Description

Technical Field

[0001] This invention relates to an antenna structure, and more particularly to a wideband antenna structure. Background Technology

[0002] Driven by the pursuit of convenience, humanity has generated a massive demand for connected devices. Consequently, wireless communication systems are evolving towards higher transmission rates and throughput. For example, simply increasing the utilization of 2.4GHz and 5GHz channels in Wi-Fi 6 is insufficient to keep up with the rapid growth in the number of connected devices. Therefore, Wi-Fi 6E added a 6GHz band to address channel congestion by increasing the number of channels. However, widening or increasing the communication bandwidth of wireless communication systems also means a corresponding increase in the design complexity and cost of the radio frequency front-end (RF front-end) unit. Therefore, how to reduce the design complexity and cost of the RF front-end unit in next-generation wireless communication systems has become a key issue in the market, with antenna structure design being particularly relevant.

[0003] In view of this, there is an urgent need in the market for an antenna structure that can not only meet the needs of wireless communication systems to widen or increase the communication bandwidth, but also effectively reduce the design complexity and cost of radio frequency front-end units. Summary of the Invention

[0004] The present invention provides an antenna structure that couples a radiating part and a connecting part through a cooperating part, wherein the cooperating part and the radiating part are separated from each other, and the cooperating part and the connecting part are separated from each other, which helps to widen the operating frequency band of the antenna structure and further effectively reduce the design complexity and cost of the radio frequency front-end unit.

[0005] According to one embodiment of the present invention, an antenna structure is provided, comprising a radiating portion, a grounding portion, a connecting portion, and a cooperating portion. The connecting portion is electrically connected between the radiating portion and the grounding portion, and provides a feed port for feeding signals into the antenna structure. The cooperating portion is electrically connected to the grounding portion, couples the radiating portion and the connecting portion, and is separate from both the radiating portion and the connecting portion. This helps to widen the operating bandwidth of the antenna structure.

[0006] According to another embodiment of the present invention, an antenna structure is provided, comprising a radiating part, a grounding part, a connecting part, and a cooperating part. The radiating part includes one or more radiating regions. The connecting part is electrically connected between the radiating part and the grounding part, and the connecting part is provided with a feed port to feed signals to the antenna structure. The cooperating part is electrically connected to the grounding part. Each of the radiating part, the grounding part, the connecting part, and the cooperating part is made of metal. Each of the connecting part and the cooperating part is plate-shaped with its normal direction parallel to a second direction. At least a portion of the grounding part and each of the radiating parts are plate-shaped with their normal direction parallel to a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. Therefore, the three-dimensional antenna structure helps to meet the application requirements of wider bandwidths or new bandwidths without increasing the number of antennas or the layout volume.

[0042] Embodiments of the present invention will now be described with reference to the accompanying drawings. For clarity, many practical details will be set forth in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, these practical details are not essential in the embodiments of the present invention. Furthermore, for the sake of simplicity in the drawings, some well-known and customary structures and elements will be illustrated in a simple schematic manner; and repeated elements may be denoted by the same reference numerals.

[0043] Figure 1 A perspective view of an antenna structure 100 according to an embodiment of the present invention is shown. Figure 2 Draw Figure 1 A perspective view of the antenna structure 100 in the embodiment from another angle. Please refer to... Figure 1 and Figure 2 The antenna structure 100 includes a radiating section 130, a grounding section 140, a connecting section 150, and a cooperating section 160. The connecting section 150 is electrically connected between the radiating section 130 and the grounding section 140, and provides a feed port 170 to feed signals to the antenna structure 100 (it should be understood that the feed port 170 can also be used to receive signals transmitted from the antenna structure 100). The cooperating section 160 is electrically connected to the grounding section 140. Furthermore, the "connection" described in this invention refers to a physical connection between two elements, which can be direct or indirect. The "coupled" described in this invention refers to two elements that are separated from each other without a physical connection, but rather the electric field energy generated by the current in one element excites the electric field energy of the other element.

