ABSTRACT:
A single-element antenna system that provides a wide bandwidth and consistent polarization over the frequency range to which the antenna is impedance matched. In one embodiment, the wideband antenna system includes two parallel coupled sectorial loop antennas (CSLA) that are coupled along an axis of symmetry. In another embodiment, half of the coupled sectorial loop antenna is electrically coupled to a ground plane, where the antenna includes one pie-slice shaped sector and two arches. In alternate embodiments, sections of the sector can be removed to reduce the weight of the antenna system.
