The antenna systems synthesis according to the amplitude characteristics under condition of electromagnetic compatibility

The synthesis problems for two types of antennas are considered on the additional requirement of the electromagnetic compatibility. The variational statement of the synthesis problems consists in minimization of functional presented the mean-square deviation of the prescribed and synthesized amplitude radiation patterns together with additional summand that allows to minimize the field values in a near zone. The other functional allows to maximize the front-to-rear factor in the given range of frequencies and to minimize it outside of this range. The solutions of analysis problems are presented in explicit notation or as series of computing procedures that to a considerable degree simplifies the process of solving the synthesis problems.
