Thin digital video antenna

The present invention relates to a digital video antenna, and more particularly to a thin digital video antenna for transmitting digital video information and having the characteristics of being thin, convenient, and not occupying space.

In 1925, Scottish electrical engineer John Logie Baird showed off his first semi-mechanical analog TV set in London, and during the 1936 Berlin Olympics, a newly developed TV camera was used to transmit black and white audio and video information to the TV set for live broadcast. The world has been deeply impressed by the TV. With the vigorous development of televisions, cameras, TV programs and movies after the end of the Second World War, TVs have become a necessity in every family. For the early analog TVs, the sharpness of the image is related to the intensity of the wireless signal transmitting the audio and video information, and the audio and video information can be transmitted in the form of amplitude modulation or frequency modulation, respectively.
