This report details a numerical study on the impact of trace thickness on the antenna s input resistance when using the conductivities of the following materials copper trace, copper paint, silver-loaded ink, indium tin oxide ITO, poly-ethylenedioxythiophe PEDOT, carbon fiber composite, and carbon fiber. An antipodal planar dipole, measuring 305 mm x 4 mm and resonant at 450 MHz, is used for simulating the different materials. The antipodal planar model is constructed, measured, and compared to simulation results from commercial electromagnetic EM solvers to validate the structure. The results show that the antipodal structure performs as it should. The simulation results show that the ohmic resistance increases over the frequency band and decreases as trace thickness is increased. The efficiency is also improved as the trace thickness is increased.
