AI Technical Summary

Problems solved by technology

In the case of forming an interconnect structure, the thickness of the antenna increases and may cause mutual interference and noise with other pixel structures or sensing structures in the display device
[0006] For example, Korean Laid-Open Patent No. 2003-0095557 discloses an antenna structure installed in a portable terminal, but does not provide a solution to the above-mentioned problems

Abstract

An antenna element of embodiments of the present invention comprises: a dielectric layer; a first electrode layer disposed on an upper surface of the dielectric layer and including a radiation pattern; a second electrode layer disposed on a bottom surface of the dielectric layer; and a flexible circuit board connecting the first electrode layer and the second electrode layer to each other throughthe side of the dielectric layer. It is possible to improve the grounding and noise removal efficiency through the flexible circuit board.

Description

technical field [0001] The present invention relates to an antenna element and a display device comprising it. More specifically, the present invention relates to an antenna element including an electrode and a dielectric layer and a display device including the antenna element. Background technique [0002] With the development of information technology, for example, wireless communication technologies such as Wi-Fi and Bluetooth are combined with display devices in the configuration of smart phones. In this case, the antenna can be combined with the display device to provide a communication function. [0003] Due to the rapid development of mobile communication technology, an antenna capable of realizing UHF communication equivalent to 3G to 5G is required in the display device. [0004] In addition, since the display device on which the antenna is mounted becomes thinner, the space for the antenna is also reduced. Therefore, the antenna will be adjacent to various cond...
