Description
Technical Field
The present application relates to the field of antennas, and in particular, to an antenna structure and a wireless transmission device.
Background
An antenna (antenna) is a transducer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium, usually free space, or vice versa. A component for transmitting or receiving electromagnetic waves in a radio device. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like all use electromagnetic waves to transmit information and work by depending on antennas. In addition, in transferring energy with electromagnetic waves, non-signal energy radiation also requires antennas. The antennas are generally reciprocal in that the same pair of antennas can be used as both transmit and receive antennas. The antenna conforms to the reciprocity theorem: the same antenna is the same as the basic characteristic parameter for transmission or reception.
In a conventional design, a wireless transmitting terminal, such as a wifi transmitting terminal, is used in a scenario that the wireless transmitting terminal is inserted into a computer or a television, and the wireless transmitting terminal can wirelessly transmit an audio signal of the computer or the television to a wireless headset, for example, the wireless headset is worn on a head of a person, and of course, the wireless headset can transmit the signal from the headset to the television or the computer through the wireless terminal. Conventional antennas therefore employ a separate dual antenna arrangement, including the following two approaches.
One is a flat type, as shown in fig. 1, two antenna components 101 are disposed on the substrate 200 in a flat manner, and this antenna layout occupies a large space, or has a small space utilization ratio, which results in that the length and width of the whole wireless terminal product are increased, resulting in unnecessary housing cost. More importantly, the tiled layout requires additional clearance on the substrate, also called the motherboard, otherwise the radiation capability of the antenna to the substrate in the direction away from the back, i.e. the back, is greatly reduced, and the flat layout causes the characteristics of the antenna to be degraded, wherein the characteristics of the antenna include, but are not limited to, radiation capability, transmission distance, sensitivity of receiving signals, and the like.
The other is vertical type, as shown in fig. 2, two antenna components 101 are arranged on a substrate 200 in a vertical manner, and the two antenna components 101 in the antenna layout are separated, and this design causes assembly to be particularly difficult when the wireless terminal is manufactured, because each antenna needs to be welded separately, which is time-consuming, and because the whole antenna still has a medium, the characteristics of the antenna are still not good enough, and the medium inevitably affects the transmission and reception of signals by the antenna.
It should be noted that, it is generally considered by those skilled in the art that the two antenna elements of the antenna should not be electrically connected, otherwise, the characteristics of the antenna are seriously affected, and the transmission and reception of signals cannot be realized; there is also a requirement for the spacing of the two antenna components, but in certain applications where minimal PCB space is required, the minimum distance between the two antenna components is typically less than half a wavelength in order to accommodate the smaller volume, and the closer the two antenna components are, the more they will interact.

In each embodiment of this application, directly couple together two antenna subassemblies of separation, be connected through coupling assembling between two antenna subassemblies, coupling assembling only plays mechanical connection's effect essentially, and the characteristic or the function to the antenna are nearly not had the influence, can even have the nonmetal substitution of mechanical connection ability. The connection component is necessary and indispensable because the two antennas are closer to each other and affect each other more. Further, it is most important that the first ground terminal of the first antenna component adjacent to the second antenna component and the second ground terminal of the second antenna component adjacent to the first antenna component are connected to the connection component, respectively. That is, the connecting component is connected to the ground terminals of the first antenna component and the second antenna component, respectively, and the ground terminal closest to the first antenna component and the second antenna component is connected to ensure that the connecting component does not become a part of the first antenna component or the second antenna component. That is, the connecting component must be connected between two grounding terminals, and two feeding terminals cannot be connected, which is necessary to ensure that the connecting part cannot be used as a part of the antenna, and the connecting part is used for mechanically connecting and fixing two antenna components, and simultaneously, the processing and welding are convenient. In one embodiment, the connecting member is made of the same material as the first antenna element and the second antenna element, and the connecting member is further used for separately and completely grounding. In such a design, the connecting component is also made of metal and is also grounded, and the connecting component is grounded separately relative to the first antenna component and the second antenna component, i.e. is grounded separately without depending on the first ground terminal and the second ground terminal, and further, the connecting component, the first ground terminal and the second ground terminal are respectively connected to different ground wires.

Further, in one embodiment, the abutting portion is soldered to the predetermined ground, a reflow process and the like may be used during production, and the antenna structure including the first antenna assembly, the second antenna assembly and the connecting assembly is soldered once, so as to improve production efficiency and save cost. In one embodiment, the first antenna assembly and the second antenna assembly are integrally formed with the connecting assembly. Like this integrated into one piece makes things convenient for the mould once only to dash out including coupling assembling and two antenna module's whole antennas, aims at and just can carry out reflow soldering after once, and welding efficiency improves greatly, and machining error is littleer, the processing of being more convenient for, and process velocity is faster. In this embodiment, the connecting component must be grounded because of metal, otherwise, the radiation characteristic of the antenna may be affected, such a design, on one hand, prevents the two antenna components of the antenna from interfering with each other through the connecting component, on the other hand, is beneficial to reducing the distance between the two antenna components, on the other hand, overcomes the technical prejudice that the two antenna components of the antenna should not be conductively connected by a person skilled in the art, and realizes effective transmission of wireless signals; in addition, in the embodiment, the connecting assembly and the two antenna assemblies can be integrally formed, so that the antenna structure can be rapidly processed and obtained, the rapid and automatic installation process of the antenna structure is facilitated, and the production efficiency is greatly improved. Moreover, because the first antenna assembly, the second antenna assembly and the connecting assembly are integrally formed, only one material is needed during production, the processing is more convenient, the processing speed is higher, the installation is also very convenient, meanwhile, the antenna is erected on the substrate, the characteristic is better, the space utilization rate is higher, and an independent clearance area does not need to be divided on the substrate.
In addition to being integrally formed, the connection assembly may be implemented in other manners, and in one embodiment, the connection assembly is plugged or clamped with the first antenna assembly and the second antenna assembly respectively. Further, in one embodiment, the connecting element is made of a material different from the materials of the first and second antenna elements, for example, a ceramic material or a plastic.
