Abstract :
Two pre-fractal printed quadrifilar helices antennas have been presented. These compact antennas offer good compromises between size and performances. The designs introduced in this paper reveal the feasibility of an axial length reduction between 30 to 40% without significant cross-polarization degradation. Experimental validations were presented at the conference.
