experiment example

[0138] Experimental example: Measurement of optical characteristics and signal loss based on the separation distance between dummy lines and antenna patterns

[0139]A metal (APC) grid structure with a width of 3 μm was formed on a Cyclo Olefin Polymer (COP) substrate with an area of ​​50 mm*50 mm. Cutting or patterning the above-mentioned mesh structure to divide the antenna pattern and the dummy line, while changing the distance between the above-mentioned dummy line and the above-mentioned antenna pattern after cutting, while changing the ratio to the width of the dummy line (D1 / D3, cf. image 3 ).

[0140] With 100 professional sensory testers as subjects, the visibility or non-visibility of the antenna pattern in the manufactured film antenna samples according to the variation of the D1 / D3 ratio was evaluated by visual observation. The number of testers judged to be visible in the observation results was counted, and the resultant values ​​are described in Table 1.

Abstract

A film antenna according to embodiments of the present invention includes: a dielectric layer; an antenna pattern which is disposed on the top surface of the dielectric layer and includes a mesh structure; and a dummy pattern which is disposed on the top surface of the dielectric layer and includes the same mesh structure as that of the antenna pattern. Optical characteristics can be enhanced through the identical structures of the antenna pattern and the dummy pattern.

Description

technical field [0001] The present invention relates to a film antenna and a display device including the same. More specifically, it relates to a film antenna including an electrode and a dielectric layer, and a display device including the same. Background technique [0002] In recent years, with the development of the information society, wireless communication technologies such as Wi-Fi and Bluetooth (Bluetooth) are combined with display devices to be presented in the form of, for example, smart phones. In this case, the antenna may be combined with the above-mentioned display device to implement the communication function. [0003] In recent years, as mobile communication technology advances, it is necessary to combine an antenna for performing ultra-high frequency band communication with the above-mentioned display device. In addition, in recent years, thin, highly transparent, and high-resolution display devices such as transparent displays and flexible displays hav...
