摘要

提出了一种毫米波介质谐振器天线的设计方法。在天线设计中采用电磁带隙(EBG)结构来提高天线的特性。计算了所设计天线在有EBG和没有EBG的情况下的仿真结果，给出了阻抗带宽、反射系数和增益等参数。引入周期单元结构(EBG)后，天线的参数得到了改善。采用EBG结构和不采用EBG结构的天线的反射系数分别为- 30.5 dB和- 20.8 dB。在有EBG结构时，天线的峰值增益为25 dBi，高于无EBG结构时的峰值增益(8 dBi)。设计的天线谐振频率为33 GHz，阻抗带宽为700 MHz。利用Ansys HFSS软件对天线进行了设计和仿真。

An Electromagnetic Band Gap Structure Based Dielectric Resonator Antenna for Millimeter-Wave Applications

This paper presents a design of a dielectric resonator antenna (DRA) for millimeter-wave applications. An electromagnetic band gap (EBG) structure is used in the antenna design to enhance the antenna characteristics. The simulated with and without EBG results of the designed antenna is calculated to show the parameters such as impedance bandwidth, reflection coefficient, and gain. The parameters of the proposed antenna have improved after the periodic unit cell structure (EBG) introduction. The obtained reflection coefficients of the proposed antenna with and without EBG structure are −30.5 dB and −20.8 dB, respectively. In the presence of an EBG structure antenna shows a peak gain of 25 dBi, which is higher than the without EBG (8 dBi) structure. The designed antenna resonates at 33 GHz with an impedance bandwidth of 700 MHz. The Ansys HFSS software is used to design and simulate the proposed antenna.
