Claim 14:
15. A method of fabricating a dielectric resonator, comprising the steps:
a) providing a substrate-integrated dielectric resonator, which comprises:
i) providing a first substrate layer with a first dielectric constant;
ii) forming a plurality of first vias on the first substrate layer; each said first vias having a via-hole extending through the first substrate layer, and a first dielectric material with a second dielectric constant contained within the first via-hole; and
iii controlling a resonator mode of the substrate-integrated dielectric resonator by forming a plurality of second vias in the substrate-integrated dielectric resonator; each said second via having a second via-hole extending through the first substrate layer and filled with a second dielectric material of a third dielectric constant;

b) providing a third substrate layer arranged on one side of a first substrate layer of the substrate-integrated dielectric resonator; the third substrate layer further comprising a first microstrip feedline and an antenna ground plane;
c) providing a second substrate layer interposed between the first substrate layer and the third substrate layer; the second substrate layer further comprising a second microstrip feedline; the first microstrip feedline and the second microstrip feedline configured as two feeding ports of the dielectric resonator antenna; wherein the second microstrip feedline is configured with a plurality of first dielectric vias therethrough.
