<p>An antenna device (20) 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 (21); a voltage source (22) 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 (24) coupled to the tube for supplying a radio frequency signal (25) to the conductive path for antenna transmission. A method for transmitting a short pulse signal without a trailing residual signal is also provided.</p> |
