Description

Technical Field

[0001] This application relates to the field of antenna technology, and more specifically, to a high-gain planar antenna and electronic device. Background Technology

[0002] Electronic devices (such as recording and broadcasting equipment) are usually equipped with antennas to transmit and receive wireless signals. To enhance the communication capabilities of the antennas, high-gain antennas are usually used in electronic devices.

[0003] In related technologies, it is usually necessary to increase the size of the antenna to achieve high gain. This results in a large overall size of the antenna, which is difficult to integrate and occupies a lot of space in electronic devices, which is not conducive to the miniaturization of electronic devices. Utility Model Content

[0004] To address the aforementioned issues, this application provides a high-gain planar antenna and electronic device, aiming to solve the problems that high-gain antennas have a large overall size, are difficult to integrate, and occupy a large space within electronic devices, which is detrimental to the miniaturization of electronic devices.

[0005] In a first aspect, this application provides a high-gain planar antenna, which includes a carrier, a first grounding element, a radiating element, and a second grounding element; a grounding region is formed on the carrier; the first grounding element is electrically connected to the grounding region; the radiating element is electrically connected to the grounding region, and the electromagnetic field direction of the first grounding element is opposite to that of the radiating element; the second grounding element is connected to the grounding region, and the electromagnetic field direction of the second grounding element is the same as that of the radiating element; wherein the first grounding element, the radiating element, and the second grounding element are located on the same side of the carrier, and the radiating element is located between the first grounding element and the second grounding element.

[0006] In this implementation, initially, the radiating dipole provides initial radiation to both sides away from it. At this time, the radiating dipole is located between the first and second grounding dipoles. The radiating dipole then provides electromagnetic waves in the direction of the first and second grounding dipoles. The first grounding dipole is located on one side of the radiating dipole, and its electromagnetic field direction is opposite to that of the radiating dipole. The first grounding dipole acts as a "reflector," reflecting the electromagnetic waves from the side away from the radiating dipole, allowing them to propagate towards the radiating dipole and ultimately radiate towards the other side away from it. The second grounding dipole is located on the other side of the radiating dipole, and its electromagnetic field direction is the same as that of the radiating dipole. The second grounding dipole guides the electromagnetic waves from the other side away from the radiating dipole, ensuring they continue to radiate towards that direction. Thus, the electromagnetic waves provided by the radiating element are all radiated in a direction away from the radiating element, and the electromagnetic waves reflected by the first grounding element coincide with the electromagnetic waves guided by the second grounding element, thereby strengthening the electromagnetic waves radiated in a direction away from the radiating element. This means the high-gain planar antenna provided in this application has strong directivity, enabling it to achieve high gain. Secondly, the first grounding element, the radiating element, and the second grounding element are all planar structures, meaning the overall volume of the high-gain planar antenna is small and easy to integrate. Compared to related technologies where achieving high gain requires increasing the volume of the antenna cavity, the antenna in this application is a high-gain planar antenna, achieving high gain without increasing the antenna cavity, resulting in a smaller footprint within the device body and facilitating the miniaturization of electronic devices.

[0007] In one possible implementation, the length of the first grounding element is greater than the length of the radiating element.

[0008] In this implementation, the length of the first grounding element is greater than the length of the radiating element, so that the electromagnetic waves radiated by the radiating element toward the side away from the radiating element can be completely reflected by the first grounding element and transmitted toward the direction closer to the radiating element, and finally radiated toward the other side away from the radiating element, thereby improving the reflection reliability of the first grounding element, and thus improving the reliability of the high-gain planar antenna to achieve high gain.

[0009] In one possible implementation, the distance between the first grounding element and the radiating element is one-quarter wavelength.

[0010] In this implementation, while achieving high gain for the high-gain planar antenna, the spacing between the first grounding element and the radiating element is small, thereby reducing the volume of the high-gain planar antenna, making it easy to integrate, and further reducing the space it occupies in the main body of the device, which is conducive to the miniaturization of electronic devices.

[0011] In one possible implementation, the length of the second grounding element is less than or equal to the length of the radiating element.

