Abstract:
An orientation-independent antenna that presents a circular polarization characteristic to incoming waves such that these waves are detected regardless or polarization and angle of arrival is provided with shorts across elements thereof that provide for crossed vertical loops and a horizontal loop to lower the VSWR at the lower frequencies of the antenna. 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.
