Software for Calculating Radiation Patterns for Linear Antenna Arrays
نویسندگان
چکیده
This paper describes the characteristics of a software developed on MatLab Scripts to obtain the radiation patterns of linear antenna arrays using dipoles as the elements. The software includes, among several other options: the analysis and design of arrays with progressive phase, arrays with non uniform amplitude excitation and arrays with non uniform separation. Some special attributes of the software are the simulation through the straight calculation of the fields, the analysis of sensitivity and the behavior against frequency changes, as well as the use of the current distribution on the dipole calculated by the method of moments. Key-Words: Simulation, Antenna Arrays, Radiation Pattern, Dipole, Moment Method, Array Factor, Sensitivity of Antennas

متن کاملPhase-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 ...
متن کاملSoftware 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...
متن کاملPhase Only Synthesis of Antenna Patterns Using Iterative Restoration Methods
In this work, the method of iterative Fourier transform phase reconstruction, conventionally used in holography and optical image reconstruction, is applied to phase only synthesis of antenna patterns. The method is applied to two types of pattern synthesis problems: "main lobe beam shaping" and "side-lobe-level reduction". The proposed method is most useful in the efficient employment of attai...
متن کاملDevelopment a New Technique Based on Least Square Method to Synthesize the Pattern of Equally Space Linear Arrays
Using the sampled data of a desired pattern is a common technique in pattern synthesizing of array factor (AF) of antenna arrays. Based on the obtained data matrix, Least Square Method (LSM) is used to calculate the exciting coefficient of array elements. The most important parameter, which involves the accuracy and complexity of calculation, is the sampling rate of the desired pattern. Classic...
