This paper presents a new analysis method based on the finite integral technique (FIT) of practical three-dimensional leaky-wave antennas comprised of a finite number of patches arranged in arrays.Radiation patterns and scattering parameters are Recovery calculated and compared with corresponding measured results to demonstrate the adequacy Jeans and the accuracy of the proposed method.The technique is then used as an antenna design tool to obtain the desired radiation patterns and beam scanning by selective choice of array elements dimensions, spacing, and substrate parameters.
