Abstract

In this letter, we present a nonmetallic antenna for wireless applications comprising a circular disk dielectric resonator (DR) on a duroid substrate, with carbon nanotube (CNT) composite material. The radiation characteristics of the proposed DR-CNT antenna such as impedance bandwidth and peak gain are studied both numerically and experimentally. The effect of the ohmic losses in the CNT composite on the antenna efficiency is investigated. The DR-CNT antenna has useful gain and radiation characteristics over the operating frequency band near the resonance of DR, and therefore the proposed antenna is a good candidate for wireless applications requiring a nonmetallic antenna.
