Detailed Description
The invention has the core of providing an antenna and electronic equipment, wherein the equipment can effectively complete man-machine interaction with high difficulty and multiple changes by using less energy, reduces the influence of electromagnetic radiation environment on a user, and improves the use experience of the user.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an antenna according to an embodiment of the invention.
The antenna is applied to electronic equipment comprising a functional circuit board 203, and comprises a dielectric substrate, a feed patch 100, a grounding patch 101 and an extension patch 102 which are arranged on the dielectric substrate; the extension patch 102 is connected with the ground patch 101; the antenna further comprises:
a coaxial feeder 103 having a core connected to the feeding patch 100 and a casing connected to the ground patch 101;
a coupling part a connected to the extension patch 102 and the functional circuit board 203, respectively, for electrically coupling the extension patch 102 and the functional circuit board 203;
the feeding patch 100 is used for generating an operating frequency band covering a preset target bandwidth under the combined action of the feeding excitation of the coaxial feeder 103, the grounding patch 101, the extension patch 102 and the functional circuit board 203.
Specifically, the antenna of the present application includes a dielectric substrate (not shown in fig. 1), a feeding patch 100, a grounding patch 101, an extension patch 102, a coaxial feeder 103, and a coupling portion a, and the working principle thereof is as follows:
the feeding patch 100, the grounding patch 101 and the extension patch 102 are all arranged on a dielectric substrate, and the feeding patch 100, the grounding patch 101 and the extension patch 102 are all metal patches, and are made of metal materials with better conductivity and lower cost, such as copper. The extension patch 102 is connected to the ground patch 101, and the ground patch 101 is connected to the device Ground (GND) of the electronic device in which it is located.
The antenna is fed by a coaxial feed, i.e. radio frequency energy is transmitted via a coaxial feed line 103. The coaxial feeder 103 is formed by an inner layer, a middle layer and an outer layer, wherein the innermost layer is a wire core, and copper metal is generally selected; the middle layer structure is an insulating medium layer; the outermost layer structure is a shell, and copper metal is generally selected as a metal shielding layer, so that the anti-interference capability of the coaxial feeder 103 is enhanced, and the transmission loss of the coaxial feeder 103 is reduced.
The specific connection structure of the coaxial feeder 103 is: the core of the coaxial feed 103 is connected to the feed patch 100 and the outer shell of the coaxial feed 103 is connected to the ground patch 101. If the electronic device is a transmitting device, the electronic device may transmit radio frequency energy to the feeding patch 100 through the coaxial feeder 103, and be transmitted by the feeding patch 100 as an antenna; if the electronic device is a receiving device, the electronic device may receive the rf energy transmitted from the outside through the feeding patch 100, and transmit the rf energy to the electronic device through the coaxial feeder 103 for internal processing.
The electronic device includes a main circuit board 200 and a plurality of functional circuit boards (not limited to the four functional circuit boards 201, 202, 203, 204 shown in fig. 1) distributed on two sides of the main circuit board 200, where the extension patch 102 is connected to a functional circuit board 203 of the electronic device through a coupling portion a, and the coupling portion a electrically couples the extension patch 102 and the functional circuit board 203 (the electric coupling is substantially that there is a charge movement between the extension patch 102 and the functional circuit board 203). The feeding patch 100 cooperates with the grounding patch 101, the extension patch 102 and the functional circuit board 203 under the excitation of the coaxial feeder 103 to generate an operating frequency band covering a preset target bandwidth, for example, a 5G millimeter wave broadband antenna and a bluetooth frequency band antenna are designed.
It should be noted that the radiation of the antenna in the operating frequency band includes main lobe radiation and side lobe radiation, and the larger the main lobe radiation is, the better the larger the side lobe radiation is, and the smaller the side lobe radiation is. As shown in fig. 2, when the antenna is in operation, the feeding patch 100 generates a current path distribution 11, and at this time, the grounding patch 101 excites a new current path 12 through the extension patch 102, and due to the presence of the coupling portion a, the new current path 12 can radiate through the functional circuit board 203, so that the current path and the feeding patch 100 radiate together in a designed operating frequency band, and the main lobe radiation of the antenna can be enhanced. In addition, on the original structure of the antenna (dielectric substrate+feeding patch+grounding patch+coaxial feeder), because there is electrical coupling between the feeding patch 100 and the functional circuit board 203, the functional circuit board 203 consumes part of the current radiation energy on the feeding patch 100, so as to reduce the radiation of the main lobe of the antenna and enhance the radiation of the side lobe of the antenna, but after the extension patch 102 and the coupling part A are added, the current path generated by the grounding patch 101 is reversely coupled to the feeding patch 100 through the functional circuit board 203, so as to generate reverse current paths 13 and 14 as shown in fig. 3, thereby increasing the current radiation energy on the feeding patch 100, which is equivalent to reducing the current radiation energy on the feeding patch 100 consumed by the functional circuit board 203, and enhancing the radiation of the main lobe of the antenna and reducing the radiation of the side lobe of the antenna.
