1. A circular polarized signal receiving antenna, comprising:
- an active element having first and second ends separated by a gap,the active element having a dimension between the first and second ends thereof corresponding to approximately one wavelength of a resonant operating frequency of the antenna;
a feed-point coupled to the active element,the feed-point 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, the feed-point is reactively coupled to the active element.

Abstract
A circular polarized signal receiving antenna (100) including 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, corresponding 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 reactively coupled to the active element.
