Fast 3D pattern synthesis for conformal antenna arrays with cross-polarization reduction

The development of fast methods aimed to generate a far-field amplitude pattern having prescribed characteristics and able to operate on conformal arrays is a fundamental topic in antenna array synthesis. In fact, in many practical applications the array has to be mounted on surfaces of various shapes, such as those of terrestrial vehicles, aircrafts, satellites and others. For such arrays, the cross-polar component of the far-field may be comparable with the co-polar one also when linearly polarized elements are used in the array. Thus, some synthesis methods have been proposed to reduce the cross-polarization [1-3]. This paper presents a fast iterative method for 3D pattern synthesis of conformal arrays that is able to generate a desired co-polar pattern simultaneously reducing the cross-polar one.
