Abstract :
Dyadic Green´s function (DGF) find a good place in communication engineering in modelling micro strip lines and patch antennas at radio frequencies. The DGF relates electromagnetic fields with the source current in free space. Using simple geometry to define the dyadic Green´s function (DGF) in free space and then applied to a stratified media to find the components of Immittance matrix which is used in determining the resonant frequency, input impedance, radiation characteristics etc. of micro strip lines and phased antenna arrays at radio frequencies. This method can be easily applied to multi-layered printed structures in wireless networks as well. The derivation which introduces a method to model the printed structures without extra mathematical labour.
