[0085] To make the objectives, features, and advantages of the present invention more obvious and understandable, specific embodiments of the present invention are hereinafter given, and in conjunction with the accompanying drawings, the detailed description is as follows.

[0086] In the specification and claims, certain terms are used to refer to specific elements. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same element. The specification and claims do not use the difference in names as a way to distinguish elements, but use the difference in the functions of elements as the criterion for distinction. The terms "comprising" and "including" mentioned throughout the specification and claims are open-ended terms and should be interpreted as "including but not limited to". The term "substantially" means within an acceptable error range, and those skilled in the art can solve the technical problem within a certain error range and achieve the basic technical effect. In addition, the term "coupled" in this specification includes any direct and indirect electrical connection means, where the electrical connection is a capacitive connection or an inductive connection. Therefore, if it is described in the text that a first device is coupled to a second device, it means that the first device can be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

[0087] The following disclosure provides many different embodiments or examples for implementing different features of the present case. The following disclosure describes specific examples of each component and its arrangement to simplify the description. Of course, these specific examples are not intended to be limiting. For example, if the specification describes that a first feature is formed on or above a second feature, it means that it may include an embodiment in which the first feature and the second feature are in direct contact, and may also include an embodiment in which additional features are formed between the first feature and the second feature, so that the first feature and the second feature may not be in direct contact. In addition, the same reference symbols or (and) marks may be reused in different examples in the following specification. These repetitions are for the purpose of simplification and clarity, and are not intended to limit a specific relationship between the different embodiments or (and) structures discussed.

[0088] In addition, there are terms related to space. For example, "below", "beneath", "lower", "above", "higher" and similar terms are used to facilitate the description of the relationship between an element or feature and another (some) element or feature in the drawings. Except for the orientation shown in the drawings, these space-related terms are intended to include different orientations of the device during use or operation. The device may be turned to different orientations (rotated 90 degrees or other orientations), and the space-related terms used here can also be interpreted in the same way.

[0089] Figure 1 Shows a top view of the communication device 100 according to an embodiment of the present invention. For example, the communication device 100 can be applied in a signal transmission environment, but is not limited thereto. In Figure 1In an embodiment, the communication device 100 includes at least one sheet structure 110. It must be understood that although not shown in Figure 1 , the communication device 100 may further include other components, such as a non-conductive housing, a controller, and / or a power supply module.

[0090] As Figure 1 shown, the sheet structure 110 includes a plurality of metal units 120-1, 120-2,..., 120-N and a plurality of interconnection units 130-1, 130-2,..., 130-M, where "N" and "M" may each be a positive integer greater than or equal to 4. The plurality of interconnection units 130-1, 130-2,..., 130-M are coupled to the plurality of metal units 120-1, 120-2,..., 120-N and are arranged alternately with the plurality of metal units 120-1, 120-2,..., 120-N. For example, each metal unit can be coupled to four adjacent interconnection units, and each interconnection unit can be coupled to four adjacent metal units, but it is not limited thereto. The plurality of interconnection units 130-1, 130-2,..., 130-M can also be controlled according to a plurality of control signals SC-1, SC-2,..., SC-M. In some embodiments, the plurality of SC-1, SC-2,..., SC-M can be generated by a controller and can be used to adjust the operating characteristics of the plurality of interconnection units 130-1, 130-2,..., 130-M.

[0091] In some embodiments, the sheet structure 110 has an operational frequency band, which can be between 30 GHz and 300 GHz. Therefore, the communication device 100 can at least support broadband operation of millimeter wave (mmWave).

[0092] In some embodiments, the sheet structure 110 can be further divided into a first region 140 and a second region 150, where the second region 150 can be different from the first region 140. It must be understood that the shapes and sizes of the first region 140 and the second region 150 are not particularly limited in the present invention. In other embodiments, the sheet structure 110 can be further divided into more regions.

