In this research paper a carbon nano tube based barrel shaped dielectric resonator antenna design is proposed which is fed by a simple coaxial cable through a thin slot aperture. The resonant frequencies can be adjusted by adjusting DRA dimension and thereby TE11 and higher modes like TE13 mode can be energized with their resonant frequencies. For miniaturization purposes according to global demand a high permittivity dielectric resonator is best suited. The antenna design attempted here is suitable for two different band applications i.e. DCS (1710-1880 MHz) and WLAN (2400-2484 MHz) bands. The important parameters of design antenna like gain, radiation pattern and return losses are calculated here. The simulation results are well within the range of agreement with the results obtained through experiments.
