz and managing a peak gain of 2dBi. This PCB antenna is therefore a high performance, wide frequency band antenna, suitable for a host of wireless M2M applications that require an embedded solution. Its wide operating frequency band allows for worldwide cellular applications over the quad band GSM/GPRS networks and also high data transfer rates via 3G/UMTS and also short range WiFi data transfer on the 2.4GHz band.
