Claim Text:
1. An antenna system comprising: a substantially nonconductive substrate; a resistive layer disposed on said substrate, a feeding element; and a transmission line coupled to said feeding element; wherein said resistive layer has a topology defining a peripheral boundary enclosing an area of said resistive layer, wherein said resistive layer comprises a metal compound such that said resistive layer is partly electrically conductive; wherein said topology has at least one edge having a smooth configuration and a shape according to an elliptical function, said topology being configured to reduce a plurality of losses caused by a current density flowing within said area, by a sufficient extent so as to enable said resistive layer to radiate an electromagnetic signal with a radiation efficiency of between approximately 10% and 90%; wherein said resistive layer is adapted to be conformal to an area of said substrate; and wherein said topology is configured such that an input impedance at said feeding element substantially matches an input impedance of said transmission line coupled to said feeding element.
