Claim 0:
1. A dielectric resonator antenna, comprising:
a) a substrate-integrated dielectric resonator, which comprises
i) a first substrate layer with a first dielectric constant;
ii) a plurality of first vias each having a first 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) a plurality of second vias each having a second via-hole extending through the first substrate layer and filled with a second dielectric material with a third dielectric constant;

b) 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
i) a first microstrip feedline; and
ii) an antenna ground plane;

c) 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.
