Wide-band antennas for reverberation chambers

Shielding effectiveness measurements in a dual vibrating intrinsic reverberation chamber results in very repeatable results for a large frequency range and large dynamic range. Antennas in reverberation chambers do not need any gain, but the losses should be low and the dimensions should be small. The conical and discone antenna are very suitable for this purpose. An optimized conical and a discone antenna have been designed, modeled and simulated and built. Experiments in free space show their wideband behavior. Measurements inside the reverberation chamber have been performed as well.
