Pattern Synthesis of Conformal Arrays
Abstract
Exact element patterns computed from expressions of two potential functions representing the model fields of arbitrary apertures on a conducting cone were compared with measured patterns. Circumferential and radial slots 6.22 lambda from the tip of a 10 deg half angle cone were used in the pattern measurements. Measured and computed patterns are in very good agreement. During this same period, an asymptotic approximation of the contour integrals representing the fields of the circumferential slot was carried out, resulting in approximate expressions for both field components. These expressions describe the component fields in terms of optical, transition and diffraction fields. The diffracted field is a product of a frequency-independent angular function and a simple function containing the position of the radiating element. Such representation of the fields is better suited for numerical computation than the modal series. Recommendations for further investigative work on the topic of conformal arrays are also included.
