Triangular dielectric-loaded monopole antenna

Abstract

The experimental study of the equilateral-triangular dielectric loaded monopole antenna of high permittivity is discussed in this project. Traditional dielectric resonator antennas provide advantages of low loss, compact and very low profile, which makes it a promising research topic recently. However, since the Q factor of dielectric resonators are usually very high, bandwidth of antennas is restricted. In this project, in order to enhance the bandwidth, a conducting strip is mounted on the dielectric material to excite the monopole rather than the dielectric materials. A 10 dB bandwidth of about 20 percent has been obtained which is much better than previous value obtained from the traditional dielectric resonator antenna.
