The density tapered planar array antennas can be designed by element thinning. The method of element thinning employed here is the deterministic method that has been proposed for linear array antennas, and the modification of deterministic method for planar array antennas is described. Although the result by this method is comparable with one by the statistical method that has been used in many applications, this method is not iterative one and the result is unique. The sidelobe level, for example, is -25.51dB where the array contains 1818 elements arranged with a circular aperture capable of 3259 elements if fully filled.
