Abstract
Helical antennas are versatile, but since they have almost purely resistive input impedance, they are difficult to match to transmission lines. We provide a parametric analysis of a matching technique that claims up to 1:1 VSWR with post-fabrication tuning. Our results show that the matching technique is dependent of the geometry on the matching structure. Taking advantage of this, we present different geometries that provide broadband operation with up to 20\\% fractional bandwidth for -15dB return losses, achieved by modifying the geometry of the matching strip.
