A circular polarized signal receiving antenna includes an active element having first and second ends separated by a gap. A dimension of the active element between the first and second ends thereof corresponds to approximately one wavelength of a resonant operating frequency of the antenna. A feed-point is coupled to the active element, wherein the feed-point is located approximately one-quarter of the wavelength from the first end of the active element and approximately three-quarters of the wavelength from the second end of the active element. In one embodiment, the feed-point is coupled to the active element.
