AUTO ORIENTATING ANTENNA DEVICE

BACKGROUND OF THE INVENTION
1. Field of the Invention

The present disclosure relates to an antenna device, and, more particularly, to an auto orientating antenna device.

2. Description of Related Art

With the development of technology, 5G (5th generation mobile network) has become a main technology of wireless communication, and various 5G antenna devices, such as routers and Wi-Fi sharers, have also been manufactured. Since 5G antenna units need to operate in an ultra-high frequency band, such as 24 GHz, the size of the 5G antenna units need to be smaller than that of the prior arts (such as 4G antenna units), and thus 5G antenna units are more sensitive to the environmental interference. Therefore, the 5G antenna units need to be orientated to face a correct receiving direction.

However, since an antenna device needs to be connected to a power supply, the arrangement of the antenna device may be limited to the location of the power supply outlet in the house, and thus it may be difficult for a user to arrange the antenna device to face the correct receiving direction corresponding to enough signal strength. A good signal transmission cannot be realized without the correct receiving direction.

Therefore, it is desirable to provide an improved antenna device to mitigate and/or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

The object of the present disclosure is to provide an auto orientating antenna device capable of automatically facing a suitable receiving direction.

To achieve the object, the auto orientating antenna device of the present disclosure comprises a base, a body, and a processing chip. The base comprises a motor comprising a rotating shaft. The body is connected to the rotating shaft, and the body comprises at least one 5G (5th generation mobile network) antenna unit. The processing chip generates an auto orientating instruction according to at least one signal receiving status of the antenna unit, wherein the motor drives the rotating shaft according to the auto orientating instruction, so as to let the antenna unit face a receiving direction. Thus, the auto orientating antenna device can rotate automatically to face a suitable receiving direction according the signal receiving status.

In an embodiment, the body of the auto orientating antenna device comprises an inner case having an inner case side part, and the inner case side part has a plurality of holes formed thereon.

Furthermore, the auto orientating antenna device may comprise an outer case disposed outside the inner case side part, wherein the outer case has a plurality of slots formed thereon. Or, the auto orientating antenna device may comprise an outer case disposed outside the inner case side part, wherein the outer case is a spiral structure. Or, the auto orientating antenna device may comprise a removable outer case disposed outside the inner case side part.

In an embodiment, the signal receiving status is defined as the strength (typically, the amplitude) of a signal received by the antenna unit in a receiving direction.

Furthermore, the processor can calculate the strengths of the signals received by the antenna unit in different receiving directions, and find a receiving direction corresponding to the maximum strength of the signal, and the motor can rotate the rotating shaft to let the antenna unit face the receiving direction corresponding to maximum strength of the signal. Or, the processing chip can calculate the strength of the signal received by the antenna unit in at least one receiving direction, and find a receiving direction corresponding to the strength of the signal greater than or equal to a predetermined value, and the motor can drive the rotating shaft to let the antenna unit face the receiving direction corresponding to the strength of the signal greater than or equal to the predetermined value.

In an embodiment, a maximum rotating degree of the rotating shaft is 175 degree in clockwise direction or in counterclockwise direction.

Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

In the embodiment of FIG. 5(A), the body 20 is configured to rotate about “one turn” (or about “one circle”) in clockwise direction or in counterclockwise direction. In one embodiment, the term “one turn” is defined as the rotating angle is 350 degrees (that is, the maximum rotating angle may be 350 degree) with an error value within 0 to 30 degrees. That is, the maximum rotating angle may be in a range between 320 and 360 degrees, but not limited thereto. Thereby, when the body 20 completes the rotation once, the antenna unit 22 can receive the signal in each receiving direction, and each strength of each signal in each receiving direction can be detected by the processing chip 30.

In the embodiment of FIG. 5(B), the body 20 is configured to rotate an angle in clockwise direction and in counterclockwise direction. In an embodiment, the angle in clockwise direction and the angle in counterclockwise direction may be 175 degree, respectively (that is, the maximum rotating angle may be 175 degree in the respective directions) with an error value within 0 to 30 degrees. That is, the maximum rotating angle may be in a range between 145 and 180 degrees in the respective directions, but not limited thereto. Thereby, when the body 20 completes the rotations in clockwise direction and counterclockwise direction once, the antenna unit 22 can receive the signal in each receiving direction, and each strength of each signal in each receiving directions can be detected by the processing chip 30.

By the aforementioned rotation types and an auto orientating procedure executed by the processing chip 30 and the control chip 40, the auto orientating antenna device 1 can automatically face a receiving direction corresponding to better signal strength.

The details of the auto orientating procedure are described as follows. FIG. 6(A) is a flowchart of the steps of the auto orientating procedure according to a first embodiment of the present disclosure, and FIG. 6(B) is a flowchart of the steps of the auto orientating procedure according to a second embodiment of the present disclosure. References to FIG. 6(A) or 6(B) may be made with FIGS. 1 to 5(B), but not limited thereto.

