Antenna with via fence

1. An antenna, comprising:

a dielectric resonator surrounded by a first via fence for interrupting leakage of signals within a multilayered substrate;

a patch antenna formed on an opening surface of the dielectric resonator;

a coupling aperture formed on an internal ground surface within the multilayered substrate; and

a feeding line for transferring a signal applied from the outside;

wherein the feeding line is surrounded by a second via fence for interrupting leakage of signals.

2. The antenna of claim 1 , wherein the dielectric resonator is formed within the multilayered substrate by using the via fence, and the via fence suppresses leakage of a signal through the multilayered substrate.

3. The antenna of claim 1 , wherein the via fence includes a plurality of via walls surrounding the dielectric resonator.

4. The antenna of claim 1 , wherein a size and thickness of the dielectric resonator is determined to resonate at an in-use frequency band.

5. The antenna of claim 1 , wherein a bandwidth of the antenna is expanded by a coupling through the coupling aperture between the dielectric resonator and the feeding line.

6. The antenna of claim 1 , wherein the antenna enhances a gain by using the additional patch.

7. The antenna of claim 1 , wherein the feeding line has a form of a strip line.

8. The antenna of claim 1 , wherein the antenna regulates directions of the coupling aperture and the feeding line to regulate antenna polarization.

9. The antenna of claim 1 , wherein the multilayered substrate comprises a plurality of upper antenna layers disposed on a plurality of lower feeding network layers.

10. The antenna of claim 9 , wherein the internal ground surface is disposed between the plurality of upper antenna layers and the plurality of lower feeding network layers.

11. The antenna of claim 10 , wherein the feeding line is disposed on a layer of the plurality of lower feeding network layers and substantially aligned with the coupling aperture.
