Technical Field

The present application relates to the field of communications technologies, and in particular, to an electronic device.

Background

Currently, an Ultra Wide Band (UWB) technology is a short-distance wireless communication mode, and a transmission distance thereof is usually within 10m, and a bandwidth of 1GHz or more is used. UWB technology does not use sinusoidal carriers, but rather uses narrow pulses of non-sinusoidal waves on the order of nanoseconds to microseconds to transmit data, and thus occupies a wide spectrum. The UWB technology has the advantages of low system complexity, low power spectral density of transmitted signals, insensitivity to channel fading, low interception capability, high positioning accuracy and the like, and is suitable for high-speed and short-distance wireless personal communication. Angle of Arrival (AOA) is a key parameter in UWB technology. For an antenna assembly, an Angle of Arrival (AOA) is generally obtained based on a Phase Difference of Arrival (PDOA) of an electromagnetic wave signal reaching two antennas in an electronic device. In the related art, the PDOA measurement values are different due to the difference in the posture of the electronic device during the use of the electronic device by the user, that is, the PDOA does not converge. The non-convergence of PDOA will result in inaccurate results when AOA calculations are performed using PDOA. The inaccurate AOA result can cause the inaccurate positioning result when the antenna in the electronic equipment is used for positioning, and the like.

The radiation aperture of the fourth antenna 140 is perpendicular to the direction in which the first region 101 and the second region 102 are arranged, and faces away from the third antenna 130.

In an embodiment, the electronic device 1 further includes a protection cover 70, and the protection cover 70 is at least partially sleeved on the outside of the battery cover 60 and used for protecting the battery cover 60. It is to be understood that, in the schematic diagram of the present embodiment, the electronic device 1 is illustrated as including the protective cover 70, and in other embodiments, the electronic device 1 may not include the protective cover 70.

It should be understood that the above description of the structure of the electronic device 1 is only a description of one form of the structure of the electronic device 1, and should not be understood as a limitation on the electronic device 1, nor should it be understood as a limitation on the antenna assembly 10.

In the electronic device 1 of the related art (see the above description), the battery cover 60 and the protective cover 70 have an effect on electromagnetic wave signals transmitted and received by the respective antennas in the electronic device 1. Parameters such as the thickness and dielectric constant of the battery cover 60 and the protective cover 70 affect the surface wave modes (TE mode and TM mode) of the supported electromagnetic wave signal. The surface wave mode of the electromagnetic wave signal supported by the battery cover 60 and the protective cover 70 affects the PDOA of the electronic device 1. It can be seen that the PDOA of the electronic device 1 in the related art is influenced by the thickness and dielectric constant of the battery cover 60 and the protection cover 70.

In one embodiment, when the electronic device 1 is at the same pitch angle, the electronic device 1 has a first PDOA when transmitting and receiving electromagnetic wave signals in a predetermined frequency band and a predetermined direction. The electronic device 1 further includes a cover 67, wherein the cover 67 includes at least one of a battery cover 60 and the protective cover 70, the cover 67 is penetrated by electromagnetic wave signals transmitted and received by the electronic device 1 and the electronic device 1, and a second PDOA exists when the electronic device 1 transmits and receives electromagnetic wave signals in a predetermined frequency band and a predetermined direction and penetrates the cover 67, wherein a difference between the first PDOA and the second PDOA is within a first predetermined range.

It should be noted that, when the electronic device 1 includes the first antenna 110 and the second antenna 120, the electronic device 1 herein receiving and transmitting the electromagnetic wave signals in the predetermined frequency band and the predetermined direction means that at least one of the first antenna 110 and the second antenna 120 in the electronic device 1 receives and transmits the electromagnetic wave signals in the predetermined frequency band and the predetermined direction. When the electronic device 1 includes the first antenna 110, the second antenna 120, the third antenna 130 and the fourth antenna 140, the electronic device 1 herein receiving and transmitting the electromagnetic wave signals in the predetermined frequency band and the predetermined direction means that at least one of the first antenna 110, the second antenna 120, the third antenna 130 and the fourth antenna 140 in the electronic device 1 receives and transmits the electromagnetic wave signals in the predetermined frequency band and the predetermined direction.

The elevation angle may be, but is not limited to, 45 °, or 0 °, or 90 °, etc. The pitch angle may be any number of degrees, and the pitch angle is only used to describe the difference between PDOA when the electronic device 1 is not covered by the cover 67 and PDOA when the electronic device 1 is covered by the cover 67 when the electronic device 1 is at the same pitch angle.

When the electronic device 1 is not covered by the cover 67, the electronic device 1 has a first PDO1 when receiving and transmitting electromagnetic wave signals in a predetermined frequency band and a predetermined direction. It should be noted that the covering referred to herein includes a direct contact covering and a covering spaced apart from each other. Since the electronic device 1 is not covered by the cover 67, the electronic device 1 does not pass through the cover 67 when receiving and transmitting electromagnetic wave signals of a preset frequency band and electromagnetic wave signals of a preset direction.

The electromagnetic wave signals transceived by the electronic device 1 have a second PDOA when penetrating the cover 67. The difference between the first PDOA and the second PDOA is within a first predetermined range, which means that the difference between the first PDOA and the second PDOA is small or even zero.

In an embodiment, when the electronic device 1 is at the first pitch angle, the electronic device 1 has a first PDOA when receiving and transmitting electromagnetic wave signals in a predetermined frequency band and a predetermined direction. When the electronic device 1 is at the second pitch angle, the antenna has a second PDOA when receiving and transmitting electromagnetic wave signals in the preset frequency band and the preset direction. Wherein the first pitch angle is not equal to the second pitch angle, and a difference between the first PDOA and the second PDOA is within a second preset range.

In this embodiment, the difference between the first PDOA and the second PDOA is within a second predetermined range, which means that the difference between the first PDOA and the second PDOA is small or even zero, indicating that the angle difference between the PDOAs of the electronic device 1 is small when the electronic device 1 is at different pitch angles.

It is understood that the values of the first PDOA in this embodiment and the first PDOA in the previous embodiment may be the same or different; the second PDOA in this embodiment may have the same or different value as the second PDOA in the previous embodiment.
