ADELPHI, Md. -- A new, miniature, low-frequency antenna with enhanced bandwidth will enable robust networking among compact, mobile robots in complex environments. In a collaborative effort between ...
Wireless transmitters that operate at very or ultra low frequencies (0.3‐30 kHz) typically require some big antenna complexes to handle their communications. Scientists at the Defense Advanced ...
Antennas made for use with ground penetrating radar (GPR) are available in a variety of shapes and sizes. The biggest antennas generally radiate the lower frequencies needed to detect the deepest ...
