Abstract :
This paper presents a new quadrifilar helix volute antenna using grounded coplanar waveguide (GCPW) infinite feeding baluns. This new quater-wavelength volute antenna provides small size, low cost, ease of mass production, and substantially improved elevation pattern coverage and circular polarization properties.
