Detailed Description
The technical solution of the present application will be specifically described below by way of examples with reference to the accompanying drawings. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
It should be noted that: in the present examples, "first", "second", etc. are used for distinguishing similar objects and are not necessarily used for describing a particular order or sequence.
The technical means described in the embodiments of the present application may be arbitrarily combined without conflict.
In the scene of the internet of things, terminal equipment is required to be capable of controlling a target object. For example, in some scenarios, when the terminal device points at or towards the target object, the terminal device displays a control interface for the target object, so that the terminal device can control the target object through the control interface. However, in implementation scenarios like this, the technician finds that the accuracy of the direction information of the target object determined by the terminal device relative to the terminal device is low, for example, in some scenarios, the terminal device does not face the target object in a real scenario, but the terminal device determines that the terminal device faces the target object, so that the display interface for controlling the target object is displayed erroneously, and in other scenarios, the terminal device faces the target object in a real scenario, but the terminal device determines that the terminal device does not face the target object, so that the display interface for controlling the target object is not displayed, or the display interface for controlling other devices is displayed. This may make it inconvenient for the user to control the target object using the terminal device.
In order to solve this problem, as a result of continuous research, the skilled person finds that, since the phase centers of at least two antennas in the terminal device for determining the direction information may not only affect each other, but also may be affected by the surrounding environment, the phase center of each of the at least two antennas may be shifted compared to the phase center in an isolated state, so that the accuracy of the direction information of the target object determined by the terminal device relative to the terminal device is low. Based on this research, the present application provides the following method of adjusting the antenna position.
Fig. 1 is a schematic flowchart of a method for adjusting an antenna position according to an embodiment of the present application, and as shown in fig. 1, the method is applied to an apparatus for adjusting an antenna position, and the method includes:

S102, adjusting the position of at least one antenna in the at least two antennas based on the phase centers of the at least two antennas.
In some embodiments, the position of at least one of the at least two antennas may be adjusted in the simulation environment. For example, the device for adjusting the antenna position may display at least two antennas on the display screen, and the user may adjust the position of at least one displayed antenna. For example, the user may drag the position of at least one antenna of the displayed at least two antennas through a mouse to change the position of the at least one antenna. For another example, the user may move the position of the at least one antenna up and down via the keyboard to cause the position of the at least one antenna to change. For another example, the user may slide the display screen or click certain buttons displayed on the display screen to change the position of at least one antenna.

The length direction of the terminal device may in other embodiments be referred to as the height direction of the terminal device. In some embodiments, the width direction of the terminal device may be a horizontal direction, and the length direction of the terminal device may be a vertical direction. In the embodiment of the present application, the width direction of the terminal device may be a direction of a shorter side of the front housing or the rear housing of the terminal device, and the length direction of the terminal device may be a direction of a longer side of the front housing or the rear housing of the terminal device.
For example, the phase centers of the at least two antennas may each be arranged in the width direction of the terminal device, or a projection in the length direction of a distance between any one of the phase centers of the at least two antennas to another phase center is smaller than or equal to the second threshold value. The second threshold may be determined based on a center frequency of either antenna.
For another example, the phase centers of the at least two antennas may be both arranged along the length direction of the terminal device, or a projection in the width direction of a distance from any one of the phase centers of the at least two antennas to another phase center is smaller than or equal to the second threshold.
For another example, a part of the phase centers of the at least two antennas may be arranged in the width direction of the terminal device, and another part of the phase centers of the at least two antennas may be arranged in the length direction of the terminal device, or a projection of a distance between any one of the phase centers of the one part and another phase center in the length direction is smaller than or equal to the second threshold, and a projection of a distance between any one of the phase centers of the another part and another phase center in the width direction is smaller than or equal to the second threshold.
In further embodiments, some of the at least two phase centers may be arranged along a target direction, wherein the target direction may be either a direction parallel to the front housing or the rear housing of the terminal device.
