Detailed Description
The present invention is further illustrated by the following examples, which are not to be construed as limiting the invention thereto.
Referring to fig. 1 and 2, the present embodiment provides a rotating antenna system disposed in a mobile wireless device (e.g., a notebook computer), the rotating antenna system including an angle rotator 11, a control unit 12, a high-gain antenna 13, and an operation unit 14. The angle rotator 11 carries a tray 111. The control unit 12 is connected to the angle rotator 11 and disposed at a side of the angle rotator 11, and is located at the control board 101 for controlling the 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 computing unit 14 is connected to the control unit 12, and controls the rotation angle of the angle rotator 11 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 generally connected to the wireless chip 2 of the 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 working modes (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 a plurality of working modes of the antenna body 131, and the mode information established by the operation unit 14 corresponds to the plurality of working modes of the antenna body 131.
Preferably, the angle rotator 11 is a stepping motor, which can change multiple horizontal angles of the high gain antenna 13 in the spatial orientation, and the finer the stepping motor is, the more angle divisions can be controlled. The antenna body 131 is, for example, a slot antenna, the antenna body 131 is erected on the tray 111, and it can be seen that the metal surface of the slot antenna is located on a substrate, and is usually fabricated 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 both planar and can be realized by using 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 axis of the stepping motor, and the antenna body 131 is farther from the axis of the stepping motor, so that the highest gain direction of the high-gain antenna 13 is a direction away from the rotation axis perpendicularly. It can be seen that the tray 111 is horizontally disposed, the highest gain direction is parallel to the horizontal plane, and the highest gain direction can be changed according to 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, that is, the maximum directivity is achieved, and the maximum gain is achieved in the direction away from the rotation axis. The structure of the antenna body 131 and the reflector 132 is not limited to this, and other structures may be substituted as long as the maximum gain in the direction away from the rotation axis is achieved. Preferably, the maximum gain is greater than 6dB, and the maximum gain is preferably between 6dB and 7dB in accordance with the adaptability of the antenna signal coverage and the mechanism for dynamically adjusting the angle rotator 11.
Specifically, the network card module of the mobile wireless device is connected to the rotating 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 a driving subsystem in the operation system of the mobile wireless device, the rotating antenna system can be an intelligent module, the algorithm of the operation unit 14 performs the optimal mode prediction (including the selection of the operating mode of the antenna body 131) of the high-gain antenna 13, and the rotating antenna system is made into a module and can be embedded 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 rotating antenna system of the intelligent module is implemented in cooperation, thereby achieving the purpose of dynamically detecting and selecting the antenna performance.
In summary, the rotary antenna system provided in the embodiments of the present invention realizes a single high-gain antenna, and the radiation direction can change along with 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 a high industrial application value.