[0012] In this implementation, the electromagnetic waves radiated by the radiating oscillator in a direction away from the radiating oscillator can be completely guided by the second grounding oscillator to be transmitted in a direction away from the radiating oscillator, thereby improving the transmission reliability of the electromagnetic waves in the direction away from the radiating oscillator.

[0013] In one possible implementation, the length of the radiating oscillator is 10–14 mm.

[0014] In one possible implementation, the radiating oscillator includes a linear oscillator arm and a bent arm; one end of the linear oscillator arm is electrically connected to a grounded area; the bent arm is connected to the other end of the linear oscillator arm and is set at an angle to the linear oscillator arm.

[0015] In this implementation, by adjusting the angle and position between the bent arm and the straight arm, the radiation of the radiating element in a specific direction can be enhanced, that is, the directional gain of the radiating element can be increased, and the additional sidelobe radiation can be reduced, thereby improving the communication quality of the high-gain planar antenna.

[0016] In one possible implementation, the radiating oscillator can be any of the following types: upright, bent, or rectangular.

[0017] In this implementation, when the radiating oscillator is upright, the manufacturing cost is low and it is easy to manufacture and install; when the radiating oscillator is bent, it can enhance the radiation of the radiating oscillator in a specific direction to improve the directional gain of the radiating oscillator; when the radiating oscillator is rectangular, it is small in size and light in weight, easy to integrate with the carrier, and suitable for high-frequency applications.

[0018] In one possible implementation, the high-gain planar antenna includes a plurality of second grounded elements, which are spaced apart on the same side of the carrier.

[0019] In this implementation, multiple second grounding elements can guide electromagnetic waves radiated in a direction away from the radiating element to be transmitted in the same direction away from the radiating element, thereby further improving the directionality of electromagnetic wave transmission and thus further improving the transmission reliability of electromagnetic waves in the direction away from the radiating element, so as to ensure the high gain effect of the high-gain planar antenna.

[0020] In one possible implementation, the second grounding element can be any one of the following: upright, T-shaped, or inverted L-shaped.

[0021] Secondly, embodiments of this application provide an electronic device, including a device body and a high-gain planar antenna as described in any optional manner of the first aspect, wherein the high-gain planar antenna is mounted on the device body. Attached Figure Description

[0033] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, and circuits have been omitted so as not to obscure the description of this application with unnecessary detail.

[0034] Electronic devices (such as recording and broadcasting systems) typically incorporate antennas to transmit and receive wireless signals, ensuring normal operation. To enhance the communication capabilities of these devices, the antenna's communication capacity must be correspondingly improved, often requiring high-gain antennas. Currently, some antennas employ rod-shaped structures with a maximum gain of only 6dBi; others use high-frequency array antennas to achieve high gain. However, array antennas occupy relatively large spaces in the 5GHz band, hindering miniaturization. Furthermore, some antennas utilize reflector structures to increase gain, aiming to achieve a preset high gain through reflection. For example, to achieve a gain of 9-10dBi, the reflector height must be 40-50mm, requiring a 50mm radius and height antenna cavity. This results in a large overall antenna size, making integration difficult and occupying significant space within the device, further hindering miniaturization.

[0035] Therefore, this application provides a high-gain planar antenna and an electronic device. The high-gain planar antenna has strong directivity to achieve high gain, and its overall size is small, easy to integrate, and occupies little space in the main body of the device.

[0036] The high-gain planar antenna and electronic device provided in this application are described below with reference to the accompanying drawings.

[0037] like Figure 1 As shown, the electronic device provided in this application includes a high-gain planar antenna 1 and a device body 2. The high-gain planar antenna 1 is mounted on the device body 2 to realize the transmission and reception of wireless signals, thereby ensuring the normal use of the device body 2.

[0038] For example, such as Figure 2 As shown, the main body 2 of the device provided in this application can be a recording and broadcasting unit. The recording and broadcasting unit is provided with a receiving cavity 2A. The high-gain planar antenna 1 can be set on the cavity sidewall of the receiving cavity 2A to realize the transmission and reception of wireless signals. The main body 2 of the device provided in this application can also be a router or other devices that need to be configured with a high-gain planar antenna 1. This application does not impose specific restrictions on this.

