An ink-reducing printed rectangular CPW antenna design via selective area thickening

In this paper, we present an ink-reducing printed rectangular CPW antenna structure by defining a proper selective area for thickening the conductive ink layer. In this design, the microstrip feed line and the small section of ground elements near the microstrip feed line are made thicker than the other antenna areas. The simulation results illustrate that the proposed printed antenna structure can significantly reduce the conductive ink consumption by as much as 55% of the conventional flat printed antenna.
