Antenna design turns entire vehicles into broadcasting equipment

High-frequency antennas transmit radio waves across vast distances and even over mountain ranges using very little energy, making them ideal for military communications. These devices, however, have one big problem: They need to be huge to operate efficiently.

Instead of adding more bulk, University of Wisconsin–Madison engineers are working to increase the effective size of antennas by turning the military vehicles that carry them into transmitters — using the structures that support the antennas themselves to help broadcast signals.
