For example, the antenna element may be provided as a vertical radiation antenna through the ground electrode layer 110.

2 is a schematic plan view illustrating a structure of an antenna electrode layer according to example embodiments. FIG. 3 is a partially enlarged plan view of area A of FIG. 2.

Referring to FIG. 2, the antenna electrode layer 120 may include an antenna pattern including a radiation electrode 130 and a transmission line 131. The antenna pattern or antenna electrode layer 120 may further include a pad electrode 140 connected to an end of the transmission line 131. The antenna electrode layer 120 may include a dummy mesh 135 arranged around the antenna pattern.

The antenna electrode layer 120 is silver (Ag), gold (Au), copper (Cu), aluminum (Al), platinum (Pt), palladium (Pd), chromium (Cr), titanium (Ti), tungsten (W). , Niobium (Nb), tantalum (Ta), vanadium (V), iron (Fe), manganese (Mn), cobalt (Co), nickel (Ni), zinc (Zn), or an alloy thereof. . These may be used alone or in combination of two or more. For example, the radiation electrode 130 may include silver (Ag) or a silver alloy in order to implement low resistance, and for example, may include a silver-palladium-copper (APC) alloy.

In some embodiments, the antenna electrode layer 120 may include a transparent metal oxide such as indium tin oxide (ITO), indium zinc oxide (IZO), indium zinc tin oxide (ITZO), and zinc oxide (ZnOx). . For example, the antenna electrode layer 120 may have a multilayer structure including at least one metal or alloy layer and a transparent metal oxide layer.

According to example embodiments, the antenna electrode layer 120 may include a mesh structure. Accordingly, the transmittance of the radiation electrode 130 may be increased, and the flexibility of the antenna element may be improved. Therefore, the antenna element can be effectively applied to a flexible display device.

The transmission line 131 may extend from one end of the radiation electrode 130 to be electrically connected to the signal pad 142. For example, the transmission line 131 may protrude from the center of the radiation electrode 130 and extend.

In one embodiment, the transmission line 131 includes substantially the same conductive material as the radiation electrode 130 and may be formed through a substantially same etching process. In this case, the transmission line 131 may be integrally connected with the radiation electrode 130 to be provided as a substantially single member, and may include substantially the same mesh structure.

The pad electrode 140 may include a signal pad 142 and a ground pad 144. The signal pad 142 may be electrically connected to the radiation electrode 130 through the transmission line 131, and may electrically connect the driving circuit unit (eg, an IC chip) and the radiation electrode 130.

For example, a circuit board such as a flexible circuit board (FPCB) may be bonded to the signal pad 142, and the driving circuit unit may be disposed on the flexible circuit board. Accordingly, signal transmission/reception may be implemented between the antenna pattern and the driving circuit unit.

In some embodiments, a pair of ground pads 144 may be electrically and physically spaced apart from the signal pad 142 with the signal pad 142 interposed therebetween to face each other. Accordingly, vertical radiation and horizontal radiation may be implemented through the antenna element.

The width of the separation region 132 is not particularly limited and may be 0.5 μm or more. Accordingly, signal interference that may occur when the dummy mesh 135 and the radiation electrode 130 are formed too close to each other can be prevented.

In an embodiment, while employing the mesh structure, the electrode line included in the mesh structure is formed of a low-resistance metal such as copper, silver, or APC alloy, thereby suppressing an increase in resistance. Therefore, it is possible to effectively implement a low-resistance, high-sensitivity transparent film antenna.

According to example embodiments, at least one segmented region 138 may be included in each unit cell. In some embodiments, at least one segmented region 138 may be formed for each of the first electrode line 136 and the second electrode line 137 divided into the unit cells. In this case, it is possible to prevent the generation of parasitic capacitance due to the connected metal mesh pattern, thereby reducing signal interference that occurs when the antenna element is disposed above or below the touch sensor.

According to some embodiments, at least one segmented region 138 may be formed around an intersection of the first electrode line 136 and the second electrode line 137. Accordingly, noise that may be concentrated between the intersecting unit cells can be more effectively suppressed.

The segmented regions 138 formed in the dummy mesh 135 may be irregularly distributed. In this case, it is possible to reduce the visibility by more suppressing the moiré phenomenon caused by the overlapping of regular patterns.

According to some embodiments, a distance between adjacent segmented regions 138 included in the first electrode line 136 or the second electrode line 137 may be smaller than the length of one side of each unit cell. The length between the segmented regions 138 is not particularly limited, and may be 0.5 to 5 μm in consideration of the size of the unit cell. When the length between the segmented regions 138 is smaller than the length of one side of the unit cell, more segmented regions 138 may be formed in the unit cell, and thus parasitic capacitance that may occur due to the dummy mesh 135 Signal interference can be prevented by more suppressing.
