Disclosed is a circularly-polarized antenna comprising a flat conducting ground plane, a radiator, and an excitation system disposed between the radiator and the ground plane. The radiator comprises a plurality of conducting segments separated from each other by a first dielectric medium and separated from the ground plane by a second dielectric medium. The plurality of conducting segments are symmetrically disposed about an antenna axis of symmetry orthogonal to the ground plane. The excitation system comprises a flat conducting exciter patch and four excitation sources with phase differences of 0, 90, 180, and 270 degrees. The excitation sources are generated on two orthogonal printed circuit boards.

Compact circularly-polarized antenna with expanded frequency bandwidth

Compact antenna systems for reducing the reception of multipath signals are disclosed. An exemplary antenna system comprises a ground plane, a receiving antenna disposed above the ground plane and providing an output signal of the antenna system, and a passive antenna disposed below the ground plane.
