Abstract: Dipole-antenna printed as strip on a dielectric substrate is more suitable for modern technology than the classical dipole in rod form .In this paper ,an improved radiation impedance formula of rod-dipole in free space was proposed by considering the edge effects at two ends and the feeding point .Based on the improved formula and the equivalent conversion between rod-dipole and strip-dipole ,thispaper derived a pair of simple and accurate formulas to convert the response of a strip-dipole on slab to that of an equivalent rod-dipole;the two formulas were obtained by using the Synthetic Asymptote (SA ) method .The validity and the ac-curacy of the formula were verified ,which is less than 2% ,which means that thesetwo formulas can be quite useful for the guidance of practical engineering design .
