An antenna device for transmitting a short pulse duration signal of predetermined radio frequency that eliminates a trailing antenna resonance signal. The device includes a gas filled tube; a voltage source for developing an electrically conductive path along a length of the tube corresponding to a resonant wavelength multiple of the predetermined radio frequency; and a signal transmission source coupled to the tube for supplying a radio frequency signal to the conductive path for antenna transmission. A method for transmitting a short pulse signal without a trailing residual signal is also provided.

o Radar and antenna . We sold the gas plasma antenna technology in August 1999. In October 2003, we received a royalty payment valued at $75,500 comprised of $7,500 cash and $68,000 in marketable securities which were revalued to $17,409 at February 29, 2004. This represents the final payment related to the sale of the gas plasma antenna technology. The $24,909 was recorded as non-operating income during the nine months ended February 29, 2004. Our radar technology has not generated any revenue and we have suspended further development of this technology in order to concentrate our resources on the Ignite I microprocessor technology.

Good luck