Based on this, compare in the original structure of antenna, the main lobe radiation of the antenna structure of this application is great, the sidelobe radiation is less, has following beneficial effect:
1) The electronic equipment (the handheld controller) can effectively complete man-machine interaction with high difficulty and multiple changes by using less energy; 2) The influence of electromagnetic radiation environment on the user is reduced; 3) The interaction rate of the head-mounted display device and the handheld controller is improved, and interaction time delay of the head-mounted display device and the handheld controller is reduced, so that the use experience of a user is improved.
Based on the above embodiments:
as an alternative embodiment, the extended patch 102 includes:
a first rectangular patch connected to the ground patch 101;
and the second rectangular patch is respectively connected with the first rectangular patch and the coupling part A and is perpendicular to the first rectangular patch.
Specifically, the extension patch 102 of the present application includes a first rectangular patch and a second rectangular patch, and the working principle thereof is:
the first rectangular patch is connected with the grounding patch 101, the second rectangular patch is connected with the first rectangular patch and the coupling portion a respectively, and the second rectangular patch is perpendicular to the first rectangular patch, that is, the first rectangular patch and the second rectangular patch form an L-shaped structure, so that the extension patch 102 and the functional circuit board 203 form an electric coupling structure.
By adjusting the width of the extension patch 102, the antenna may achieve a suitable current path length for enhancing the antenna main lobe radiation.
As an alternative embodiment, the feeding patch 100 includes:
a third rectangular patch;
a fourth rectangular patch shorter than the third rectangular patch and disposed parallel to the third rectangular patch;
and a fifth rectangular patch connected to the third rectangular patch and the fourth rectangular patch, respectively, and perpendicular to the third rectangular patch and the fourth rectangular patch.
Specifically, the feeding patch 100 of the present application includes a third rectangular patch, a fourth rectangular patch, and a fifth rectangular patch, and the working principle thereof is:
the third rectangular patch and the fourth rectangular patch are arranged on the medium substrate in parallel, the length of the third rectangular patch is larger than that of the fourth rectangular patch, the fifth rectangular patch is connected with the third rectangular patch and the fourth rectangular patch respectively, and the fifth rectangular patch is perpendicular to the third rectangular patch and the fourth rectangular patch. The feeding patch 100 has better radiation performance under the structural design.
As an alternative embodiment, the third rectangular patch, the fourth rectangular patch and the fifth rectangular patch form a C-shaped structure, and the opening of the C-shaped structure faces the functional circuit board 203.
Specifically, the third rectangular patch, the fourth rectangular patch and the fifth rectangular patch on the feeding patch 100 of the present application form a C-shaped structure, as shown in fig. 1, the feeding patch 100 is located between the functional circuit board 202 and the functional circuit board 203, an opening portion of the C-shaped structure faces the functional circuit board 203 (the functional circuit board electrically coupled with the extension patch 102), and a bending portion of the C-shaped structure is close to the functional circuit board 202, that is, the fifth rectangular patch is close to the functional circuit board 202.
Compared with other design positions of the feeding patch 100 between the functional circuit board 202 and the functional circuit board 203, the feeding patch 100 can reduce the current radiation energy consumed by the functional circuit board 203 on the feeding patch 100 under the design of the positions, thereby being beneficial to enhancing the main lobe radiation of the antenna and reducing the side lobe radiation of the antenna.
It should be noted that, by adjusting the distances between the functional circuit board 202, the functional circuit board 203 and the feeding patch 100 and the width of the feeding patch 100, the reverse current path length shown in fig. 3 can be adjusted, so as to reduce the antenna side lobe radiation.
As an alternative embodiment, the dielectric substrate is a flexible dielectric substrate.
Specifically, the dielectric substrate of the application is a flexible dielectric substrate, and medium such as FR4 (code of flame-retardant material grade), PI (Polyimide) and the like with lower cost can be selected to form the dielectric substrate, namely, the antenna of the application is an FPC (Flexible Printed Circuit, flexible circuit board) antenna, and the antenna has the characteristics of light weight, thin thickness and good flexibility.
