摘要

提出了一种减少介质杆天线三次谐波信号意外发送和接收的新概念。为了抑制三次谐波辐射，在介质杆天线中使用了加性制造的光子带隙材料。该天线设计工作频率为5ghz，并在三次谐波频率15ghz处显示带隙。材料的设计通过带隙材料的能带图和由于考虑增材制造（AM）工艺而引入的缺陷来解释。通过对有和无谐波抑制的矩形波导馈电介质杆天线样机进行数值模拟，验证了其工作原理。实验验证了所提出的设计方案。该天线的输入反射系数和远场辐射特性对其进行了表征。实验结果与仿真结果吻合较好，证实了天线的三次谐波抑制能力。

Dielectric Rod Antenna With Third-Harmonic Suppression via Photonic Crystal Bandgap Material

A novel concept to mitigate the unintended transmission and reception of signals at the third harmonic of dielectric rod antennas is proposed. To suppress the third-harmonic radiation, an additive-manufactured photonic bandgap material is used in the dielectric rod antenna. The antenna has been designed to operate at the frequency of 5 GHz and exhibit a bandgap at the third-harmonic frequency of 15 GHz. The design of the material is explained via the band diagram of the bandgap material and imperfections introduced due to the additive manufacturing (AM) process considered. Numerical simulations of dielectric rod antenna prototypes fed via a rectangular waveguide (RWG) with and without harmonic suppression are carried out to confirm the operational principle. The design proposed is verified experimentally. The manufactured antenna is characterized in terms of its input reflection coefficient and far-field radiation properties. The obtained experimental results agree well with predictions obtained through simulations and confirm the third-harmonic suppression capability of the antenna.