[0039] In order to enable the high-gain planar antenna 1 provided in this application to achieve high gain, in one example, such as Figure 2As shown, the high-gain planar antenna 1 may include a carrier 11, a first grounding element 12, a radiating element 13, and a second grounding element 14. A grounding region 11A is formed on the carrier 11. The first grounding element 12 is electrically connected to the grounding region 11A, the radiating element 13 is electrically connected to the grounding region 11A, and the second grounding element 14 is connected to the grounding region 11A. The first grounding element 12, the radiating element 13, and the second grounding element 14 are located on the same side of the carrier 11, and the radiating element 13 is located between the first grounding element 12 and the second grounding element 14. The electromagnetic field direction of the first grounding element 12 is opposite to that of the radiating element 13, and the electromagnetic field direction of the second grounding element 14 is the same as that of the radiating element 13.

[0040] In this example, the radiating element 13 is the main radiator. The radiating element 13 can convert the alternating current conducted in the transmission line into electromagnetic waves and radiate them into space. It can also receive electromagnetic waves and convert them back into current. Initially, the radiating element 13 provides initial radiation to both sides away from it. At this time, the radiating element 13 is located between the first grounding element 12 and the second grounding element 14. The radiating element 13 provides electromagnetic waves in the direction of the first grounding element 12 and the second grounding element 14. The first grounding element 12 is located on one side of the radiating element 13, and the direction of its electromagnetic field is opposite to that of the radiating element 13. At this time, the first grounding element 12 acts as a "reflector panel," reflecting the electromagnetic waves on the side away from the radiating element 13, allowing them to propagate towards the radiating element 13, and further radiating towards the other side away from the radiating element 13. The second grounding element 14 is located on the other side of the radiating element 13, and the electromagnetic field direction of the second grounding element 14 is the same as that of the electromagnetic field direction of the radiating element 13. At this time, the second grounding element 14 can guide the electromagnetic waves away from the other side of the radiating element 13, so that the electromagnetic waves continue to radiate in the direction away from the other side of the radiating element 13.

[0041] It is worth noting that this application can use opposite-phase excitation or reverse feeding to make the electromagnetic field direction of the first grounding vibrator 12 opposite to that of the radiating vibrator 13. For example, taking the opposite-phase excitation method, by applying signals of opposite phase to the radiating vibrator 13 and the first grounding vibrator 12, the electromagnetic field directions generated by the radiating vibrator 13 and the first grounding vibrator 12 are made opposite. Similarly, this application can use the same-phase excitation or same-direction feeding method to make the electromagnetic field direction of the second grounding vibrator 14 opposite to that of the radiating vibrator 13. For example, taking the same-phase excitation method, by applying signals of the same phase to the radiating vibrator 13 and the second grounding vibrator 14, the electromagnetic field directions generated by the radiating vibrator 13 and the second grounding vibrator 14 are the same. The specific setting method can be selected according to actual needs, and this application does not impose specific limitations on it.

[0042] Thus, the electromagnetic waves provided by the radiating element 13 are all radiated in a direction away from the radiating element 13, and the electromagnetic waves reflected by the first grounding element 12 coincide with the electromagnetic waves guided by the second grounding element 14, thereby strengthening the electromagnetic waves radiated in a direction away from the radiating element 13. This means the high-gain planar antenna 1 provided in this application has strong directivity, enabling it to achieve high gain. Secondly, the first grounding element 12, the radiating element 13, and the second grounding element 14 are all planar structures, resulting in a smaller overall volume and easier integration of the high-gain planar antenna 1. Compared to related technologies where achieving high gain requires increasing the volume of the antenna cavity, the high-gain planar antenna 1 in this application achieves high gain without increasing the antenna cavity, resulting in a smaller footprint within the device body 2 and facilitating the miniaturization of electronic devices. In other words, the high-gain planar antenna 1 in this application achieves high gain while reducing size.

