Disclosed herein is a bandwidth adjustable dielectric resonant antenna. The dielectric resonator antenna includes: a multi-layer substrate; a first conductor plate formed on a top portion of an uppermost insulating layer to have an opening part; a second conductor plate formed on a bottom portion of a lowermost insulating layer; a plurality of metal vial holes penetrating through a circumference of the opening part of the first conductor plate at a predetermined interval; a feeding unit supplying power to the dielectric resonator embedded in the multi-layer substrate in the cavity shape by the first conductor plate, the second to conductor plate, and the plurality of metal via holes; and at least one multi-resonant generation via holes formed within the dielectric resonator so as to adjust the bandwidth by generating the multi-resonance within the dielectric resonator, thereby improving the bandwidth without increasing the size of the dielectric resonator and implementing miniaturization. |
