Abstract

This paper addresses the miniaturization of Quadrifilar Helix Antennas (QHA) for space applications. A new miniaturization technique based on an original combination of a modified fractal shape and a sinusoidal profile is proposed. Experimental and numerical (simulation) results show that the height of Compact QHA (CQHA) may be 70% shorter than the height of classical QHA without significant degradation of antenna performances.
