PARASITIC EXCITATION OF CONCENTRIC RING CIRCULAR ANTENNA ARRAYS

PARASITIC EXCITATION OF CONCENTRIC RING CIRCULAR ANTENNA ARRAYS

A circular array consisting of a center element and two concentric rings each having six elements is described. The center element, and one element in the outer ring are driven; all of the others are parasites. This antenna is an extension of a parasitic previously developed by Simpson, which had on...

Zusammenfassung:A circular array consisting of a center element and two concentric rings each having six elements is described. The center element, and one element in the outer ring are driven; all of the others are parasites. This antenna is an extension of a parasitic previously developed by Simpson, which had only one ring. The second ring results in lower side lobes, and a slightly narrower main beam. Experimental results are given. (Author)