[0044] In detail, the cooperating part 160 can couple the radiating part 130 and the connecting part 150, and the cooperating part 160 and the radiating part 130 are separate from each other, as are the cooperating part 160 and the connecting part 150. In this way, by increasing the path of the antenna metal radiator through the cooperating part 160, and through the mutual coupling between the paths, the operating bandwidth of the antenna structure 100 (e.g., the voltage standing wave ratio (VSWR) at the corresponding frequency, which is less than or equal to 2) is contributed not only by the radiating part 130, but also by the cooperating part 160 coupling the radiating part 130 and the connecting part 150, thereby widening or increasing the operating bandwidth of the antenna structure 100, and further effectively reducing the number of antennas used in wireless broadband communication products. For example, the antenna structure 100 can be applied to the radio frequency front-end unit of a WIFI 6E system. The radiating part 130 provides an operating frequency band of about 2.4 GHz (e.g., 2.4 GHz to 2.5 GHz) and about 5 GHz (e.g., 5.15 GHz to 5.85 GHz). The cooperating part 160 couples the radiating part 130 and the connecting part 150 to extend the operating frequency band from about 5 GHz to about 6 GHz (e.g., 5.85 GHz to 7.125 GHz). That is, it provides an operating frequency band of 2.4 GHz to 2.5 GHz and 5.15 GHz to 7.125 GHz that meets the requirements of the WIFI 6E standard, thereby meeting the application requirements of the WIFI 6E system with increased channels without increasing the number of antennas and the layout volume.

[0045] Figure 3 Draw Figure 1 Side view of antenna structure 100 in the embodiment. Figure 4 Draw Figure 1 Front view of antenna structure 100 in the embodiment. Figure 5 Draw Figure 1 A top view of antenna structure 100, which should be understandable. Figures 3 to 5 The side view, front view, and top view described herein can be swapped or adjusted as needed, without limiting the assembly orientation of the antenna structure 100. Please refer to... Figures 1 to 5 The radiating section 130 may include one or more radiating regions. In this embodiment, the radiating section 130 includes two radiating regions, namely a first radiating region 131 and a second radiating region 132. The first radiating region 131 and the second radiating region 132 are arranged along a first direction x and are directly electrically connected. The lengths of the first radiating region 131 and the second radiating region 132 along the second direction y are different to distinguish the first radiating region 131 and the second radiating region 132. The length M1 of the first radiating region 131 along the first direction x is greater than the length M2 of the second radiating region 132 along the first direction x, and the second radiating region 132 is coupled to the cooperating section 160. In this way, by utilizing the coupling between multiple metal radiators, the energy of each frequency band can be excited to achieve an ultra-wideband and multi-functional frequency band antenna structure 100. Furthermore, both the first radiation region 131 and the second radiation region 132 are rectangular. The length M1 of the first radiation region 131 along the first direction x is greater than its length along the second direction y, and the length M2 of the second radiation region 132 along the first direction x is greater than its length along the second direction y. Therefore, the operating frequency bands of the first radiation region 131 and the second radiation region 132 are related to their lengths M1 and M2 along the first direction x, respectively. The operating frequency band of the first radiation region 131 is lower than that of the second radiation region 132, and the second radiation region 132 is closer to and coupled to the cooperating unit 160 than the first radiation region 131, thereby extending and widening the operating frequency band of the second radiation region 132 to a higher frequency.

[0046] The second radiation region 132 may include an open segment 136, which extends from the connection point 135 between the second radiation region 132 and the second connection region 152 of the connection portion 150 to an open end 137. The length M3 of the open segment 136 along the first direction x is less than the length L of the first cooperative region 161 of the cooperative portion 160 along the first direction x. This facilitates frequency offset adjustment, ensuring that the operating frequency band falls within the desired frequency band. In this embodiment, the length M3 is 2.75 mm and the length L is 4.5 mm.

[0047] The grounding portion 140 may include one or more grounding areas. In this embodiment, the grounding portion 140 includes two grounding areas, namely a first grounding area 141 and a second grounding area 142, which are directly electrically connected and perpendicular to each other. This helps to adjust the radiation characteristics of the antenna structure 100, such as the operating frequency band and radiation pattern, to meet application requirements. Furthermore, it should be understood that the area of ​​the first grounding area 141 and the second grounding area 142, or their proportion to the dimensions of other elements in the antenna structure 100, is not proportional to the size of the other elements. Figures 1 to 5 The disclosure is limited.

[0048] Each of the radiating part 130, the grounding part 140, the connecting part 150, and the cooperating part 160 may be made of metal. Each of the radiating part 130, the first grounding area 141, the second grounding area 142, the connecting part 150, and the cooperating part 160 may be flat and thus a metal sheet, wherein the thickness of the metal sheet is not limited to... Figures 1 to 5 The disclosure is limited to [specific details]. This helps to reduce the manufacturing complexity of the antenna structure 100 and save manufacturing costs.

