ANALYSIS OF EQUIVALENT APERTURE OF CURVILINEAR ANTENNA ARRAYS

Abstract

The article presents the results of the analysis of equivalent aperture of curvilinear antenna arrays on the basis of the obtained mathematical models. The equivalent aperture of the curvilinear antenna array is a projection of the arc on the plane, which is perpendicular to the maximum emission direction or to the direction of electromagnetic waves receiving. Feature of the curvilinear antenna array is the antenna elements arrangement along the arc of the ellipse with different orientations and arbitrary parameters. The dependencies of the equivalent aperture curvilinear antenna array of scanning angle were obtained. It is reported the possibility of increase the equivalent aperture of curvilinear antenna array in given sector of scanning angles.
