Closed-form expressions of spatial electric field Green's functions of micr
ostrip structures are presented. These expressions are accurate for a radia
l distance from one hundredth to five wavelengths. Numerical spatial Green'
s functions are efficiently calculated by applying fast Hankel transforms (
FHT). These numerical functions are then used to obtain the closed-form exp
ressions in terms of a sum of complex exponentials using the matrix pencil
method. Numerical results from this method compare well with those obtained
by direct numerical integration. Owing to the utilisation of an FHT algori
thm to calculate the Sommerfeld-type integral, the present method is very e
fficient in obtaining the spatial electric field Green's functions.
