Abstract
According to the performance requirements of the mobile digital TV system, the present paper originally combines polygonal four helix antenna, induction array antenna, dielectric constant gradient film, graphene conductive ink and nano silver conductive ink, designed a mobile digital TV inductive array four helix antenna. The result of test indicates that this antenna has completely covered the frequency band of the mobile digital TV system. This antenna has strong corrosion resistance and damage resistance, stable physical and mechanical performance and radiation performance, small size, thin thickness and large working bandwidth, so it has broad application prospects.
