[0063] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be described in more detail below with reference to the drawings.

[0064] In combination with Figure 1 and Figure 2 The embodiment provides an electronic device, which comprises a device main body 100, a rear camera cover plate 200 and an antenna assembly 300.

[0065] The rear camera cover plate 200 is located on the back of the device main body 100, and the antenna assembly 300 is located on the rear camera cover plate 200; the antenna assembly 300 comprises a first radiation branch 1 and a second radiation branch 2, the first radiation branch 1 and the second radiation branch 2 are connected vertically, and a first connecting point 3 of the first radiation branch 1 and the second radiation branch 2 is grounded.

[0066] ​The first radiation branch 1 is provided with a first feeding point 11, and the second radiation branch 2 is provided with a second feeding point 21, and the feeding signals of the first feeding point 11 and the second feeding point 21 have a phase difference of 90 degrees.

[0067] The electronic device of the embodiment is arranged with the antenna assembly 300 in the rear camera cover plate 200, the first radiation branch 1 and the second radiation branch 2 in the antenna assembly 300 are connected vertically, and the first radiation branch 1 and the second radiation branch 2 can respectively input the feeding signals with a phase difference of 90 degrees through the first feeding point 11 and the second feeding point 21, so as to excite to generate circularly polarized electromagnetic waves, which are beneficial to improve the satellite communication quality and the satellite communication performance of the terminal device; in addition, the antenna assembly 300 is located in the rear camera cover plate 200 of the terminal device and faces the back of the device body, so that a better clearance environment is obtained and the mutual interference between the antenna and other antennas in the electronic device is smaller.

[0068] In the embodiment, the first radiation branch 1 and the second radiation branch 2 form a circularly polarized antenna. The circularly polarized antenna is a special antenna, and the end trajectory of the electromagnetic wave electric field vector emitted or received by the circularly polarized antenna rotates in a circular or elliptical shape. The circularly polarized antenna has two signals with equal amplitude and orthogonal phase (a phase difference of 90 degrees), and through a specific structure and feeding mode, the two signals are superimposed in space, thereby generating a circularly polarized wave.

[0069] In a complex environment such as a city canyon, an indoor environment, etc., the signal will undergo multiple reflections and refractions, resulting in a change in polarization direction. The circularly polarized antenna can receive signals of any polarization direction, reducing polarization mismatch loss and effectively improving the stability and reliability of signal reception.

[0070] The circularly polarized antenna uniformly radiates energy in different directions, has a wide signal coverage range, and is suitable for scenes that require omnidirectional coverage, such as satellite communication, mobile communication base stations, etc.

[0071] Compared with a linearly polarized antenna, the circularly polarized antenna has a lower requirement for the directivity of the receiving antenna, enhancing the flexibility and reliability of the system. In some application scenarios that are difficult to accurately align the antenna, such as emergency rescue, military operations, etc., the circularly polarized antenna performs well due to this characteristic.

[0072] Circularly polarized waves have small attenuation under adverse weather conditions such as rain, fog, and snow, strong penetration of the ionosphere, and are not affected by the Faraday effect generated by the earth's polar magnetic field, so they have important application value in the field of satellite communication, etc.

[0075] Through the above arrangement, the first radiating branch 1 can form a working current perpendicular to the second radiating branch 2 to generate a circularly polarized electromagnetic wave.

[0076] In combination Figure 2 As shown in some embodiments, the antenna assembly 300 further includes a first feed source 7, which is electrically connected to the first feeding point 11 through a first feeding circuit 71 and is electrically connected to the second feeding point 21 through a second feeding circuit 72; wherein the difference between the conductive lengths of the first feeding circuit 71 and the second feeding circuit 72 is equal to one quarter of the target wavelength.

[0077] Through the above arrangement, the first feed source 7 can output a 90-degree phase difference feeding signal to the first radiating branch 1 and the second radiating branch 2 through the first feeding circuit 71 and the second feeding circuit 72 respectively, so as to realize the circularly polarized signal feeding of the antenna assembly 300.

[0081] The third radiating branch 4 is provided with a third feeding point 41, and the fourth radiating branch 5 is provided with a fourth feeding point 51, and the feeding signals of the third feeding point 41 and the fourth feeding point 51 have a phase difference of 90 degrees.

[0082] In this embodiment, the antenna assembly 300 further comprises a third radiating branch 4 and a fourth radiating branch 5 connected vertically, and the third radiating branch 4 and the fourth radiating branch 5 can respectively input feeding signals with a phase difference of 90 degrees through the third feeding point 41 and the fourth feeding point 51, and can stimulate another circularly polarized electromagnetic wave, which can provide satellite communication services for electronic devices together with the circularly polarized electromagnetic wave formed by the first radiating branch 1 and the second radiating branch 2.

