Abstract
A radiating structure, or antenna, includes an exciter patch which receives an excitation signal and a plurality of secondary patches which radiate the waves received from the exciter patch. The structure includes a reflective surface in the vicinity of the exciter patch and the secondary patches constitute semi-reflective surfaces. The combination is such that the waves radiated by the secondary patches are substantially in phase. The distance between the reflective surface and the secondary patches is substantially equal to half the wavelength to be transmitted. The structure maintains the purity of circular polarization over a wide angular sector.
