Abstract
A wide relative frequency band and reduced size-to-wavelength ratio antenna comprising essentially a first part in the form of a conductor ring and a second part in the form of a skirt respectively connected to the central and outer conductors of a coaxial feeder. The first part has a conductive path in the form of a circumference and one of its diameters; the central conductor of the feeder is connected to the mid-point of the said diameter. The second part is in the form of a skirt and has a conductive path formed by a circular ring connected to one of the ends of each one of a plurality of conducting strands having the form of broken lines inscribed in isosceles trapezoid forming an assembly defining the faces of a frusto-pyramid, while an annular and conical end member is connected to the feeder outer conductor and is in contact with the other ends of the strands.
