Analysis of the Radiation Mechanisms in and Design of Tightly-Coupled Antenna Arrays
… for thin planar or cylindrically conformal arrays of balanced elements fed over ground. These arrays have closely spaced elements to achieve wide bandwidths through mutual coupling. This dissertation develops two wideband designs in infinite, semi-infinite, and finite array configurations. …

Near field coupling between elements of a finite planar array of circular apertures
… in the calculations. A study of the effects of array size upon the performance of a triangular grid arrangement of circular apertures indicated that the elements near the center of a large phased array have similar radiation characteristics to those of an infinite array, except near the scan …

Scattering from periodic array of parallel strips
… field distribution between strips in a periodic array of parallel strips was modeled. The electric field integral equation (EFIE) together with method of moments was employed to solve the problem. The incident plane wave was assumed to be transverse magnetic (TM) and transverse electric (TE). The …

New Approach to finding Active Element Patterns for Large Arrays
… pattern analysis, for large phased array antennas, was created using Floquet's theorem. The classic approach to finding active-element patterns uses a full array simulation that can become slow and produce patterns that are specific to certain elements in the array, though basically …

Analyzing modal decomposition data of finite antenna arrays
Traditional antenna array theory is well suited for guiding the design of very large, uniform arrays. When an array is large enough one can often approximate that the array is of infinite extent, greatly simplifying the analysis of the structure and significantly reducing the cost of simulation. …
