Angular filter study to modify the beam of a high gain antenna (phase 1) / Jafar Shaker.: Co24-3/8-2006-1E-PDF
"Development of techniques to suppress radiation into regions close to the main lobe of a high gain antenna is the subject of this report. A cascade of Frequency Selective Surfaces (FSS's) was used as the building blocks of a 3rd order Chebishev filter as an angular filter that operates within the frequency band of the filter. Necessary theoretical development was undertaken to establish parallels between electromagnetic characteristics of an FSS and circuit parameters that are used in the realization of Chebishev frequency response. Experimental methods were devised to characterize the phase response of an FSS structure. Knowledge of the phase response of each individual layer proves to be critical in the overall design process of the Chebishev filter. Insight gained during the characterization of the filter was essential in the rather "gradual" process of the design and fabrication of test apparatus. This insight leads to guidelines about the tolerances and critical parameters in the design and operation of such cascade filters"--Abstract.
