A Near-Field Investigation of Two Uniformly Periodic Loop Arrays.
Abstract
The k-beta diagrams for two different uniformly periodic loop antenna arrays are determined from measured near field amplitude and phase distributions of waves traveling on the structures. It is found that there are frequency regions where these structures function as effective radiators. The directional characteristics of the radiated fields depend upon the relative phase and amplitude distributions of the near fields. The k-beta diagrams of these periodic antennas are used to predict the behavior of their tapered broadband versions. The results of this study demonstrate that providing appropriate conditions of phasing are met, backfire radiation can be established and, in turn, a successful broadband antenna can be designed.
