Embodiment approach

[0061] According to an exemplary embodiment, the signal pad 130 may be inserted into an entrance portion of the groove 150 . The signal pad 130 may be opposed to the connection bar 142 of the ground pad 140 in the first direction described above. The signal pad 130 is physically or electrically isolated from the ground pad 140 and may partially block the aforementioned entrance portion of the groove 150 .

[0062] In some implementations, substantially only the signal pad 130 enters the inside of the groove 150 , and the transmission line 125 does not extend into the groove 150 , and may be located outside the groove 150 .

[0063] As described above, the ground pad 140 has a recessed structure so that the periphery of the signal pad 130 can be effectively surrounded by the ground pad 140 . Accordingly, it is possible to more effectively shield transmission and reception signal noise around the signal pad 130 and electrical noise generated by the display device on which the a...

Embodiment 1

[0109] An antenna pattern including copper is formed on the COP dielectric layer. The dimensions of the antenna pattern in Embodiment 1 are as follows (refer to image 3 ).

[0110] Length of signal pad 130 (D3): 0.7mm

[0111] Width (W2) of signal pad 130: 10 μm / 50 μm / 100 μm / 200 μm

[0112] Length of transmission line 125: 2mm

[0113] Pattern width (W1) of ground pad: 1.1mm

[0114] Pattern width (W3) of ground pad: 10mm

[0115] Length of isolation space (D2): 980μm

Abstract

An antenna element of embodiments of the present invention comprises: a dielectric layer; a radiation pattern disposed on the top surface of the dielectric layer; a signal pad electrically connected to the radiation pattern; and a ground pad disposed to be spaced apart from the signal pad, and being recessed to have a spacing greater than length of the signal pad. Noise removing efficiency and radiation reliability can be improved through the ground pad.

Description

technical field [0001] The present invention relates to an antenna element and a display device including the same. More specifically, it relates to an antenna element including an electrode pattern and a display device including the antenna element. 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 communication function can be realized by combining the antenna with the above-mentioned display device. [0003] Recently, with the development of mobile communication technology, it is necessary to combine an antenna for ultra-high frequency band communication with the above-mentioned display device. [0004] For example, in the case of recent 5G high-band communication, signal transmission and reception may be interrupted due to shorter wavelengths, a...
