HIGH GAIN DIELECTRIC RESONATOR ANTENNA ARRAY FOR 5.8 GHZ APPLICATIONS

摘要

The present invention provides a dielectric resonator antenna for 5.8 GHz wireless communications. In one embodiment, the dielectric resonator antenna comprises a duroid substrate made from dielectric material, a microstrip line embedded in the substrate with slots, where the microstrip line is made from electrically conductive material, a SMA connector electrically coupled with one end of the microstrip line, and a plurality of dielectric resonators coupled with the microstrip line via the slots, wherein the microstrip line is configured in such a way that it goes through all the surface of the dielectric substrate so that the plurality of dielectric resonators form a condensed array format on the surface of the dielectric substrate, resulting a miniaturized dielectric resonator antenna. The present invention also provides a process for design and fabrication of the dielectric resonator antenna.
