Abstract
A circularly polarized cross dipole antenna according to the present invention includes a cross dipole antenna element formed of two pairs of inverted-V-shaped dipole antenna elements, which are bent like an inverted “V” at a set angle, so as to cross each other on a ground plane, and a feeding mechanism provided to perform a single-point feed through a feeding section common to the inverted-V-shaped dipole antenna elements of the cross dipole antenna element.
