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 accuracy 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.
