摘要
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 similar to 9 dB.
