Summary:
This paper presents a novel reduced size dual band Printed Quadrifilar Helix Antenna (PQHA). Using meandering arm and dielectric loading techniques, a small dual-band antenna working in L-band for L1/L2 GPS application is realized with a good gain and a good circular polarisation. With this design the axial length of conventional PQHA is reduced by 73%. Measured results are presented to validate the concept.
