Stacked Bow-Tie shaped dielectric resonators loaded monopole antenna

Abstract

Here, a new ‘Bow-Tie’ shaped dielectric resonators (DRs) loaded monopole antenna, obtained by splitting a conical piece of DR into four equal quarters, that offers 132% impedance bandwidth (covering 3.7–17.6 GHz) with uniform monopole like radiation pattern over the entire bandwidth, and 6 dBi peak gain has been proposed.
