The Echo 31 is a Dual Band WiFi WLAN dedicated PCB antenna. This multiband antenna comes into its own when a congested 2.4Ghz network is a limitation and the device can utilise the 5GHz alternative band. The Echo 31 antenna can be used with WiFi, Bluetooth, Zigbee and ISM based applications. With a small footprint size of 50 x 15mm, the Echo 31 is perfect for those applications where internal space for components is limited or when using an external antenna is simply not appropriate. Common applications for the Echo 31 include: waterproof / water tight designs, customer self service kiosks and low power Zigbee.
