History of UWB Antennas

Lindenblad improved on the idea of a sleeve dipole element, adding a gradual impedance transformation to make it more broad banded. RCA chose Lindenblad's element (seen in cross-section in Figure 6a) for experimental use in television transmission.

Chapter 2. The Axial Mode Helix - A Historical Perspective

In 1940, Lindenblad [1942] filed a patent that described a helix traveling wave amplifier similar to the helix traveling wave tube. In Lindenblad's amplifier, the signal was applied to the beam using a grid in the electron gun.

Eggbeater Antenna

I continued to research antennas and next tested a Lindenblad , again made with twinlead. It was a little better than the turnstile but both harder to construct (I built it on a square cardboard box.) and even more of an eyesore.

Antenna Design in the Band 1 - 2GHz

Lindenblad arrays provide circularly polarized omnidirectional coverage from an antenna which is mounted around the supporting member, but again the complexity of the device - with four dipoles and four baluns - makes it very expensive to produce.
