This paper deals with a method for determining the radiation pattern of the omnidirectional antennas. The minimization method is used for the reconstruction of the FF antenna patterns from NF phaseless measurements on two cylinders in different distances from the antenna. The global optimization techniques were used for the minimization process. The paper is aimed to analyze the performance of the...
The genetic algorithm (GA) is used to optimize the loading of a wire to satisfy special requirements in the backscattering of a straight wire scatterer. The optimization goals may be satisfied in terms of a range of angles or frequencies, the side lobe level, the load values, beamwidth value, or a combination of the previous quantities. The backscattering level of this wire antenna is controlled by...
We have carried out the optimization of the simplest dual-mode horn that does not include the special cylindrical phasing section. Calculation of the horn characteristics has been performed by using a stepped representation of the conical section, with a subsequent application of the method of generalized scattering matrices, which more accurately accounts for all of the effects taking place when...
