The present invention relates to a light transmission radiating element device for VHF to UHF, and in particular to a film structure with transparent and conductive properties, which can be integrated on a transparent substrate such as a glass curtain, Hide its body and meet the aesthetic design requirements.

In recent years, as digital TVs combine various portable electronic products, such as mobile phones, personal digital assistants (PDAs), notebook computers, etc., the use of miniaturized antennas in these portable electronic products has become a trend. However, for antennas that are generally used to receive digital TV signals, signals from Very High Frequency (VHF) to Ultra High Frequency (UHF) bands are used. Because the antenna size corresponds to the wavelength, Therefore, the antenna size is usually larger. In addition, conventional antennas are designed with metal, and for large-scale digital TV antennas, they cannot be integrated on vehicles such as home furnishings or glass, because they cannot meet aesthetic design requirements. If a transparent conductive material (such as a transparent conductive film) can be used to make the planar antenna, it can be placed on a glass curtain or It is on any object, and hides the existence of the antenna, so as to meet the aesthetic design requirements. On the other hand, the conventional transparent conductive elements are made of transparent conductive films.
