VHF-UHF Phased Array Techniques. Part II. Mutual Effects in Finite Arrays of Slots.
Abstract
The analysis of finite planar arrays of slots is developed. This analysis includes as special cases the linear array of slots with weak coupling and the linear array with strong coupling. This strong coupling case has not been available heretofore in the literature. Likewise the analysis of the finite planar array is presented for the first time in this report. The degenerate or special case of the linear array with the weak coupling of slots is presented with experimental confirmation of results. The experiments of others were used to verify the finite planar array analysis. A complete and error free program has been written in Fortran IV language during this study. This program will enable the sponsor to fully utilize the advanced methods of calculation of array performance without the necessity of making expensive experimental models of planar arrays. This type of early design calculation also makes it possible to avoid 'blind spots' in the projected array performance. The analysis may be adapted to arrays using other than slot elements through the use of the same basic approximation methods as well as with full use of reciprocity and symmetry.
