摘要

A wideband multilayered inverted truncated conical dielectric resonator antenna (ITCDRA) based on 3D-printing technology is proposed. It comprises three truncated conical dielectric rings with decreasing effective dielectric constants from inside to outside. To facilitate the 3D-printing, hollow cube unit cells are utilized to reconstruct this multilayered DR. A coaxial SMA probe is used to excite this DRA with multiple TM modes. By merging these modes, a measured -10-dB impedance bandwidth of 60.8% (4.43-8.3 GHz) can be obtained. Besides, the DR is mounted on a serrated ground to obtain stable realized gain with the measured 1-dB gain-fluctuation bandwidth of 55.3% (4.55-8.03 GHz).
