Abstract
A multi-rod broadband antenna consisting of a plurality of elementary radiators arranged as directrices of a cylinder each consisting of a conductor surrounded with a ferromagnetic core designed so that each one has a resonant frequency value different from any other one, the resonant frequency values being related so as to form a series. The arrangement of the rods around the cylinder is such that the frequency values of two adjacent rods do not correspond to two adjacent terms of the series.
