In the embodiment of the present invention, the wireless terminal is a device having a wireless transceiving function or a chip that can be disposed in the device. In practical applications, the wireless terminal in the embodiment of the present application may be a television, a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety, a wireless terminal in city (city), a wireless terminal in smart home (smart home), and the like. The embodiments of the present application do not limit the application scenarios. The device with the wireless transceiving function and the chip capable of being arranged in the device are collectively referred to as a wireless terminal in the present application.
Fig. 1 is a schematic structural diagram of a wireless terminal according to an embodiment of the present invention.
For convenience of explanation, fig. 1 shows only main components of the terminal-side apparatus. As shown in fig. 1, the wireless terminal 100 includes a processing module 101, a Front End Module (FEM) 102, an active guiding chip 103, an impedance transmission line 104, an antenna module 105, an input/output module 109, a memory module 110, and the like.
The processing module 101 is mainly used for controlling each module in the wireless terminal 100, processing data, and the like; the FEM102 is mainly responsible for processing communication protocols and communication data, and the FEM may support 802.11 series wireless protocols, and may also support mobile communication protocols, such as a New Radio (NR) system, a global system for mobile communications (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, an advanced long term evolution (LTE-a) system, a Universal Mobile Telecommunications System (UMTS), an evolved Long Term Evolution (LTE), and a future communication system.
The active boot chip 103 may receive an instruction of the processing module 101 and output the instruction to the corresponding module.
The main antenna 106, and the parasitic element 108, are primarily used for transceiving radio frequency signals in the form of electromagnetic waves. The details of the rf switch module 107 will be described later, and are not described herein again.
The storage module 110 is mainly used for storing software programs and data. The input/output module 109 may be a touch screen, a display screen, a keyboard, and the like, and is mainly used for receiving data input by a user and outputting data to the user.
In the embodiment of the present application, a specific structure of the rf switch module 107 can be referred to as shown in fig. 2. In fig. 2, the rf switch module 107 includes a switch and at least one channel, and the rf switch module 107 controls the channel to which the switch is electrically connected to switch the parasitic component 108 to a different channel. For any of the at least one channel, the channel includes a capacitance in series, and each of the at least one channel includes a capacitance of a different magnitude. For example, when the rf switch module 107 includes 4 channels, the capacitance of each channel in the 4 channels may be: 0.5pF, 1.2pF, 3.3pF, 6.8 pF.
It should be noted that, in the embodiment of the present application, the rf switch module 107 may also be directly connected to the active guiding chip 103 instead of being connected to the rf impedance transmission line 104, which is not described herein again.
In fig. 2, the main antenna 106 is physically close to the main body of the parasitic element 108 (especially the strongest radiation part), parallel or close to it without intersecting, so that it is easily coupled by the parasitic element 108 to form a change of radiation pattern from a free radiation pattern to a controlled directivity enhanced pattern.
The capacitance of each of the at least one channel may be between 0.5pF and 22 pF. Further, the capacitance of each via may be in 0402 package, where 04 denotes a length of 0.04 inches and 02 denotes a width of 0.02 inches. For example, the capacitor may be a stacked capacitor of the GRM series manufactured by village institute.
The antenna module 105 includes a main antenna 106, a radio frequency switch module 107, and a parasitic component 108 of the main antenna 106. Wherein the main antenna 106 is electrically connected to the FEM102 through the rf impedance transmission line 104, and the parasitic element 108 is electrically connected to the rf impedance transmission line 104 through the first channel electrically connected to the rf switch module 107; the first channel is a channel of at least one channel between the parasitic element 108 and the radio frequency switch module 107.
When the wireless terminal 100 is initially powered on, the processing module 101 may control the rf switch module 107 to switch from a first channel to a first at least one channel, and after each switching, obtain a signal indication value of a wireless signal, and obtain at least one signal indication value in total. The processing module 101 may determine the channel with the largest signal indication value as the first channel, so as to control the radio frequency switch module 107 to switch the switch in the radio frequency switch module 107 to the first channel.
In the embodiment of the present application, the main antenna 106 may be a conventional single-frequency antenna design, regardless of its form. The parasitic antenna is of a monopole or loop (loop) type design, parallel to and immediately adjacent to the main antenna 106, but not connected thereto.
For example, for the main antenna 106 receiving 2G signals, the length of the parasitic element 108 may be selected to be 10-20mm, the width of the parasitic element may be 0.5-2.0mm, and the parasitic element may be parallel to or closely adjacent to the main antenna 106 by 1mm-3mm, depending on the specific debugging effect.
