Wideband Dielectric Resonator Monopole Antenna

摘要

A wideband dielectric resonator monopole antenna, which includes a dielectric resonator and a monopole antenna, combines two frequency bands having close resonant frequencies to achieve 49% of bandwidth and omnidirectional radiation patterns within the frequency band. It includes a column structure and a substrate, wherein the surface of the column structure is coated with a conductive layer, the column structure is kept upright to the substrate, and the substrate is coated or printed with two slot lines extended inward from an edge of the substrate.
