摘要：
The subject invention relates to antennas having substantially greater bandwidth and low angle gain of the type for the transceiving of circularly/elliptically polarized electromagnetic waves. The antenna structure comprises a ground plane (11), a source (20) of linearly-polarized wave energy field associated with said ground plane, and a plurality of conductive elements (12) having an L-shape, said elements equally spaced from one another and equiangularly disposed about the sources, said plurality of elements being in a form of a circular arrangements, each element being so disposed as to fall on the circumference of the circular arrangement, each element lying in a common plane orthogonal to the linearly-polarized wave energy field provided by said source. The subject invention has special utility in motor and marine craft for communication and navigation.
