Georgia Tech Research Institute undertaking 100-to-1 bandwith antennas

Engineers at the Georgia Tech Research Institute (GTRI) are developing 16 inches square, three inches thick, three layers of metal foil fabricated flat antennas. The antennas come in computer-designed patterns using printed circuit board technology with 300 MHz and can perform job of five conventional antennas.

By using the method of electronic interaction between antenna elements known as 'mutual coupling' they have reduced antenna volume and weight. This would create a good potential for use on military aircraft, ships and ground vehicles and devices that would not need broad bandwidth - such as wearable antennas that could be incorporated into military uniforms or even tents.
