Abstract:
1. An orientation-independent antenna apparatus comprising: a first pair of triangular elements positioned opposite to one another; a second pair of triangular elements positioned opposite to one another and co-planar to the first pair of triangular elements; the apparatus farther including a six sided structure with the first and second pair of elements disposed on a selected surface of the six sided structure, and with four of the six sides being disposed adjacent and perpendicular to the selected surface; a vertical coupling element disposed within the six sided structure, arranged to parasitically feed the four of the six sides that are disposed perpendicularly to the selected surface having the triangular elements; and a phasing module for selectively combining the first and second pair of triangular elements for at least two polarization modes, with a first element of each pair providing a first combined signal, and with a second element of each pair providing a second combined signal, and such that in a first polarization 90 degrees from one another to provide a circularly polarized feed, and such that in a second polarization mode, the first and second combined signals are further combined together to provide vertically polarized feed.
