Array antenna design at Syracuse Research Corporation using WIPL-D is demonstrated by two examples: a switched beam conformal array and a phased array. The conformal array is a cylindrical array of vertical column subarrays. The phased array is planar array of microstripline integrated balun dipoles. In both cases, theory is compared with measurement.

This paper compares WIPL-D results with measurements and with two other known commercial EM codes for the analysis of selected configurations of printed antennas. Four examples are tested, ranging from the basic square patch to less trivial multilayer structures with thick substrates. Simulated radiation pattern and return loss results are compared with measured data, for proper assessment of the accuracy. The study also compares efficiency, flexibility and user friendliness. Rather than trying to rank the codes, the objective of the paper is to present and discuss results from systematic tests, and show strengths and trade-offs of the code.