[0049] The normal directions of each of the connecting part 150, the cooperating part 160, and the second grounding area 142 can be parallel to the second direction y, and the connecting part 150, the cooperating part 160, and the second grounding area 142 are all disposed on the same plane. Specifically, the connecting part 150 and the cooperating part 160 are arranged along the first direction x and are directly electrically connected to the second grounding area 142, that is, the second grounding area 142 is electrically connected between the connecting part 150 and the cooperating part 160. The normal directions of each of the radiating part 130 and the first grounding area 141 can be parallel to the third direction z, and the first direction x, the second direction y, and the third direction z are perpendicular to each other. In this way, the three-dimensional antenna structure 100 helps to meet the application requirements of wider bandwidth or new bandwidth without increasing the number of antennas or the layout volume. Specifically, the antenna structure 100 is an integrally formed three-dimensional bent metal sheet antenna including a radiating part 130, a grounding part 140, a connecting part 150 and a cooperating part 160, and the dielectric material of the antenna structure 100 is air, but the dielectric material is not limited to this.

[0050] The cooperating section 160 and the second radiation region 132 can correspond along the first direction x, that is, the projections of the cooperating section 160 (especially the first cooperating region 161) and the second radiation region 132 in the first direction x at least partially overlap or at least partially share the same coordinates. This facilitates the extension and widening of the operating frequency band of the second radiation region 132 to higher frequencies.

[0051] The connection portion 150 may include one or more connection areas. In this embodiment, the connection portion 150 includes at least two connection areas, namely at least a first connection area 151 and a second connection area 152. The first connection area 151 and the second connection area 152 are arranged along a first direction x and electrically connected. The ground portion 140, the first connection area 151, and the second connection area 152 are electrically connected sequentially. A portion of the second connection area 152 (e.g., the portion of the second connection area 152 for providing the feed port 170) is closer to the ground portion 140 than a portion of the first connection area 151, and the second connection area 152 is provided for providing the feed port (i.e., the signal feed position) 170. Thereby, the metal radiator of the first radiation area 131 is electrically connected after the path of the feed port 170 extends, and current or energy flows from the feed port 170 to the first radiation area 131, resonating radiated energy in the 2.4GHz to 2.5GHz frequency band. The metal radiator of the second radiation region 132 is electrically connected after the path extension of the feed port 170. Current or energy flows from the feed port 170 to the second radiation region 132, resonating to generate radiated energy in the 5.15 GHz to 5.85 GHz frequency band. Furthermore, the metal radiator of the cooperating part 160 extends from the second junction area 142 and couples with the second connection area 152 extending from the feed port 170 and the second radiation region 132 respectively, resonating to generate radiated energy in the 5.85 GHz to 7.125 GHz frequency band through coupling.

[0052] The second connection region 152 provided at the feed port 170 can be closer to the cooperating unit 160 than the first connection region 151. In this way, the energy coupling between the feed signal of the second connection region 152 and the cooperating unit 160 helps the antenna structure 100 to have a wider bandwidth or an additional bandwidth.

[0053] Please refer to Figure 1 , Figure 4 and Figure 5The cooperating section 160 may include one or more cooperating areas. In this embodiment, the cooperating section 160 includes two cooperating areas, namely a first cooperating area 161 and a second cooperating area 162. The radiation area closest to the cooperating section 160 in the radiation section 130 is the second radiation area 132, and the length M2 of the second radiation area 132 along the first direction x may be greater than the length L of the first cooperating area 161 of the cooperating section 160 along the first direction x. The length L of the first cooperating area 161 of the cooperating section 160 along the first direction x may satisfy the following condition: 4mm ≤ L ≤ 10mm. This facilitates the application of antenna structure 100 in the radio frequency front-end unit of a WIFI 6E system. For example, when the dielectric material of antenna structure 100 is air, the length M1 of the first radiating region 131 along the first direction x is approximately 26.05 mm, and its operating frequency band is approximately 2.4 GHz. The length M2 of the second radiating region 132 along the first direction x is approximately 6.05 mm, and its operating frequency band is approximately 5 GHz. Furthermore, by coupling the second radiating region 132 of the radiating region 130 and the second connecting region 152 of the connecting region 150 through the first cooperating region 161 of the cooperating part 160, the operating frequency band of antenna structure 100 can be extended from approximately 5 GHz to approximately 6 GHz. Thus, based on the planar inverted-F antenna (PIFA) architecture formed by the radiating part 130, the grounding part 140, and the connecting part 150, in addition to supporting the original approximately 2.4 GHz and approximately 5 GHz, the operating frequency band can be extended from approximately 5 GHz to approximately 6 GHz, thereby contributing to WIFI... The RF front-end unit of the 6E system is easy to engineer and saves on component costs, enabling the WIFI 6E system to solve the channel congestion problem by directly adding channels.

