Approach to a printed quadrifilar helical antenna meshing with the FDTD method

摘要

In this paper, an analysis of printed quadrifilar helical antennas (PQHAs) using the FDTD method is presented. We develop an in-house software taking into account the dielectric substrate. A tape form meshing is used in modeling the PQHA strip. A good agreement observed between theory and experimental results proves the validity of the method used by the in-house code for the PQHAs.
