基于石墨烯的轨道角动量微带阵列天线设计
Orbital angular momentum microstrip array antenna design based on graphene
摘要
Abstract
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.关键词
