Abstract

A computer tool (ORAMA) for the synthesis of linear antenna arrays is presented. The orthogonal method (OM) and the orthogonal perturbation (OP) method are used. The orthogonal method derives the excitation of the elements of the array, while the orthogonal perturbation method quantizes the excitation and determines the position of the elements. The user has the options to select the array geometry, the case study for a specific desired pattern, the method to be used, and the element type. Several design cases with various constraints are presented. ORAMA (a demo of the software is available at http://rcl.physics.auth.gr) has been designed as a Windows MDI application for the academic classroom, as well as for professional antenna engineers. A set of examples for different array patterns shows the usefulness of the tool.