[0054] Figure 6 Draw Figure 1 The frequency response diagram of the antenna structure 100 in this embodiment is specifically a diagram showing the relationship between the frequency and voltage standing wave ratio (VSWR) of the antenna structure 100 at different lengths L. Please refer to... Figure 1 and Figure 6The antenna structure 100 can provide operating frequency bands of 2.4 GHz to 2.5 GHz and 5.15 GHz to 7.125 GHz that comply with the WIFI 6E standard, wherein the voltage standing wave ratio (VSWR) of the operating frequency band is less than or equal to 2. According to a specific configuration of this embodiment, when the dielectric material of the antenna structure 100 is air, the length M1 is 26.05 mm, the length M2 is 6.05 mm, the gap G1 is 0.5 mm, and the gap G2 is 0.5 mm, adjusting the length L of the first cooperating region 161 along the first direction x, the approximately 2.4 GHz operating frequency band contributed by the first radiating region 131 is less affected, while the approximately 5 GHz operating frequency band contributed by the second radiating region 132 coupled to the first cooperating region 161 and its widened operating frequency band extending to higher frequencies (i.e., approximately 6 GHz) shows more significant changes in VSWR and impedance matching with the length L. The electrical length of the cooperating portion 160 can be related to 1 / 4 wavelength of the operating frequency.

[0055] Please refer to Figure 1 and Figure 4 The radiating region closest to the cooperating region 160 in the radiating section 130 is the second radiating region 132, and the cooperating region closest to the second radiating region 132 in the cooperating region 160 is the first cooperating region 161. The first cooperating region 161 is specifically rectangular, and its length L along the first direction x is greater than its length along the third direction z. The gap (i.e., gap length) along the third direction z between the first cooperating region 161 and the second radiating region 132 of the cooperating region 160 is G1, which satisfies the following condition: 0.1mm ≤ G1 ≤ 0.9mm. Therefore, an antenna structure 100 meeting the required characteristics can be effectively designed by adjusting the gap G1. Furthermore, the gap G1 and the length L satisfy the following condition: 0.02 ≤ G1 / L ≤ 0.095, thereby allowing the antenna structure according to the present invention to be applied to any desired frequency and dielectric material.

Please refer to... Figure 1 and Figure 7 The coupling amount, coupling characteristics, and gap G1 between the first cooperative region 161 and the second radiating region 132 along the third direction z are related. According to a specific configuration of this embodiment, when the dielectric material of the antenna structure 100 is air, the length M1 is 26.05 mm, the length M2 is 6.05 mm, the length L is 4.5 mm, the gap G2 is 0.5 mm, and the adjusted gap G1 is 0.5 mm, the antenna structure 100 has better impedance matching and lower voltage standing wave ratio in the range of 5.85 GHz to 7.125 GHz.

[0057] Please refer to Figure 1 and Figure 4 The gap G2 between the cooperating part 160 and the second connection area 152 provided at the feed port 170 along the first direction x satisfies the following condition: 0.3mm ≤ G2 ≤ ​​0.7mm. Therefore, an antenna structure 100 meeting the required characteristics can be effectively designed by adjusting the gap G2. Furthermore, the gap G2 and the length L satisfy the following condition: 0.06 ≤ G2 / L ≤ 0.08, thereby allowing the antenna structure according to the present invention to be applied to any desired frequency and dielectric material.

[0058] Figure 8 Draw Figure 1 Another frequency response diagram of the antenna structure 100 in the embodiment is specifically a diagram showing the relationship between the frequency and voltage standing wave ratio of the antenna structure 100 under different gaps G2. Please refer to... Figure 1 and Figure 8 The coupling amount, coupling characteristics, and gap G2 between the first cooperative region 161 and the second connection region 152 provided at the feed port 170 are related. According to a specific configuration of this embodiment, when the dielectric material of the antenna structure 100 is air, the length M1 is 26.05 mm, the length M2 is 6.05 mm, the length L is 4.5 mm, the gap G1 is 0.5 mm, and the adjustment gap G2 is 0.5 mm, the antenna structure 100 has better impedance matching and lower voltage standing wave ratio in the range of 5.85 GHz to 7.125 GHz.

[0059] According to embodiments of the present invention, when any one of the radiating part, grounding part, connecting part, and cooperating part includes at least two regions (i.e., more than one region) and is plate-shaped, the two regions can be respectively disposed on different planes that are physically connected to each other. For example, the first grounding region 141 and the second grounding region 142 are disposed perpendicularly to each other. The two regions can also be disposed on the same plane, but the electromagnetic radiation modes and characteristics of the two regions are different. For example, the first radiation region 131 and the second radiation region 132 have discontinuous changes in length along the second direction y at their structural boundary. The length of the first radiation region 131 along the second direction y is greater than the length of the second radiation region 132 along the second direction y. Therefore, the first radiation region 131 and the second radiation region 132 generate different frequency modes related to the lengths M1 and M2 of the first direction x, respectively.

[0060] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art should be able to make various modifications and refinements without departing from the spirit and scope of the present invention.
