A Plant Growth Simulation Algorithm for Pattern Nulling of Linear Antenna Arrays by Amplitude Control

A method based on plant growth simulation algorithm (PGSA) is presented for pattern nulling by controlling only the element amplitudes of linear antenna array. The PGSA is a new and highly efficient random search algorithm inspired by the growth process of plant phototropism. Simulation results for Chebyshev patterns with the imposed single, multiple and broad nulls are given to show the perfor...

Software for Synthesis of Radiation Patterns by Linear Antenna Arrays

This paper presents the characteristics of a software developed on MatLab Scripts to obtain the synthesis of radiation patterns, using linear antenna arrays. Several classical techniques have been considered such as Schelkunoff method, Fourier series and transform methods, Woodward-Lawson method, Taylor line-source methods. In all those cases, algorithms were developed and the results agree wit...

Modified Differential Evolution Algorithm for Pattern Synthesis of Antenna Arrays

A modified differential evolution algorithm (MDE) for pattern synthesis of antenna arrays is proposed in this paper. By employing the novel strategies of best of random mutation and randomized local search, the convergence of standard differential evolution algorithm (SDE) is significantly accelerated. Five standard benchmark functions are optimized to testify the proposed algorithm by comparis...

Phase-Only Synthesis of Antenna Arrays Using Nonuniform Phased Sampling Method

Nonuniform Phased Sampling method is proposed to phase-only synthesize the power pattern of both linear and planar antenna arrays. This method modifies the conventional sampling method which is used for amplitude-phase synthesis. This method is based on assigning suitable phases to the sampling points of radiation pattern in order to reach desired amplitude of currents. Some examples are given ...
