Design of linear sparse array based on the Taylor line source distribution element spacing

A Proposed Design Method for Sparse Array Antenna by Using the Spacing Coefficient Algorithm

“…us, we approach by developing a distance coefficient between elements based on the inverse of the reference continuous source distribution of excitation amplitude Taylor series [4] to adjust the distance between elements to the ideal distance reference of the half-wave array elements [19,20] and our previous work [17] as shown in Figure 1. e method is quite simple, and of course, it can also cut computational time when compared to using a generic mathematical algorithm method in the previous deterministic tapering technique.…”

“…rough the nonuniform distribution relation of the tapering amplitude with the distance between the elements of Figure 1, we can produce a synthesis and approach the distance coefficient as the following equation [17]:…”

“…While the amplitude excitation coefficient can be determined from the source distribution shown [17,21,22]:…”

“…where J 0 is the Bessel functions of the first type of zero order, l is the total length of the line source, and B is the Taylor oneparameter distribution algorithm, which can be determined by [23] as shown in Table 1. is form can be translated into array configuration with p even or odd number of elements, and the amplitude excitation coefficient for each array element can be determined by the following equation [17,[21][22][23]:…”

“…e synthesis of the distance coefficient between elements was developed from the Taylor line distribution algorithm, which has been used for a long time to calculate the excitation of uniform arrays [15,16]. However, this method has only been used in our early work on developing this method [17] and we continue to construct the procedure in this study.…”
