To obtainsuch a characteristic (at least approximately) a multi-elementlinear array is usually used. An array is linear whenthe elements of the ar-ray are spaced equally along a straightline. In a uniform linear array the elements are fed withcurrents of equal magnitude and having a uniform progressivephase shift along the line. The pattern of such anarray can be obtained by addingvectoriallythe field strengthsdue to each of the elements. For a uniform array of non-directionalelements the field strength would be E_T = E_0 \\vert1 +e^J\\psi+ e^J2\\psi + e^J3\\psi + ... +e^j^(^n-1)\\psi \\vert(1) where \\psi =\\betadcos\\textphi + \\alpha and\\alpha is the progressive phase shift between elements, (\\alpha is theangle by which the current in any element leads the currentin the preceding element.) Compute the pattern of such a linear array.","src":"stemez-ElectronicCommunications"}
