Nano Composites Based Microstrip Antenna for Stealth Applications

摘要

In this paper we explore using Nano composite material for radar stealth applications. An accurate Electromagnetic Model of the composite antenna is developed using 3D Electromagnetic high frequency structure simulator software (HFSS) for numerical analysis. Good agreement between computed results is shown for both copper and single walled carbon nanotube (SWCNT) based antennas. The SWCNT composite antenna shows stable Gain and radiation pattern over the X-band frequency range. The dispersion characteristic of SWCNT composite antenna shows its suitability for radar communication system. Using inset feed configuration, the results show that insertion of SWCNT nano composite microstrip patch antenna increases its operation bandwidth without considerable degradation in other parameters.