The coupling current between the main antenna 106 and the parasitic element 108 is not the same through different devices (capacitance, inductance). Since the impedance of the whole antenna is changed by the variation of the devices on the switch, different radiation patterns can be generated.
In the embodiment of the present application, after the parasitic element 108 is introduced, the parasitic element 108 participates in forming the electrical characteristic of the main antenna 106 in a coupling manner, and forms an antenna radiation pattern; the different loading on parasitic element 108 will cause main antenna 106 to obtain different electrical characteristics and radiation patterns, and the electrical characteristics obtained on parasitic element 108 are significantly different in both open and short states, and the radiation patterns are also different. As for the parasitic component 108, when the series capacitors are electrically connected through the rf switch module 107, it generates electromagnetic waves to couple to the main antenna 106, so as to change the current characteristic distribution of the main antenna 106 and change the phase of the electromagnetic waves radiated by the main antenna 106, thereby participating in changing the main body distribution impedance of the main antenna 106 and changing the radiation pattern of the main antenna 106. Meanwhile, it acts as a far-field reflection arm, and the electromagnetic wave signal radiated by it also has the effect of amplitude modulation and phase modulation on the main antenna 106.
For example, the rf switch module 107 includes 4 channels, and the capacitance of each of the 4 channels is: 1.5pF, 3.3pF, 6.8pF, 12 pF. When the parasitic element 108 is electrically connected to the rf impedance transmission line 104 through the corresponding channel of the capacitor, the antenna radiation pattern of the main antenna 106 can be referred to as shown in fig. 3. As can be seen from fig. 3, when different capacitances are connected to the parasitic element 108, the main antenna 106 can obtain different signal gains in different directions by means of coupling.
Further optionally, the main antenna 106 body needs to have a wider bandwidth (e.g., ≧ 500MHz) during design, so as to ensure that the influence of the coupling variation generated by the parasitic component 108 on the main frequency of the main antenna 106 is within the application bandwidth range.
In this embodiment, the processing module 101 may be configured to detect a wireless signal received from the antenna module 105, and switch the radio frequency switch module 107 to a second channel when a signal indication value of the wireless signal is smaller than a threshold value, so that the parasitic component 108 is electrically connected to the radio frequency impedance transmission line 104 through the second channel; the second channel is a channel with a largest signal indication value of the corresponding wireless signal in the at least one channel.
Wherein, the signal indication value of the wireless signal may refer to any one of the following:
signal throughput;
spatial signal strength;
signal to noise ratio.
Further, the processing module 101 may send a control command to the rf switch module 107 by actively guiding the transmitter chip 103, so as to control the rf switch module 107 to switch channels. The processing module 101 and the active lead chip 103 communicate with each other through a General Purpose Input/Output (GPIO) interface.
The processing module 101 may transmit and receive data through the FEM102, or may perform carrier transmission communication directly through the antenna module 105.
The processing module 101 may actively trigger signal search when detecting that the location of the wireless terminal 100 changes or the spatial network environment changes, or when determining that a timing scanning period of a wireless signal of the wireless terminal 100 arrives, detect whether a signal indication value of the wireless signal is smaller than a threshold, and if the signal indication value is greater than or equal to the threshold, keep a channel currently selected by the radio frequency switch module 107 unchanged. If the signal intensity is less than the threshold value, the fast scanning is continued, and the state of the strongest mode of the wireless signal is confirmed, so that the mode switching is carried out and the connection is fixed. Specifically, the processing module 101 may respectively switch the radio frequency switch module 107 from a first channel to a first at least one channel of the at least one channel when the signal indication value of the wireless signal is smaller than the threshold value, so as to obtain at least one signal indication value; the processing module 101 determines a channel corresponding to a largest signal indication value among the at least one signal indication value as a second channel; finally, the rf switch module 107 is switched to the second channel.
Further, main antenna 106 may be extended to dual-band antenna applications, such as WiFi 2.4GHz +5GHz range applications.
Further, the wireless terminal 100 in the embodiment of the present application may support a 2-transmission-2-reception (2T2R) Multiple-Input Multiple-Output (MIMO) technology, a 4T4R MIMO technology, or the like.
When the wireless terminal 100 supports the 2T2R MIMO technology, it may include 2 communication modules, which may be specifically referred to as shown in fig. 4. In fig. 4, the wireless terminal 300 includes two antenna modules, an antenna module 305 and an antenna module 312. The wireless terminal 300 further includes a processing module 301, a FEM302, a FEM311, an active boot chip 303, an impedance transmission line 304, an impedance transmission line 316, an input-output module 309, a memory module 310, and the like. Other cases are not described in detail.