[0043] To ensure the radiation reliability of the radiating oscillator 13, such as Figure 3 As shown, the first grounding vibrator 12, the radiating vibrator 13, and the second grounding vibrator 14 are arranged sequentially and at intervals on the same side of the bearing member 11.

[0044] In this example, Figure 4 The radiation gain diagram of the high-gain planar antenna 1 provided in this application is as follows: Figure 4 As shown, the high-gain planar antenna 1 has high directivity, and the gain of the high-gain planar antenna 1 can reach 8.6 dBi. Thus, a high gain is achieved by using a small-sized high-gain planar antenna 1. Figure 5 The return loss diagram of the high-gain planar antenna 1 provided in this application shows that the high-gain planar antenna 1 has excellent bandwidth performance at 40% of the -10dB bandwidth. Thus, the high-gain planar antenna 1 provided in this application achieves both high bandwidth and high gain.

[0045] It is worth noting that the high-gain planar antenna 1 of this application achieves high gain through the first grounding element 12, the radiating element 13, and the second grounding element 14, which is similar to the method of using a combination of a monopole and a Yagi antenna to achieve high gain.

[0046] Optionally, the spacing between the first grounding element 12 and the radiating element 13 provided in this application can be a quarter wavelength. Compared to the half-wavelength antenna element and grounding element in the Yagi antenna of the related art, the high-gain planar antenna 1 provided in this application is smaller in size and can achieve the same high gain as the Yagi antenna. Thus, when the spacing between the first grounding element 12 and the radiating element 13 is a quarter wavelength, the high-gain planar antenna 1 can achieve high gain while keeping the spacing between the first grounding element 12 and the radiating element 13 smaller, thereby reducing the volume of the high-gain planar antenna 1, making it easier to integrate, and further reducing its footprint within the main body of the device, which is beneficial to the miniaturization of electronic devices.

[0047] In one example, such as Figure 6 As shown, the radiating oscillator 13 includes a linear oscillator arm 131 and a bent arm 132. One end of the linear oscillator arm 131 is electrically connected to the grounding region 11A, and the bent arm 132 is connected to the other end of the linear oscillator arm 131 and is angled relative to the linear oscillator arm 131, for example as shown in the figure. Figure 6 As shown, the straight dipole arm 131 and the bent arm 132 are at a 90° angle. In this example, by adjusting the angle and position between the bent arm 132 and the straight dipole arm 131, the radiation of the radiating dipole 13 in a specific direction can be enhanced, that is, the directional gain of the radiating dipole 13 can be increased, and the additional sidelobe radiation can be reduced, thereby improving the communication quality of the high-gain planar antenna 1.

[0048] Optionally, the radiating oscillator 13 can also be upright or bent (e.g., as shown in the image). Figure 6 The shape can be either an inverted L-shape or a rectangle, as shown, and can be set according to actual needs. For example, assuming that to reduce manufacturing costs, the radiating oscillator 13 can be as follows: Figure 3 The vertical structure shown is low in manufacturing cost and easy to manufacture and install; assuming that the directional gain of the radiating oscillator 13 is to be improved, the radiating oscillator 13 can be as follows: Figure 6 The bent structure shown enhances the radiation of the radiating dipole 13 in a specific direction, thereby improving the directional gain of the radiating dipole 13. When the radiating dipole 13 adopts a rectangular structure, it is smaller in size and lighter in weight, making it easier to integrate with the carrier 11 and suitable for high-frequency applications, such as microwave and millimeter-wave bands. The specific structure of the radiating dipole 13 can be set according to actual needs, and this application does not impose specific limitations on it.

[0049] Optionally, the first grounding element 12 and the second grounding element 14 can also be any one of the vertical, T-shaped, and inverted L-shaped types, which will not be elaborated further.

