Problems solved by technology

However, most plug-and-play digital TV receiving devices on the market use external receiving antennas. Such external receiving antennas must additionally require a connecting transmission line to connect the antenna to the plug-and-play digital TV receiving device. In addition to being inconvenient to carry, it will take up a lot of extra storage space and damage the appearance of the product, and the connection transmission line is often disconnected and used, and it is easy to cause poor contact of the internal transmission material

Embodiment Construction

[0030] figure 1 It is a structural diagram of an embodiment 101 of the antenna of the present invention. As shown in the figure, the antenna 101 of the present invention is a digital TV receiving antenna that can be installed in a plug-and-play device (plug-and-play device), including: a A radiating metal sheet (ie, the first conducting portion) 102, a meandering radiating metal arm (ie, the second conducting portion) 103, a flexible insulating portion (flexible insulating portion) 104, and a dielectric substrate 105, wherein The radiating metal sheet 102 and the meandering radiating metal arm 103 are a pair of resonant radiators. The radiating metal plate 102 is substantially a rectangular radiating metal plate, which is the system ground of the plug-and-play device. The meandering radiating metal arm 103 is electrically coupled to the radiating metal sheet 102 and has a flare angle or angle 301 with the radiating metal sheet 102 , and the resonance on the meandering radiati...

Abstract

The invention provides a digital television receiving antenna, which is applicable to a plug and play device. The digital television receiving antenna includes a first conductive part and a second conductive part which is coupled with the first conductive part and has a resonance route; wherein position of the second conductive part can be adjusted correspondingly to the first conductive part; an effective length of the resonance route is larger than a straight-line distance between two endpoints of the resonance route.

Description

technical field [0001] The present invention relates to an antenna, in particular to a digital TV receiving antenna suitable for a plug-and-play device. Background technique [0002] At present, there are three main sets of technical standards for digital terrestrial television broadcasting (Digital Television Broadcasting) in the world, namely: American standard ATSC (Advanced Television Systems Committee), European standard DVB-T (Digital Video Broadcasting-Terrestrial), Japanese ISDB-T (Terrestrial Integrated Services Digital Broadcasting). Compared with the traditional analog television broadcasting (AnalogTelevision Broadcasting) system using the NTSC (National Television Standard Committee) system, digital television broadcasting is a television system that converts television signals from "analog signals" to "digital signals". After digitizing the TV broadcast signal, some signal processing methods can be used to compress the digital signal before transmission, which...
