Annotation
Two shapes of antenna elements have been investigated and compared to obtain phased antenna arrays with circular polarization in the far field; a feed network providing a Chebyshev distribution of current amplitudes and uniform distribution of phases has been designed for 4×4 arrays; phased arrays with modified square and circular patches have been designed and compared, providing sidelobe reduction of up to −26 dB.
