Abstract

We have developed a moment method program that analyzes arrays of waveguide elements on circular-cylindrical surfaces. The presence of a radome is rigorously taken into account by using the Green´s function of a multilayer circular cylindrical structure. Special attention is given to numerical treatment of the Green´s function when analyzing cylindrical antennas of large radii. The calculated results are compared with the measured S-parameters of the array with 54 waveguide elements. The agreement between measured and calculated results is very good.
