The Multilayer Gradual Fractal Slot Graphene Antenna Used for Mobile Digital Television
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4.912 GHz，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。
Abstract: 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, de-signed a multilayer gradual fractal slot graphene antenna used for mobile digital television, fabri-cated 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 tele-vision system, such as stable signal, wide coverage, fast receiving, clear picture, strong mobility.
