Abstract:
According to the requirements of the mobile digital television system, the present paper creatively combines growth tree fractal dipole antenna, rectangular antenna array, Polyethylene Terephthalate (PET) thin film substrate, and graphene conductive ink, designed an array fractal graphene antenna used for mobile digital television, fabricated the antenna sample and tested the radiation characteristics of the antenna. The result of test indicate that the antenna's working frequency range is 10.841-14.136 GHz, the antenna's working bandwidth is 3.295 GHz, the antenna's relative bandwidth is 26.38%, the minimum value of return loss is -32.45 dB. This antenna completely covered the working frequency band of the mobile digital television system, it is a mobile digital television antenna that have 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.
