Description

Technical Field

[0001] The present application relates to the field of remote control technology, and in particular to an antenna for an air mouse remote control. Background Art

[0002] With the rapid development of modern communication technology, wireless communication devices have become an indispensable part of daily life. Especially in the field of smart devices, antennas are key components for converting electromagnetic waves into electrical signals, and their performance directly affects the communication efficiency and user experience of the device. For example, devices such as mobile phones and computers rely on efficient antennas to maintain stable wireless connections.

[0003] The popularity of smart TVs and the rich and diverse content they provide require users to be able to interact with the TV quickly and naturally. Traditional button remote controls can no longer fully meet the interactivity needs of modern users due to their operational limitations. Users need to be able to quickly move the focus, browse web pages, select products, and input information. The implementation of these operations on smart TVs is fundamentally different from that on mobile devices. Due to the limitation of operating distance, smart TVs cannot be controlled by touch screens, but must rely on remote controls to achieve long-distance interactive control.

[0004] This change in interaction mode has put forward higher requirements for antenna design. The antenna not only needs to maintain a simple structure and small size to adapt to the trend of thinness and lightness of modern electronic devices, but also must have excellent electrical and radiation performance to ensure effective transmission and reception of signals, thereby achieving an efficient and smooth user interaction experience. Summary of the invention

[0005] The purpose of the present application is to provide an antenna for an air mouse remote control, which can integrate multiple antennas into a smaller dielectric substrate while taking into account effective signal transmission and reception, thereby achieving an efficient and smooth user interaction experience.

[0006] The present application discloses an antenna for an air mouse remote control, comprising: a dielectric substrate 1, a plurality of bottom radiation units 2, a plurality of side radiation units 3, a first metal layer 4 and a plurality of dielectric ridges 5;

[0007] The dielectric ridge 5 vertically protrudes upward from the top surface of the dielectric substrate 1, and the first metal layer 4 is provided on the top surface of the dielectric substrate 1;

[0008] The plurality of bottom radiation units 2 are all arranged on the bottom surface of the dielectric substrate 1, and the bottom radiation units 2 are all provided with slots 6 and feeding structure holes 7, and the bottom radiation units 2 are connected to the first metal layer 4 through the second metal layer 8 on the inner wall of the slots 6;

[0010] The number of the bottom radiation units 2 and the number of the side radiation units 3 are equal, and the positions of each bottom radiation unit 2 and each side radiation unit 3 correspond to each other.

[0011] In a preferred example, a radiation gap 10 is formed between the bottom radiation unit 2 and the side radiation unit 3 at corresponding positions, and the radiation gap 10 is arranged along the top side edge of the dielectric substrate 1 in the length direction.

[0012] In a preferred example, a printed circuit board is further included, the dielectric substrate 1 is connected to the printed circuit board, and the printed circuit board is configured to send a radio frequency signal to the dielectric substrate 1 .

[0013] In a preferred example, the printed circuit board is connected to the bottom surface of the dielectric substrate 1 through a feeding unit, and the feeding unit includes a plurality of feeding probes and a plurality of coplanar waveguide feeding lines;

[0014] The first ends of the plurality of feeding probes are respectively connected to the feeding structure holes 7 , and the second ends of the feeding probes are respectively connected to the coplanar waveguide feed lines, which are integrated on the printed circuit board.

[0015] In a preferred example, the slot 6 is a rectangular slot 6 .

[0016] In a preferred example, the feeding structure hole 7 is a countersunk hole.

[0017] In a preferred example, the geometric center of the bottom radiation unit 2 is an isosceles triangle on the bottom surface of the dielectric substrate 1 .

[0018] In a preferred example, the dielectric ridges 5 are arranged along both sides of the dielectric substrate 1 in the length direction.

[0019] In a preferred example, the feeding probe is located between the slot 6 and the radiation slot 10 , and the feeding probe is close to the slot 6 .

[0020] In a preferred example, the depth of the groove 6 is equal to the thickness of the dielectric substrate 1 .

[0021] In the implementation manner of the present application, by providing a dielectric ridge protruding from the top surface of the dielectric substrate, the stability of the structure can be further enhanced, and the centralized transmission of the signal can be facilitated. In addition, by combining the bottom radiation unit and the side radiation unit, the antenna can achieve a wider radiation coverage range, and can effectively send and receive signals in different directions, thereby enhancing the reliability of the air mouse remote control in space operation. The third metal layer and the second metal layer are respectively connected to the first metal layer, which can ensure the consistency of the electrical performance of the entire antenna system. The interconnection of the metal layers ensures the efficiency and uniformity of signal transmission, thereby improving the overall performance of the antenna;

[0022] Furthermore, the radiation gap can enhance the radiation directivity and overall radiation efficiency of the antenna, thereby improving the responsiveness and accuracy of the air mouse remote control;

[0023] Furthermore, the feeding probe and the coplanar waveguide feed line can not only ensure the efficient transmission of the RF signal, but also reduce the signal loss during the transmission process, thereby improving the performance of the entire antenna.
