Abstract

A film antenna-circuit connection structure according to embodiments of the present invention comprises: a film antenna including radiation patterns and pads; and a circuit board which is electricallyconnected with the film antenna and which includes connection wirings electrically connected with each pad of the film antenna, and a dummy barrier arranged between neighboring connection wirings. Noise and interference between the connection wirings can be blocked through the dummy barrier.

Description

technical field [0001] The present invention relates to a film antenna circuit connection structure and a display device including the structure. More specifically, it relates to a film antenna circuit connection structure including a plurality of connection wirings, and a display device including the structure. Background technique [0002] In recent years, with the development of the information society, wireless communication technologies such as Wi-Fi and Bluetooth (registered trademark) are combined with display devices, for example, in the form of smart phones. In this case, the antenna is combined with the above-mentioned display device and can perform a communication function. [0003] Recently, as mobile communication technology advances, it is necessary to combine an antenna for communication in the ultra-high frequency band with the above-mentioned display device. [0004] For example, an adjustment circuit is required to drive the radiation pattern of an integr...
