ABSTRACT:
An orientation-independent antenna presents a circular polarization characteristic to incoming waves such that these waves are detected regardless or polarization and angle of arrival. The antenna includes crossed vertical loops and a horizontal loop, with the loops being phased to provide the circular polarization characteristic. In one embodiment, the antenna includes a number of elements on the faces of a cube, or the elements are positioned on the surface of a sphere. In another embodiment, the antenna is given both a right hand circular polarization characteristic and a left hand circular polarization characteristic in two different channels to provide for double the data throughput.
