Orbital angular momentum microstrip array antenna design based on graphene
针对目前大部分轨道角动量天线所存在的生成模态数量少、回波损耗差等问题,设计了一种太赫兹频段使用石墨烯的多模态轨道角动量微带阵列天线.给出了轨道角动量(OAM)天线的结构设计、材料和尺寸,并对尺寸进行了优化.分析了石墨烯材料对天线性能的影响.使用CST软件对石墨烯OAM微带阵列天线性能进行仿真.结果表明:所设计的天线通过调整馈电相位,能产生0-4模态的涡旋波,天线的中心频率为3.700 THz,S11达到-63.00 dB,阻抗带宽为0.958 THz,增益达9.70 dBi,可见具有较好的性能.新设计为多模态太赫兹涡旋波的有效产生和控制提供了可行的途径.
To solve the problems of most current orbital angular momentum(OAM)antennas with few generated modes and poor return loss,the multi-mode OAM microstrip array antenna using graphene in the terahertz frequency band was designed.The structure,material and dimension of OAM antenna were given,and the dimension was optimized.The effect of graphene on antenna performance was analyzed.The performance of graphene OAM antenna was simulated in CST.The results show that by simply adjusting the feeding phase,the vortex waves of 0-4 modes can be generated with center frequency of 3.700 THz,Sn of-63.00 dB,impedance bandwidth of 0.958 THz and gain up to 9.70 dBi.The excellent performance provides viable approach to the effective generation and control of multi-mode terahertz vortex waves.
