In the drawings and the following description, well-known structures and techniques are not shown in order to avoid unnecessarily obscuring the present invention.
With the development of mobile communication technology, mobile phones, PADs, notebook computers and the like gradually become indispensable electronic products in life, and most of the electronic products adopt a millimeter wave antenna system for communication. In the process of millimeter wave antenna system use, the inside component of electronic product can produce the heat, and the heat is piled up and can't be given off in inside, can influence electronic product's life, is unfavorable for millimeter wave antenna system's use. The embodiment of the invention provides a millimeter wave antenna system and aims to solve the technical problem.
In one aspect, a millimeter wave antenna system is provided, as shown in fig. 1, the system comprising: a plurality of heat dissipation elements 1 and a millimeter wave antenna array 2;
a plurality of radiating elements 1 are distributed at intervals;
at least one radiating element 1 in the plurality of radiating elements 1 is provided with a millimeter wave antenna array 2, or a part of the radiating element 1 is provided with the millimeter wave antenna array 2;
the millimeter wave antenna array 2 is used for receiving the oscillation signal and converting the oscillation signal into electromagnetic waves and then radiating the electromagnetic waves outwards.
The millimeter wave antenna system provided by the embodiment of the invention at least has the following beneficial effects:
according to the millimeter wave antenna system provided by the embodiment of the invention, the oscillating current is received through the millimeter wave antenna array 2, and is converted into the electromagnetic wave, and the electromagnetic wave radiates to the surrounding space in the form of the electromagnetic wave, so that the communication function of the application terminal connected with the millimeter wave antenna system is completed; the heat generated from the internal components of the application terminal is dissipated by the heat dissipating member 1. According to the antenna system provided by the embodiment of the invention, on one hand, the purpose of heat dissipation is achieved through the heat dissipation element 1, on the other hand, the usable space of the millimeter wave antenna array 2 is not influenced by arranging the millimeter wave antenna array 2 on the heat dissipation element 1, and the service performance of the millimeter wave array in the millimeter wave antenna system is improved.
The millimeter wave system provided by the embodiment of the present invention is further described below by way of optional embodiments.
The millimeter wave is electromagnetic wave with a millimeter wave wavelength of 1-10 mm, and is positioned in the overlapping wavelength range of microwave and far infrared wave, so that the millimeter wave has the characteristics of two spectrums; millimeter wave antennas may be used to radiate electromagnetic waves.
The heat radiating element 1 may be a heat sink in a terminal. It can be understood that, a plurality of heat sinks are distributed side by side at intervals to form a heat dissipation device of the terminal, and the millimeter wave antenna array 2 provided by the embodiment of the present invention may be located on the heat sinks. Because the performance of the terminal device is different, and the material of the heat dissipation fins is different, the heat dissipation performance is also different, so in the embodiment of the present invention, the millimeter wave antenna array 2 may be disposed on at least one heat dissipation fin of the plurality of heat dissipation fins, or the millimeter wave antenna array 2 may be disposed on a part of one heat dissipation fin. Therefore, the application range and the utilization rate of the antenna system are expanded. At least one of the plurality of fins may be selected from a parallel fin, an adjacent fin, or a spaced fin. As an example, the millimeter wave antenna array 2 may be disposed by alternately selecting a plurality of heat sinks from among the plurality of heat sinks, so that the heat dissipation efficiency may be improved, and the space of the antenna may not be occupied. The millimeter wave antenna array 2 may be provided on a part or the entire heat radiating element 1, depending on the energy consumption or functional use of the terminal device to which the antenna system is applied. As an example, the millimeter wave antenna array 2 may be distributed in a straight form on the heat sink.
In an alternative embodiment, referring to fig. 2, the millimeter wave antenna array 2 includes a signal receiving unit 21 and a radiating unit 22 connected to each other, and both the signal receiving unit 21 and the radiating unit 22 are located on the heat dissipation element 1.
