T‐shaped dielectric resonator antenna with a high antenna gain

Abstract This Letter proposes a T‐shaped dielectric resonator (DR) antenna (DRA) to achieve a high antenna gain. The proposed antenna comprises a cylindrical DR top‐loaded by a cylindrical DR disk, forming a T‐shaped DRA that can be fabricated in one go. It is excited in the higher‐order HEM115 mode...

Description
Summary:Abstract This Letter proposes a T‐shaped dielectric resonator (DR) antenna (DRA) to achieve a high antenna gain. The proposed antenna comprises a cylindrical DR top‐loaded by a cylindrical DR disk, forming a T‐shaped DRA that can be fabricated in one go. It is excited in the higher‐order HEM115 mode. The DRA was designed in Ku band and fabricated to validate the idea. Its measured peak gain is 16.13 dBi at 13.34 GHz, with a 10‐dB impedance bandwidth of 9.36%. As compared with a conventional DRA, our design has a large gain enhancement of ∼9 dB.
