Abstract
A complex and intricate GNSS antenna that is created using inexpensive manufacturing techniques is disclosed. The antenna combines a loop antenna and a cross dipole antenna together, in a single plane, to create an optimal GNSS gain pattern. The antenna structure is symmetric and right-hand circular polarized to force correct polarization over a wide range of frequency and beamwidth. The feed structure is part of the antenna radiating element.
