Detailed Description
The invention is further illustrated, but is not limited, by the following examples.
Referring to fig. 1 and 2, the present embodiment provides a rotary antenna system disposed in a mobile wireless device (e.g. a notebook computer), the rotary antenna system includes an angle rotator 11, a control unit 12, a high gain antenna 13, and a computing unit 14. The angle rotator 11 carries a tray 111. The control unit 12 is connected to the angle rotator 11, and is disposed on a side surface of the angle rotator 11, in the figure, on the control board 101, for controlling a rotation angle of the angle rotator 11. The high gain antenna 13 is disposed on the tray 111, and the high gain antenna 13 includes an antenna body 131 and a reflector 132. The operation unit 14 is connected to the control unit 12, and the rotation angle of the angle rotator 11 is controlled by the control unit 12 according to the wireless data throughput of the mobile wireless device. Preferably, the operation unit 14 changes the rotation angle of the angle rotator 11 to 360 degrees, and continuously monitors the wireless data throughput of the mobile wireless device during the process to establish the mode information. The high gain antenna 13 is typically a wireless chip 2 connected to a mobile wireless device and is controlled by the wireless chip 2. The high gain antenna 13 may have a plurality of operation modes, which the wireless chip 2 controls. In another embodiment, the wireless chip 2 is not used for controlling the operation mode (the wireless chip 2 does not need to manage the antenna, and only uses the antenna as a passive component for receiving and transmitting wireless signals), but the control unit 12 controls the plurality of operation modes of the antenna body 131, and the mode information established by the operation unit 14 corresponds to the plurality of operation modes of the antenna body 131.
Preferably, the angle rotator 11 is a stepper motor that can change the multiple horizontal angles of the high gain antenna 13 in spatial orientation, with finer steps Ma Dayue, the more angle differences that can be controlled. The antenna body 131 is, for example, a slot antenna, where the antenna body 131 is erected on the tray 111, and the metal surface of the slot antenna is shown on a substrate, and is usually manufactured by etching. The reflector 132 is, for example, a half-wavelength reflector, and the reflector 132 has a half-wavelength slot, preferably also standing on the tray 111, and can be made by etching, so that the antenna body 131 and the reflector 132 are planar and can be realized by a low-cost circuit substrate.
Preferably, the distance between the reflector 132 and the rotation axis of the angle rotator 11 is smaller than the distance between the antenna body 131 and the rotation axis, that is, the reflector 132 is closer to the center of the tray 111 and closer to the stepping motor axis, and the antenna body 131 is farther from the stepping motor axis, so that the highest gain direction of the high gain antenna 13 is a direction perpendicular to the rotation axis from the rotation axis. As can be seen, the tray 111 is placed horizontally, the highest gain direction is parallel to the horizontal plane, and the highest gain direction can be changed with the rotation angle of the angle rotator 11. The distance between the antenna body 131 and the reflector 132 is adjusted so that the highest gain of the high gain antenna 13 is maximized, i.e., the directivity is maximized, and the highest gain is achieved in a direction away from the rotation axis. The structures of the antenna body 131 and the reflector 132 are not limited to this, and may be replaced by other structures as long as the maximum gain is achieved in the direction away from the rotation axis. Preferably, the maximum gain is greater than 6dB, and the gain is preferably between 6dB and 7dB in combination with the antenna signal coverage and the mechanical adaptability of the angle rotator 11 for dynamic adjustment.
Specifically, the network card module of the mobile wireless device is connected with the rotary antenna system provided in this embodiment, that is, the operation unit 14 is responsible for accessing the physical layer wireless data throughput of the network card module by the driving subsystem in the operating system of the mobile wireless device, the rotary antenna system can be an intelligent module, the algorithm of the operation unit 14 performs the best mode prediction (including the operation mode selection of the antenna body 131) of the high gain antenna 13, and the rotary antenna system is made into a module and can be built in the mobile wireless device, so that the mobile wireless device can have the function of changing the maximum gain of 360 degrees in the horizontal direction, and the rotary antenna system of the intelligent module is cooperatively realized to achieve the purpose of dynamically detecting and selecting the antenna performance.
In summary, the rotary antenna system provided by the embodiment of the invention realizes a single high-gain antenna, and the radiation direction can be changed according to the environment change of the mobile wireless device, so as to monitor the environment condition in real time to achieve the effect of maintaining stable high throughput, and has high industrial application value.