The millimeter wave antenna system can receive high-intensity oscillation current, convert the oscillation current into electromagnetic waves and radiate the electromagnetic waves from the periphery, so that the aim of signal transmission and communication is fulfilled. Therefore, in the embodiment of the present invention, the signal receiving unit 21 receives the oscillation current signal, and transmits the oscillation current signal to the radiation unit 22, and the radiation unit 22 converts the oscillation current signal into an electromagnetic wave, and radiates the electromagnetic wave to the surroundings through the radiation unit 22, thereby completing communication of the terminal device. The signal receiving unit 21 and the radiating unit 22 are connected in a telecommunication connection or a wireless communication connection, and both the signal receiving unit 21 and the radiating unit 22 are connected with the heat dissipation element 1.
In an alternative embodiment, the signal receiving unit 21 includes a plurality of power division and phase shift nodes 211, and the plurality of power division and phase shift nodes 211 are connected to the antenna element 221.
The power division and phase shift refers to dividing one path of input signal energy into two or more paths of output equal or unequal energy. The power division and phase shift functions can be realized by the power division power device. In the embodiment of the present invention, the power division phase shift node 211 is arranged, so that the signal received by the signal receiving unit 21 can be divided into two or more paths of energy for multi-path transmission, thereby improving the efficiency of signal transmission. As an example, the number of the power division and phase shift nodes 211 may be determined according to a capacity of a signal to be transmitted, and for example, when the capacity of the signal to be transmitted is large, the number of the power division and phase shift nodes 211 may be multiple, so as to ensure normal transmission of the signal. When the capacity of the transmission signal is small, the number of the power division phase shift nodes 211 can be small, so as to reduce the manufacturing cost of the system. The power division phase shift node 211 is connected to the power division power divider, so that phase shift splitting of signals can be realized. The power dividing phase shift node 211 and the power dividing power device may be electrically connected.
In an alternative embodiment, the signal receiving unit 21 further comprises a feeder line 212, the feeder line 212 being connected to the plurality of power dividing phase shifting connection points.
The feeder 212 provided by embodiments of the present invention may be a coaxial feeder 212, as an example, by feeding a current signal to the system through the feeder 212. The coaxial line is a guided system formed by two coaxial cylindrical conductors, and a broadband microwave transmission line in which air or a high-frequency medium is filled between an inner conductor and an outer conductor. The coaxial feed line 212 is adopted, the feed point can be selected at any position in the patch, and the influence on the antenna radiation is avoided; and the coaxial feeder 212 has small cable loss and strong anti-interference performance.
In an alternative embodiment, the radiating element 22 comprises at least two antenna elements 221, and the at least two antenna elements 221 are connected to the heat dissipating element 1.
The antenna element 221 is the most basic unit of an antenna. When an alternating current flows on the wire, electromagnetic wave radiation may occur at the antenna element 221. That is, the oscillation current signal is received by the signal receiving unit 21, power-divided and phase-shifted, and then radiated to the outside through the antenna element 221. It should be noted that the radiation unit 22 needs to receive and convert the oscillation current signal received by the signal receiving unit 21, and the signal receiving unit 21 has at least two paths of signals after being phase-shifted through power division, so that at least two antenna elements 221 need to be connected to the signal port to complete signal reception. The number of radiating elements 22 may be determined by the number of signals after power division and phase shifting. As shown in fig. 2, the embodiment of the present invention provides an example that the number of the power division phase shift nodes 211 is 4, and in this case, 4 antenna elements 221 are required to receive the current signal. As an example, the number of the power division phase shift nodes 211 may be 2, and in this case, the number of the required antenna elements 221 is also 2. The number of the antenna elements 221 in the embodiment of the present invention is not limited thereto.
In an optional embodiment, the millimeter wave antenna system further includes a connection base plate 3, and the connection base plate 3 connects the millimeter wave antenna array 2 to the heat dissipation element 1.
