CAD for antenna systems

Computer methods for solving antenna problems are described and their advan tages and disadvantages discussed. No one program will deal with all possib le antenna problems and some expertise is required on the part of the user to judge which method is appropriate for a given problem. The better the co mputer facilities, the more complex the problems which can be solved, but t here are some basic limitations in the underlying physics of all computatio n electromagnetic (CEM) software. There are still shortcomings in the ease of use and user-friendliness.
