“…Different antenna technologies including shaped reflectors, polarization filtering, aperture sharing, etc., are simultaneously utilized in designing a DGR antenna system. Although aspects like reflector shaping [1]- [3], basic steps in electromagnetic analysis of DGR antenna [4], [5], and scattering from strip grids [6], [7] have been reported, minimal exposure has been given to RF impact analysis of intercostal structure (IC structure) [8], [9], wherein simple configurations consisting of only IC ring and stiffener posts are analyzed. In this letter, we present an efficient method of modeling a detailed dielectric IC structure and its impact analysis using method of moments (MoM) in conjunction with physical optics (PO) for conducting elements.…”

A modeling and analysis approach is presented to accurately predict the RF impact of intercostal structure on the rearshell performance of a dual gridded reflector (DGR) antenna. Hybrid physical optics method of moments (PO-MoM)-based electromagnetic analysis capability has been effectively utilized. The intercostal ribs have been identified as the main cause of copolar gain degradation and pattern distortion with smaller contribution from the intercostal ring.Index Terms-Dual gridded reflector (DGR), intercostal, method of moments (MoM), pattern distortion, physical optics (PO).
