Abstract :
We have demonstrated that the volcano smoke antenna has conservatively a 10 to 1 bandwidth for both VSWR and antenna far-field pattern. Simulations over the same frequency range show excellent agreement with the experimental data, supporting the original idea that the volcano smoke antenna is a potentially very wide-band device.
