The previously introduced method, called Zeros Matching Method (ZMM) is generalized in order to extend the desired patterns from only Chebyshev to any symmetric ones. Also, the desired patterns can be either sum or difference type. Some comprehensive examples are given to verify the effectiveness of the introduced ZMM method. Desired patterns in these examples are Chebyshev, Taylor, Cascade, and Stepped as sum types and equiripple as a difference type.

“…The synthesis of the radiation pattern in antenna arrays is a hot topic of research and several approaches are available in the literature. These approaches are analytical methods such as Taylor method and Chebyshev method or are optimization‐based methods . Another important factor that has to be considered in the synthesis of radiation pattern is the manufacturing tolerances in the excitation amplitudes.…”

Detection and correction of errors is a hot topic of research in the field of antenna arrays. The errors in the excitation amplitude result in the adulteration of the radiation pattern, and hence, the dynamic detection and correction of these errors are very important for proper maintenance of the radiation pattern. In this paper, a novel technique for detection and correction of errors in linear antenna arrays is presented. The analytical nature of the proposed approach makes it a viable alternative to the optimization techniques available in the literature. The error in the radiation pattern measured at an angle is expressed as a function of the individual excitation errors, and subsequently, several useful theorems and techniques are presented in the framework of error detection and correction. An exhaustive mathematical explanation followed by numerical simulations is presented to clearly illustrate the advantage of this method in the detection and correction of errors in antenna arrays.

“…Several methods are available for design of antenna arrays with specified Side Lobe Level (SLL) and beam width. These approaches are analytical methods such as Taylor's method and Chebyshev's method [11] or are optimization based methods [12][13][14][15][16]. Over the past few decades, many accurate techniques have been developed for antenna pattern synthesis [17][18][19][20][21][22][23][24].…”

“…It is based on a minimization algorithm and requires high computational time. The optimization based techniques [12][13][14][15][16][20][21][22][23] provide the flexibility to design any arbitrary radiation pattern but these techniques require high amount of computational time. An analytical technique which can predict the excitation amplitudes from the given design requirements would greatly reduce the computational time.…”

Abstract-This paper presents the theoretical framework for a new technique in the field of linear antenna arrays with amplitude control called error coefficient matrix. First of all, the array factor is expressed as a summation of contribution from the elements of the array. It will be shown that for small errors in excitation amplitude, the error in the overall radiation pattern at a given angle is a summation of errors contributed by the individual elements of the array at that angle. An error coefficient matrix is proposed, and its properties are discussed in great detail. The accuracy of the proposed method is investigated for varying levels of errors in weights and for varying number of error elements, using Monte-Carlo simulation. Finally, the applications of this new technique in the field of antenna arrays are presented.
