All other embodiments, which can be derived from the embodiments given herein by one of ordinary skill in the art, are within the scope of the utility model.
In order to improve communication quality of a wireless communication device under different environments, the present application provides a wireless communication device, referring to fig. 1a, including:

During the communication process, the MCU sends a control signal to the tuning switch, so that each frequency modulation circuit in the tuning switch is sequentially communicated with the antenna, the antenna can respectively receive electromagnetic wave signals under different working frequency bands, and the MCU analyzes the electromagnetic wave signals under different working frequency bands to determine the electromagnetic wave signals with good communication quality; the working frequency band of the received electromagnetic wave signals with good communication quality is called a target working frequency band, the frequency modulation circuit enabling the antenna to work under the target working frequency band is called a target frequency modulation circuit, and the MCU sends a control signal to the tuning switch so that the target frequency modulation circuit in the tuning switch is communicated with the antenna, so that the antenna can work under the target working frequency band, namely, the wireless communication equipment can transmit information by using the electromagnetic wave signals with good communication quality.
The number of the frequency modulation circuits in each tuning switch can be set according to practical situations in a customized mode, and each tuning switch 12 comprises at least two frequency modulation circuits. Specifically, the number of frequency modulation circuits in each tuning switch may be 2, 3, 4, 5, or 8, etc. In an example, referring to fig. 1b, taking the tuning switch including four frequency modulation circuits of RF1, RF2, RF3, and RF4 as an example, the MCU may control the voltage inputs of the tuning switches V1, V2, and V3 to control the frequency modulation circuit connected to the antenna, and all three of V1, V2, and V3 may correspond to two states of voltage input and no voltage input, and theoretically may support the gating of six frequency modulation circuits, where VDD represents the operating voltage of the tuning switch, and ANT represents the antenna.
The wireless communication device of the embodiment of the present application is not limited to the one-to-one real-time communication shown in fig. 2a, for example, but may also be applied to a one-to-many (e.g., shown in fig. 2 b) or a many-to-many (e.g., shown in fig. 2 c) communication scenario.

The number of the antennas and the number of the tuning switches in the wireless communication equipment can be set according to actual conditions in a user-defined mode, and the number of the antennas and the number of the tuning switches can be one or more. In one example, the wireless communication device may include an antenna and a tuning switch, where the tuning switch includes at least two frequency modulation circuits, and the MCU controls the frequency modulation circuits in the tuning switch, which are connected to the antenna, so that when different frequency modulation circuits are connected to the antenna, the operating frequency bands of the antenna are different, thereby enabling the wireless communication device to operate in different frequency bands.

the MCU13 is configured to control the antenna 11 connected to the radio frequency switch 403, and the radio frequency switch 403 is configured to transmit a communication signal between the antenna 11 connected to the radio frequency switch 403 and the MCU 13.
In one example, during communication, the MCU sends communication data to the antenna through the transmission path via the rf switch for transmission, and the external device sends electromagnetic wave signals to the rf switch after being received by the antenna, and then to the MCU through the reception path. The MCU controls the radio frequency switch to gate one path of antenna, then sequentially gates each frequency modulation circuit of the tuning switch, so that the antenna works under different channels, and then the radio frequency switch gates the other path of antenna to repeat the operation until the gating of all working frequency bands of all the antennas is completed, so that electromagnetic wave signals of each antenna under each working frequency band are obtained, and the electromagnetic wave signal with the best communication quality is selected. In one example, polling among channels can be performed through the above process every time a packet of data is received, so as to ensure that the optimal channel is updated in real time along with environmental change, and thus, optimal wireless data transmission is realized.
In the embodiment of the application, the working antenna can be gated by using the radio frequency switch, and switching of the antennas with different working frequency bands is increased, so that the wireless communication equipment can work in more frequency bands, and the frequency band with the best communication quality can be selected conveniently to increase the communication quality.

The wireless communication device adopts a dual-antenna layout of a horizontally polarized spring antenna and a vertically polarized spring antenna to realize omnidirectional coverage, see fig. 5a and 5b, where fig. 5a is an H-plane directional pattern of the antenna of the wireless communication device in the embodiment of the present application, and compared with the horizontally polarized spring antenna 401 being an XOZ plane and the vertically polarized spring antenna 404 being an YOZ plane, it can be seen that the H-plane directional pattern of the two spring antennas is better in omnidirectional. Fig. 5b is an antenna E-plane directional diagram of the wireless communication device in the embodiment of the present application, and with respect to two antennas which are both XOY planes, it can be seen from fig. 5b that a blind area exists in the directional diagram of a single spring antenna affected by the PCB board, and the directional diagrams of the two antennas are complementary on the XOY planes, so as to form omnidirectional radiation, thereby further improving the communication quality of the wireless communication device. In an example, the return loss of the two-spring antenna of the wireless communication device according to the embodiment of the present application is as shown in fig. 6, which can be seen that the two-spring antenna has better electrical performance in the frequency band around 433 MHz.

In an example, an effect diagram of the switching of the operating frequency of the single antenna of the wireless communication device in the embodiment of the present application is shown in fig. 8, it can be seen that signal-to-noise ratios of signals in different operating frequency bands are different, and an operating frequency band with a large signal-to-noise ratio may be selected for communication.
