The NECBSC high-frequency code solver is an efficient computational tool for solving electrically large problems. The features of the UTD-based algorithm in this solver is gainfully utilized to calculate the embedded element pattern of a 5×5 cylindrical dipole element array located before a PEC circular cylinder of electrical radius ka = 96.5. The central element of the dipole array which is kept...
In this paper two distinct methods by which creeping wave radiation field can be obtained from its eigenfunction series has been shown. For the continuing investigations, the results for the creeping wave propagation constant results will be presented at the time of the conference for validation.
Cavity-backed slot antennas have been a popular choice for element design in conformal array antennas. However in some cases it is actually desired to examine if microstrip patch elements can be used as replacements for slot antennas by embeding them in perfect conductors (PEC). The investigation reported here examines the VSWR and radiation patterns characteristics of a wideband U-Slot microstrip...
For realizing a low-sidelobe conformal phased antenna array using the techniques in D. Chatterjee and R.G. Plumb (1996), the array mutual coupling needs to be considered, with emphasis on location of the "blind spots". Therefore, the purpose of the results presented here is to furnish the reference solution for array scan element pattern including mutual coupling. The results would thus...
Conformal phased arrays on missiles and other tactical military platforms are affected in their radiation behavior by the local surface geometry. This controls the array blind spot locations and are dominantly influenced by the creeping wave propagation between array elements. However, for an arbitrary location pair on the curved surface, the appropriate creeping wave formulation can be different...