In the embodiment of FIG. 6(A), the step S11 is executed in a way that the processing chip 30 starts the auto orientating procedure. The step S12 is executed in a way that the controlling chip 40 controls the motor 12 to drive the rotating shaft 120, so as to let the body 20 to rotate with respect to the base 10, and the antenna unit 22 receives the signals in different receiving directions. The step S13 is executed in a way that when the rotation of the body 20 is done, the processing chip 30 compares the strengths of the signals received by the antenna unit 22 in respective receiving directions, and finds the a receiving direction corresponding to maximum strength of the signal (called a “first receiving direction”). The step S14 is executed in a way that the processing chip 30 transmits the auto orientating instruction S1 to the controlling chip 40 according to the first receiving direction. The step S15 is executed in a way that the controlling chip 40 controls the motor 12 to drive the rotating shaft 120, so as to let the antenna unit 22 to face the first receiving direction. In this way, the auto orientating antenna device 1 can face the receiving direction with maximum signal strength automatically.

Regarding the step S11, in an embodiment, the processing chip 30 can determine whether to start the auto orientating procedure according to a predetermined condition, for example, when the power of the auto orientating antenna device 1 is turned on, or the signal strength of the current receiving direction is lower than a threshold, or the auto orientating procedure is started at specific time point, etc., but not limited thereto.

Regarding the step S12, in an embodiment, when the auto orientating procedure is started, the antenna unit 22 receives the signal in each receiving direction, and transmits the signal receiving status of each receiving direction to the processing chip 30. In an embodiment, an interval between two adjacent receiving directions is in a range between 5 to 10 degrees, but not limited thereto.

Regarding the steps S13, S14, and S15, in an embodiment, when the first receiving direction corresponding to the maximum signal strength is found by the processing chip 30, the processing chip 30 can calculates a distance between a current receiving direction of the antenna unit 22 and the first receiving direction, and then generate the auto orientating instruction S1 according to the distance, which means that, the auto orientating instruction S1 can comprise an information of an angle difference between the current receiving direction and the first receiving direction. In an embodiment, the angle difference may be 0 degree. In this way, the controlling chip 40 can adjust the receiving direction of the antenna unit 22 according to the auto orientating instruction S1.

Accordingly, in the first embodiment of the auto orientating procedure, the auto orientating antenna device 1 can face the direction corresponding to maximum signal strength automatically.

In the embodiment of FIG. 6(B), the step S21 is executed in a way that the processing chip 30 starts the auto orientating procedure. The step S22 is executed in a way that the controlling chip 40 controls the motor 12 to drive the rotating shaft 120, so as to let the body 20 rotate with respect to the base 10, and the antenna unit 12 receives the signal in different receiving directions. The step S23 is executed in a way that during the rotation of the body 20, the processing chip 30 calculates the strength of the signal received by the antenna unit 22 in the current receiving direction, and determines whether the strength of the signal in the current receiving direction is greater than or equal to a predetermined value. When the signal strength in the current receiving direction is not greater than or equal to the predetermined value, the step S23 keeps being executed (i.e. the rotation continues). When the signal strength in the current receiving direction is greater than or equal to the predetermined value, the step S24 is executed, wherein the processing chip 30 transmits the auto orientating instruction S1 to the controlling chip 40 according to the current receiving direction (called a “second receiving direction”). The step S25 is executed in a way that the controlling chip 40 controls the motor 12 to drive or stop the rotating shaft 120, so as to let the antenna unit 22 face the second receiving direction. In this way, the auto orientating antenna device 1 can face the receiving direction with suitable signal strength automatically.

The step S21 may be applied similarly to the description for the step S11, so the detailed description therefor is deemed unnecessary.

Regarding the steps S22 to S25, the processing chip 30 may compare the signal strength in current receiving direction with a predetermined value instantly during the rotation of the body 20. When the signal strength in current receiving direction is greater than or equal to the predetermined value, it means that the signal strength is enough, so the processing chip 30 will transmit the auto orientating instruction S1 to the control chip 40 to stop the operation of the motor 12. In an embodiment, the predetermined value may be adjusted at any time. In an embodiment, if the antenna unit 22 has deviated from the second receiving direction, the auto orientating instruction S1 may comprise a controlling instruction for adjusting the receiving direction of the body 20, which controls the motor 12 to drive the rotation of the rotating shaft 120.

Accordingly, in the second embodiment of the auto orientating procedure, the auto orientating antenna device 1 can face a receiving direction with signal strength satisfying the predetermined value.

In this way, the present disclosure can solve the conventional problem, and the user can place the auto orientating antenna device 1 at any location, and the body 20 of the auto orientating antenna 1 can face a suitable receiving direction automatically.

Although the present disclosure has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
