Abstract
An antenna includes a first antenna element comprising a pseudo-conductor material and forming a substantially closed polygonal loop around a center. The first antenna element conforms to a ground plane. The antenna also includes a plurality of transmission lines in the ground plane. Each transmission line comprises a conductor material, is extending radially outward from a feed end towards an outer end, is electromagnetically coupled to the first antenna element at a crossover point at which the transmission line crosses over the first antenna element, and is coupled, at the center, to a corresponding feed line. The antenna further includes a feed circuit for exciting the plurality of transmission lines to cause the antenna to emit in a predetermined direction and using a predetermined polarization mode.
