Abstract: In this paper we report the preliminary investigation on the novel Multi walled Carbon Nano Tube (MWCNT) based composites for Microstrip patch antenna design. The MWCNT based nano composite layer with two configurations viz. , PAni pTsA with MWCNT (Polyanilinepara-Toluene Sulfonic acid with MWCNT) and PAni NSA with MWCNT (polyaniline Naphthalene Sulfonic acid with MWCNT) above the conventional copper patch antenna was designed and studied using High Frequency Structure Simulator software (HFSS) in the X band of frequencies. The simulation results revealed that the Nano composite based antenna exhibits an excellent antenna characteristic with stable Gain and radiation pattern around 9.5 GHz to 10.5 GHz frequency range by using inset feed configuration. MWCNT based nano composite antenna is simulated and the performance is compared with a conventional patch antenna. The results shows that, insertion of MWCNT nano composite layer over the microstrip patch antenna increases its operation bandwidth up to 3.12 % without considerable degradation in other parameters. The proposed MWCNT nano composite antenna is finds application for stealth aircrafts.
