Abstract :
Experimental properties of a flat cylindrical array with circular polarisation and omnidirectional radiation are presented. The thickness of the array wrapped on a perfect conducting cylinder is 0.04¿0. A bandwidth of 10% has been obtained. It is now possible to decrease the thickness by a factor 2 (i.e. to 0.02¿0), when using a short-circuited elementary source instead of a flat folded dipole, and yet retain the same band-width.
