In this paper, we describe the synthesis of pencil-beam power patterns for antennas composed of concentric rings of uniformly excited circular patches. The synthesis is performed by simulated annealing, varying the radii of the patch rings so as to o

A method for fixing nulls with phase-only control in equispaced linear arrays is presented. The method uses the polynomial roots associated to the power pattern of an equispaced linear array along with the simulated annealing technique. In addition,

We describe a mobile communications antenna consisting of concentric rings of elliptically polarized circular patches. For certain sets of relative phases, optimization of geometry and excitation amplitudes by simulated annealing synthesizes a conica

The widely used first-order polynomial representation of the voltage reflection coefficient in multisection quarter-wavelength transformers is assumed. The roots of this polynomial are displaced iteratively to obtain, through the simulated annealing

A method for the array pattern synthesis in the presence of near-zone scatterers in the three-dimensional vector case is presented. The synthesis is based on the minimization of an objective function using the simulated annealing technique. In order

In this paper, a technique to minimize the variability of the scattering coefficients in multihole directional couplers is shown. The technique also controls important features of the frequency response like bandwidth and minimum directivity. Several
