CAD for antenna systems

Computer methods for solving antenna problems are described and their advantages and disadvantages discussed. No one program will deal with all possible 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 computer facilities, the more complex the problems which can be solved, but there are some basic limitations in the underlying physics of all computation electromagnetic (CEM) software. There are still shortcomings in the ease of use and user-friendliness