[0050] To improve the reflection reliability of the first grounding element 12, in one example, such as Figure 7 As shown, the length of the first grounding element 12 is greater than the length of the radiating element 13. In this example, the length of the first grounding element 12 is greater than the length of the radiating element 13, so that electromagnetic waves radiated by the radiating element 13 toward the side away from the radiating element 13 can be completely reflected by the first grounding element 12 and transmitted toward the direction closer to the radiating element 13, and ultimately radiated toward the other side away from the radiating element 13, thereby improving the reflection reliability of the first grounding element 12, and thus improving the reliability of the high-gain planar antenna 1 in achieving high gain.

[0051] In one example, the length of the second grounding element 14 is less than or equal to the length of the radiating element 13. Thus, electromagnetic waves radiated by the radiating element 13 in a direction away from its opposite side can be completely guided by the second grounding element 14 to propagate in that direction, thereby improving the transmission reliability of the electromagnetic waves in that direction. For example, such as... Figure 8 As shown, the length of the second grounding dipole 14 is equal to the length of the radiating dipole 13.

[0052] In one example, to further improve the guiding reliability of the second grounding element 14, the radiating element 13 provided in this application may include a plurality of second grounding elements 14. These multiple second grounding elements 14 are spaced apart on the same side of the carrier 11 and are electrically connected to the grounding region 11A of the carrier 11. In this example, the multiple second grounding elements 14 can guide electromagnetic waves radiated in a direction away from the other side of the radiating element 13 to propagate in that direction, thereby further improving the directionality of electromagnetic wave propagation and thus further improving the transmission reliability of electromagnetic waves propagating in a direction away from the other side of the radiating element 13, ensuring the high-gain effect of the high-gain planar antenna 1.

[0053] For example, such as Figure 9As shown, the radiating element 13 provided in this application may include three second grounding elements 14 (a, b, c). The three second grounding elements 14 (a, b, c) are spaced apart on one side of the carrier 11. In this example, electromagnetic waves radiated by the radiating element 13 in a direction away from the other side of the radiating element 13 can be guided sequentially by the three second grounding elements 14 (a, b, c) to be transmitted in a direction away from the other side of the radiating element 13. By guiding the electromagnetic waves radiated in a direction away from the other side of the radiating element 13 by the three second grounding elements 14 (a, b, c), the directionality of electromagnetic wave transmission is further improved, thereby improving the transmission reliability of electromagnetic waves in a direction away from the other side of the radiating element 13, and further ensuring the high gain effect achieved by the high gain planar antenna 1.

[0054] Optionally, the length of the radiating element 13 is 10 to 14 mm, which can be set according to actual needs. For example, when the high-gain planar antenna 1 is applied to the 5 GHz band, the length of the radiating element 13 can be set to be shorter, such as 10 mm. When the high-gain planar antenna 1 is applied to the 2.4 GHz band, the length of the radiating element 13 can be set to be longer, such as 14 mm. The length of the radiating element 13 can be set according to the actual application scenario and frequency band. This application does not impose specific restrictions on this.

[0055] Optionally, the carrier 11 can be a printed circuit board (PCB), a metal part with a grounding area 11A, a cylinder with a grounding area 11A, or other carrier structures. The specific carrier can be matched and set according to the accommodating space inside the main body 2 of the device. This application does not impose specific restrictions on this.

[0056] In summary, the electromagnetic waves provided by the radiating element 13 in the high-gain planar antenna 1 of this application radiate in a direction away from the radiating element 13. Furthermore, the electromagnetic waves reflected by the first grounding element 12 coincide with the electromagnetic waves guided by the second grounding element 14, thereby strengthening the electromagnetic waves radiated in a direction away from the radiating element 13. This means the high-gain planar antenna 1 of this application has strong directivity, enabling it to achieve high gain. Moreover, the first grounding element 12, the radiating element 13, and the second grounding element 14 are all planar structures, resulting in a smaller overall size and easier integration of the high-gain planar antenna 1. Compared to related technologies where achieving high gain requires increasing the volume of the antenna cavity, the high-gain planar antenna 1 of this application achieves high gain without increasing the antenna cavity, resulting in a smaller footprint within the device body 2 and facilitating the miniaturization of electronic devices. In short, the high-gain planar antenna 1 of this application achieves high gain while reducing size.