In addition, the main circuit board 200 and the plurality of functional circuit boards distributed on both sides of the main circuit board 200 may be FPC circuit boards.
As an alternative embodiment, the coupling part a includes:
the upper surface is connected with the lower surface of the functional circuit board 203 through conductive adhesive, and the lower surface is connected with the reinforcing plate of the upper surface of the extension patch 102 through non-conductive adhesive.
Specifically, the coupling portion a of the present application is divided into three layers: the first layer is conductive adhesive; the second layer is a reinforcing plate; the third layer is a non-conductive adhesive. One of the conductive adhesive is used for adhering the reinforcing plate to the lower surface of the functional circuit board 203, and the other conductive adhesive is used for having conductive property and participating in the electric coupling between the extension patch 102 and the functional circuit board 203 so as to shorten the electric coupling distance between the extension patch 102 and the functional circuit board 203, so that the electric coupling effect is better; the function of the reinforcing plate is to protect the devices on the functional circuit board 203 from being broken; the non-conductive adhesive is used to adhere the extension patch 102 to the lower surface of the stiffening plate, so as to realize strong coupling between the extension patch 102 and the functional circuit board 203, and the non-conductive adhesive is selected because the extension patch 102 is a conductive patch, and the non-conductive adhesive does not affect the original conductivity of the extension patch 102.
For example, the functional circuit board 203 may be a light-emitting circuit board (not limited to the LED lamp function, but may be a detection circuit board provided with a sensor) provided with an LED (light-emitting diode), as shown in fig. 4, 301 is an LED lamp; 302 is a lamp FPC;303 is conductive adhesive with thickness of 0.1mm;304 is a stiffening plate; 104 is non-conductive adhesive with thickness of 0.1mm;102 is an extension patch.
It should be noted that, the degree of electrical coupling between the extension patch 102 and the functional circuit board 203 may be adjusted by adjusting the thickness of the non-conductive adhesive layer and the overlapping area of the extension patch 102 and the functional circuit board 203, specifically, the thicker the thickness of the non-conductive adhesive layer, the lower the degree of electrical coupling between the extension patch 102 and the functional circuit board 203; the greater the overlapping area of the extended patch 102 and the functional circuit board 203, the higher the degree of electrical coupling of the extended patch 102 and the functional circuit board 203.
As an alternative embodiment, the functional circuit board 203 is a circuit board having a width ranging from 7.9mm to 8.1mm, a length ranging from 9.9mm to 10.1mm, and a thickness ranging from 0.2mm to 0.4 mm; the reinforcing plate is 7.9-8.1 mm wide, 9.9-10.1 mm long and 0.4-0.6 mm thick.
Specifically, the functional circuit board 203 of the present application has a width ranging from 7.9mm to 8.1mm, a length ranging from 9.9mm to 10.1mm, and a thickness ranging from 0.2mm to 0.4mm, and for example, a functional circuit board having a width ranging from 8mm, a length ranging from 10mm, and a thickness ranging from 0.3mm may be selected. In this case, the reinforcing plate has a width in the range of 7.9mm to 8.1mm, a length in the range of 9.9mm to 10.1mm, and a thickness in the range of 0.4mm to 0.6mm, and for example, a reinforcing plate having a width in the range of 8mm, a length in the range of 10mm, and a thickness in the range of 0.5mm may be selected. While the length of the extended patch 102 may be equal to the length of the functional circuit board 203, the width of the extended patch 203 may be equal to the width of the functional circuit board 203, so that the extended patch 102 and the functional circuit board 203 are substantially completely overlapped, and the electric coupling degree between the extended patch 102 and the functional circuit board 203 is high.
In addition, the antenna radiation pattern simulation can be carried out on the original structure of the antenna and the improved structure of the antenna after the extension patch and the coupling part are additionally arranged, so that a simulation comparison result is obtained: the directivity coefficient of the original structure of the antenna is 2.88, and the side lobe radiation is obvious; the directivity coefficient of the improved structure of the antenna is improved to 3.4, the side lobe radiation is obviously weakened, and the performance of the antenna is excellent.
The application also provides electronic equipment, which comprises the functional circuit board and any antenna.

As an alternative embodiment, the electronic device is a handheld controller.
Specifically, the electronic equipment is a handheld controller, and is matched with a head-mounted display device to form wearing type man-machine interaction equipment such as VR and AR.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a handheld controller according to an embodiment of the invention.
As an alternative embodiment, the hand-held controller comprises:
a handle 400;
a support portion 401 connected to the handle 400; the functional circuit board and the antenna are provided on the supporting portion 401;