The bottom end of the connecting bottom plate 3 is connected with the heat radiating element 1, and the millimeter wave antenna system is fixed with the heat radiating element 1 through the connecting bottom plate 3. The bottom end of the connecting bottom plate 3 is connected with the heat radiating element 1, one surface of the connecting bottom plate 3 is connected with a radiation unit 22, and the other surface is connected with a signal receiving unit 21. Furthermore, one surface of the connection substrate 3 is connected to the antenna element 221, and the other surface is provided with a power division phase shift node 211, and the power division phase shift node 211 is connected to the feeder line 212. It should be noted that the connecting substrate 3 may reflect electromagnetic waves, that is, the feeder line 212 receives an oscillating current signal, the oscillating current signal is split by a power splitter and then reflected to the antenna element 221 on the other side of the connecting substrate 3 through the connecting substrate 3, and further the radiation of the electromagnetic wave signal is completed through the antenna element 221. As an example, the material of the connection substrate 3 may be copper. The length of the connecting bottom plate 3 can be determined according to the number of signal paths requiring power division and phase shift, and when the number of signal paths requiring power division and phase shift is large, a long connecting bottom plate 3 is required. When an excessive number of signals are not required, an excessive number of antenna elements 221 are not required, i.e., the length of the connection substrate 3 can be short, which saves costs when achieving the purpose of reflecting electromagnetic waves.
It should be noted that the heat dissipation element 1 provided in the embodiment of the present invention includes a plurality of heat dissipation fins and a heat dissipation bottom plate, and the plurality of heat dissipation fins are disposed on the heat dissipation bottom plate at intervals, so that the bottom end of the connection bottom plate 3 provided in the embodiment of the present invention is connected to the heat dissipation bottom plate, and when a millimeter wave antenna array 2 needs to be disposed at a certain heat dissipation fin position, the heat dissipation fin at the position is omitted and replaced with the millimeter wave antenna array 2.
In an alternative embodiment, the radiating element 22 further comprises a plurality of connection contacts, by means of which the antenna element 221 is connected with the connection backplane 3.
Each antenna element 221 has a plurality of connection contacts, via which the antenna element 221 is connected to the connection base plate 3. Furthermore, the connecting bottom plate 3 is provided with a connecting hole matched with the connecting contact, and the connecting bottom plate 3 is connected with the antenna array through the connecting hole and the connecting contact. The number of the connecting contacts can be determined according to the length of the connecting base plate 3, for example, when the length of the connecting base plate 3 is longer, the number of the connecting contacts can be larger, so that the connection stability of the connecting base plate and the heat dissipation base plate can be ensured. It should be noted that the antenna element 221 provided in the embodiment of the present invention has the connection contact, and the antenna element 221 is connected to the phase shift node 211 through the connection contact.
In an alternative embodiment, referring to fig. 3, the antenna element 221 includes a radiating element 2211 and a support 2212 connected, and the support 2212 is connected to the connection base 3.
The shape of the radiating element 2211 can be a diamond-shaped radiating element 2211 as shown in fig. 3, and can also be a positive direction, a triangle or a rectangle. The radiating element 2211 adopts a millimeter wave radiating element 2211 and has a high radiation broadband. The support 2212 may be made of metal, and the support 2212 may be a rectangular support rod. In the embodiment of the present invention, by controlling the metal support 2212, the impedance of the antenna element 221 can be controlled, so that the frequency band radiated by the millimeter wave antenna system is in a high impedance state at the bottom of the antenna element 221. The radiating element 2211 and the support 2212 may be fixedly connected, for example, welded or integrally formed by punching, to reduce the impedance of the support 2212.
In an optional implementation manner, the millimeter wave antenna system further includes a power division phase shift connection point, and the power division phase shift connection point is connected to the plurality of power division phase shift nodes 211.
It can be understood that when feeder 212 delivers the current signal to power division phase shift node 211, it is necessary to ensure that multiple power division phase shift nodes 211 are connected when splitting is performed through power division phase shift node 211, so as to ensure stable output of the signal. Therefore, in the embodiment of the present invention, a plurality of power division phase shift nodes 211 are connected by setting a plurality of power division phase shift connection points.
