Antenna development

Through Defense Department funding, ASI Technology Corp. of Henderson, Nev., has developed a prototype of an ionized, gas-based antenna that produces less electromagnetic interference than metal antennas, opening a potential market for stealthy and point-to-point radio applications.

Because the gas, held in glass or ceramic tubing, is ionized only when signals are sent or received, the type of inherent interference usually found in fixed-location metal antennas is minimized.

The company is also developing accompanying signal-processing software to direct signals to specific locations, which would allow users to set up point-to-point, rather than broadcast, communications.
