提出了一种基于3D打印技术的宽带多层倒截锥介质谐振器天线。它由三个截断的锥形介电环组成，有效介电常数从内到外递减。为了便于3D打印，利用中空立方体单胞重建了这种多层DR，并使用同轴SMA探头来激励这种具有多TM模式的DRA。通过将这些模式合并，可以获得60.8%(4.43-8.3 GHz)的测量10分贝阻抗带宽。此外，DR还安装在锯齿形地面上以获得稳定的已实现增益，1dB增益-波动带宽为55.3%(4.55-8.03 GHz)。
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).
