Abstract
An elliptically polarized antenna is disclosed which includes a conductive mast having at least one elongated slot extending longitudinally of the mast at the outer periphery thereof and wherein energy is fed to the slot for exciting horizontally polarized waves. A pair of conductive elements are associated with each slot for exciting vertically polarized waves. This includes first and second elements each having a connecting end portion extending transversely from and connected to the mast near the midpoint of one elongated side of the slot with the element having a pair of free end portions extending in substantially opposing directions parallel to the slot. The free end portions have their respective lengths chosen relative to each other for purposes of controlling the split of the radiated energy between the horizontally and vertically polarized waves.
