▎ 摘 要
In this paper, a conductive layer is developed by printing a graphene nanoparticles-based conductive ink on the silk fabric showing surface resistance of 2.3 Omega S-1 and conductivity of 0.435 x 10(5) Sm-1, respectively. The printed silk fabric is utilized to fabricate TM02 mode wideband antenna for aeronautical radio-navigation applications centered at 4200 MHz. Excellent -6dB impedance bandwidth of 26.4% is obtained by incorporating a patch-ground shorting stub. The antenna has reasonable radiation efficiency above 74% including packaging losses and conical radiation pattern at higher order mode. The simulation and measurements are performed considering practical scenario showing excellent measured results.
