Abstract :
The synthesis problems for the waveguide antennas according to the prescribed amplitude radiation characteristics in a wide frequency band are considered. At the same time, a series of various requirements to the amplitude radiation pattern and front-to-rear factor in the operating frequency band as well as outside this band can be taken into account when the variational statement of problem is carried out. The methods of successive approximations are used for solving the received nonlinear integral equations; the direct optimization of initial functionals by the gradient methods is applied too. The results of numerical modeling are shown.
