Summary:
in this work, a design of quadrifilar helical antenna with characteristics of compact, wideband and circular polarization is presented. It is achieved by combining the ways of tuning the different dimensions of the pairs of bifilars, and a feeding structure for providing the self-phasing technique. Both of simulated and measured results are reported in this study.
