ABSTRACT:
An antenna for receiving and/or transmitting circularly and linearly polarized RF signals includes a circularly polarized radiation element and a linearly polarized radiation element. The radiation elements are disposed co-planar and spaced apart from each other on a pane of glass. The linearly polarized radiation element is fed with a phase-shifted signal line. A ground plane is disposed parallel to the radiation elements to sandwich a dielectric of air. The antenna produces the effect of tilting a radiation beam from a higher to a lower elevation angle to achieve a higher gain at lower elevation angles.
