Abstract
A novel traveling wave antenna, the chain antenna, is described. It consists of a ground plane close to which is a chainshaped conductor along which propagates a TEM wave. The loops of the chain are rectangular with typical dimensions of 0.4 wavelength times one wavelength. Several chain antennas can be connected in parallel giving a grid antenna. The grid antenna has a linearly polarized frequency scannable pencil beam and only one feed point per hundreds of radiating elements which makes it especially suitable for HF, VHF and UHF frequencies when high gain antennas are needed.