[0093] Figure 2 A side view of the communication device 100 according to an embodiment of the present invention is shown. InFigure 2 In an embodiment, a first region 140 of the sheet-like structure 110 has a first normal line 145. In response to a first incident wave WI1, the sheet-like structure 110 can generate a first reflection wave WR1 and a first transmission wave WT1. Specifically, when the first region 140 of the sheet-like structure 110 receives the first incident wave WI1, the first region 140 of the sheet-like structure 110 will correspondingly output the first reflection wave WR1 and the first transmission wave WT1. With respect to the first normal line 145, the first incident wave WI1 can have a first incident angle θI1, the first reflection wave WR1 can have a first reflection angle θR1, and the first transmission wave WT1 can have a first transmission angle θT1. On the other hand, a first reflection ratio KA of the first reflection wave WR1 and a first transmission ratio KB of the first transmission wave WT1 can be defined according to the following equations (1), (2), and (3):

[0094]

[0095]

[0096] KA + KB ≤ 1…………………………………………(3)

[0097] Where "KA" represents the first reflection ratio KA, "KB" represents the first transmission ratio KB, "WI1" represents the radiation energy of the first incident wave WI1, "WR1" represents the radiation energy of the first reflection wave WR1, and "WT1" represents the radiation energy of the first transmission wave WT1.

[0098] Because the sheet-like structure 110 usually has non-ideal losses, the sum of the first reflection ratio KA and the first transmission ratio KB will be less than or equal to 1. It should be noted that both the first reflection ratio KA and the first reflection angle θR1 of the first reflection wave WR1 can be adjusted according to the plurality of control signals SC-1, SC-2, …, SC-M. In addition, both the first transmission ratio KB and the first transmission angle θT1 of the first transmission wave WT1 can also be adjusted according to the plurality of control signals SC-1, SC-2, …, SC-M.

[0099] Figure 3 Shows a side view of the communication device 100 according to an embodiment of the present invention. In Figure 3In an embodiment, a second region 150 of the sheet structure 110 has a second normal 155. In response to a second incident wave WI2, the sheet structure 110 can generate a second reflected wave WR2 and a second transmitted wave WT2. Specifically, when the second region 150 of the sheet structure 110 receives the second incident wave WI2, the second region 150 of the sheet structure 110 will correspondingly output the second reflected wave WR2 and the second transmitted wave WT2. With respect to the second normal 155, the second incident wave WI2 can have a second incident angle θI2, the second reflected wave WR2 can have a second reflection angle θR2, and the second transmitted wave WT2 can have a second transmission angle θT2. On the other hand, a second reflection ratio KC of the second reflected wave WR2 and a second transmission ratio KD of the second transmitted wave WT2 can be defined according to the following equations (4), (5), (6):

[0100]

[0101]

[0102] KC + KD ≤ 1…………………………………………(6)

[0103] Where "KC" represents the second reflection ratio KC, "KD" represents the second transmission ratio KD, "WI2" represents the radiation energy of the second incident wave WI2, "WR2" represents the radiation energy of the second reflected wave WR2, and "WT2" represents the radiation energy of the second transmitted wave WT2.

[0104] Because the sheet structure 110 usually has non-ideal losses, the sum of the second reflection ratio KC and the second transmission ratio KD will be less than or equal to 1. It should be noted that both the second reflection ratio KC and the second reflection angle θR2 of the second reflected wave WR2 can be adjusted according to the plurality of control signals SC-1, SC-2, …, SC-M. In addition, both the second transmission ratio KD and the second transmission angle θT2 of the second transmitted wave WT2 can also be adjusted according to the plurality of control signals SC-1, SC-2, …, SC-M.

[0105] Under the design proposed in the present invention, by using the sheet structure 110, the radiation characteristics of the reflected wave and the transmitted wave of the communication device 100 can be appropriately adjusted. In addition, since the sheet structure 110 can be divided into multiple regions, it can also simultaneously process incident waves from various directions. Generally speaking, the communication device 100 of the present invention can be used to replace a traditional active base station and can maintain good high-frequency signal transmission quality.

[0106] In some other embodiments, the sheet structure 110 of the communication device 100 can also be modified into a three-dimensional structure, such that the multiple metal units 120-1, 120-2, …, 120-N and the multiple interconnecting units 130-1, 130-2, …, 130-M can be stacked three-dimensionally with each other, and similar effects can also be achieved.

[0107] The following embodiments will introduce various different configurations and detailed structural features of the communication device 100. It must be understood that these drawings and descriptions are for illustrative purposes only and are not used to limit the present invention.
