Modeling the radiation field of a slot antenna in a finite size screen
A radiating structure based on a slot line has been investigated using a decomposition method in combination with the concept of induced electromotive forces. The influence of the size of a screen on the distribution of surface currents has been analyzed. Co- and cross-polarized radiation patterns of a slot rhombic antenna have been computed. It has been found that the slot rhombic antenna has broadside radiation in the 1.85-2.8 GHz frequency band.
