When you think of directional ham radio antennas, you probably think of a Yagi, cubical quad, or a log-periodic antenna. These antennas usually are in a horizontal configuration up on a high tower.

Scientists bend, not break, the laws of physics. Faced with limitations imposed by physics, laboratory researchers are generating antenna innovations by tweaking constructs to change the rules of the ...

U.S. Army officials seek to replace the commonly used device. For decades, the U.S. Army has relied on the ubiquitous whip antenna for an array of air and ground communications, but those antennas ...
