摘要
本文针对移动数字电视系统对天线的性能要求,创造性地将多层天线结构、分形缝隙天线、石墨烯导电墨水相结合,设计了一款用于移动数字电视的多层渐变分形缝隙石墨烯天线,制作了天线样品并测试了天线辐射特性。该款天线的中心频率为12.000 GHz,工作频带为10.026~14.938 GHz,绝对带宽为4.912GHz,相对带宽为39.35%,回波损耗最小值为?39.14 dB。该款天线完全覆盖了移动数字电视系统工作频段,是一款小尺寸、宽频带、集成化的移动数字电视天线,能够满足移动数字电视系统信号稳定、覆盖广泛、接收迅速、画面清晰、移动性强等要求。
According to the requirements of the mobile digital television system,the present paper creatively combines multilayer antenna structure,fractal slot antenna,and graphene conductive ink,designed a multilayer gradual fractal slot graphene antenna used for mobile digital television,fabricated the antenna sample and tested the radiation characteristics of the antenna.This antenna’s working center frequency is 12.000 GHz,the antenna’s working frequency range is 10.026~14.938 GHz,the antenna’s working bandwidth is 4.912 GHz,the antenna’s relative bandwidth is 39.35%,and the minimum value of return loss is?39.14 dB.This antenna completely covered the working frequency band of the mobile digital television system.It is a mobile digital television antenna that has small size,broadband,highly integrated,and can meet the requirements of mobile digital television system,such as stable signal,wide coverage,fast receiving,clear picture,strong mobility.
