sequence of wideband antennas
1, 2, 3, 4, sequence of prismatic polyhedron antennas
These antennas were invented by N2DT and G6GPR after simulation studies by N2DT, and designed to have 50 ohm driving point impedance over progressively wider bandwidths. N2DT intended them to be HF antennas for Ham Radio use, but G6GPR made them into microwave antennas for measurements in the laboratory. The fat conductors make the design dimensions far less critical, so these are "well behaved" antennas. The whole process is a combination of modern mathematical simulation tools together with insight derived from semiconductor physics, where many coupled identical elements create a band of frequencies from a single resonance.
