Problems solved by technology

[0004] For example, in the case of using a transparent conductive oxide electrode such as an ITO electrode to apply an antenna structure to a display device, although transmittance can be improved, signal loss may be caused due to increased resistance.
In the case of adjusting the dielectric constant of the dielectric layer to receive high-frequency band signals, the thickness of the region for inserting the antenna structure may be excessively increased, and it may be difficult to adjust the thickness of the dielectric layer independently of the antenna electrodes and / or the display device
[0005] In addition, as display devices become lighter and thinner, the thickness and volume of antenna structures are also reduced, and in this case, electrode sensitivity and resistance may be degraded

Embodiment Construction

[0041] According to an exemplary embodiment of the present invention, there is provided a film antenna including a first electrode layer, a dielectric layer disposed on the first electrode layer, and a second electrode layer disposed on the dielectric layer . The dielectric layer may have a thickness to sense and receive a signal of a high frequency band within a predetermined dielectric constant range.

[0042] The film antenna may be, for example, a microstrip patch antenna manufactured in the form of a transparent film. The film antenna can be applied to, for example, a communication device for 3G to 5G mobile communication. For example, a film antenna may be driven in a high frequency band of about 10 GHz (in one embodiment, a range from about 25 GHz to 35 GHz).

[0043] Furthermore, an embodiment of the invention provides a display device including the film antenna.

[0044] Hereinafter, embodiments of the present invention will be described in more detail with referen...

Abstract

A film antenna according to embodiments of the present invention comprises: a first electrode layer; a dielectric layer disposed on the first electrode layer and having a thickness of 50 to 1000[mu]mand a dielectric permittivity of 2 to 10; and a second electrode layer disposed on the dielectric layer. The high-frequency driving characteristics of the film antenna can be improved by controlling the dielectric permittivity and thickness of the dielectric layer.

Description

technical field [0001] The present invention relates to a film antenna and a display device including the film antenna. More particularly, the present invention relates to a film antenna including an electrode and a dielectric layer and a display device including the same. Background technique [0002] With the development of the information society, wireless communication technologies such as Wi-Fi, Bluetooth, etc. are combined with display devices in the form of, for example, smart phones. In this case, the antenna may be combined with the display device to perform a communication function. [0003] With the recent development of mobile communication technology, it is necessary to incorporate an antenna for performing communication of a super high frequency band above 3G into a display device. Furthermore, as thin, high-transparency, high-resolution display devices such as transparent display devices, flexible display devices, etc. have recently been developed, there is ...
