Experimental validation of a frustum of cone antenna radiation patterns

This paper presents the experimental results relevant to a conical array formed by 216 passive array columns, each composed by 8 radiating elements, in terms of the embedded single column radiation patterns and sidelobes profile of the directive beam obtained grouping in array a suitable number of columns with an appropriate weighting function. Each step of the design is described, starting from the isolated radiating element, then inserting it into a radiating column, and finally in the complete conical array. For each stage of design, the comparison between the theoretical model and the measurement is reported. This array has been developed for a new 2D ubiquitous radar, named Omega360, that will be realized by Seastema, a Fincantieri SpA Company.