[0083] In some possible implementations, the first radiating branch 1 and the second radiating branch 2 can stimulate left-handed circularly polarized electromagnetic waves, and the third radiating branch 4 and the fourth radiating branch 5 can stimulate right-handed circularly polarized electromagnetic waves.

[0084] Exemplarily, the antenna assembly 300 adopts a left-handed circularly polarized antenna as a transmitting antenna.

[0085] Another exemplarily, the antenna assembly 300 adopts a right-handed circularly polarized antenna as a receiving antenna.

[0086] The antenna assembly 300 of this embodiment can utilize the characteristics that left-handed circular polarization and right-handed circular polarization are isolated from each other, and can simultaneously transmit two different signals in the same frequency band, thereby doubling the satellite communication capacity.

[0087] In combination Figure 3 As shown, in some embodiments, the third radiating branch 4 comprises a fifth end 401 and a sixth end 402, and the fourth radiating branch 5 comprises a seventh end 501 and an eighth end 502; the fifth end 401 and the seventh end 501 are connected vertically at the second connection point 6; the third feeding point 41 is located between the fifth end 401 and the sixth end 402, and the fourth feeding point 51 is located between the seventh end 501 and the eighth end 502.

[0088] Through the above arrangement, the third radiating branch 4 can form working currents perpendicular to the fourth radiating branch 5 to generate circularly polarized electromagnetic waves.

[0089] In combination Figure 3As shown, in some embodiments, the antenna assembly 300 further comprises a second feed source 8, which is electrically connected with the third feeding point 41 through a third feeding circuit 81 and electrically connected with the fourth feeding point 51 through a fourth feeding circuit 82; wherein the difference between the conductive lengths of the third feeding circuit 81 and the fourth feeding circuit 82 is equal to one quarter of the target wavelength.

[0090] Through the above arrangement, the second feed source 8 can output the feeding signals with a phase difference of 90 degrees to the third radiation branch 4 and the fourth radiation branch 5 through the third feeding circuit 81 and the fourth feeding circuit 82 respectively, so as to realize the circularly polarized signal feeding of the antenna assembly 300.

[0091] In combination Figure 4 As shown, in some embodiments, the rear camera cover plate 200 is rectangular, and the first radiation branch 1 and the second radiation branch 2 are respectively arranged on two adjacent edges of the rear camera cover plate 200.

[0092] Through the above arrangement, the first radiation branch 1 and the second radiation branch 2 can be connected perpendicularly to each other, and the first connection point 3 is located at the intersection of the adjacent edges of the rear camera cover plate 200.

[0093] In combination Figure 4 As shown, in some embodiments, when the antenna assembly 300 further comprises the third radiation branch 4 and the fourth radiation branch 5, and the third radiation branch 4 and the fourth radiation branch 5 are connected perpendicularly to the second connection point 6, the third radiation branch 4 and the fourth radiation branch 5 are respectively arranged on the other two adjacent edges of the rear camera cover plate 200.

[0094] Wherein, the first connection point 3 and the second connection point 6 are respectively located at opposite ends of the same diagonal of the rear camera cover plate 200.

[0095] Through the above arrangement, the four radiation branches of the antenna assembly 300 can be respectively arranged on the four edges of the rear camera cover plate 200, on the one hand, the first radiation branch 1 and the second radiation branch 2 can be connected perpendicularly to each other, and the third radiation branch 4 and the fourth radiation branch 5 can be connected perpendicularly to each other, so as to meet the respective circularly polarized radiation requirements, on the other hand, the space of the rear camera cover plate 200 can be fully utilized, and the functional modules (such as cameras and the like) in the middle of the rear camera cover plate 200 will not be interfered. In addition, on the rectangular rear camera cover plate 200, after the four radiation branches are respectively arranged on the four edges of the rear camera cover plate 200, the circularly polarized antenna formed by two of the radiation branches is opposite to the other circularly polarized antenna formed by the other two radiation branches, so as to realize the distinction between the left-handed circular polarization and the right-handed circular polarization.

[0096] In addition, the first connection point and the second connection point can respectively reduce the coupling effect between the radiation branches connected perpendicularly to each other, so that the radiation branches can better radiate independently, and then superimpose circularly polarized waves in space.

Since the second radiation branch 2 and the first radiation branch 1 are perpendicular to each other in structure and have the same length, the first condition of the circular polarization radiation, i.e., the electric field with the same amplitude and the perpendicular direction, is met. Through the first feed source 7, the electric field with the perpendicular direction and the phase difference of 90 degrees can be generated, so that the left-handed circular polarization electromagnetic wave can be excited. The right-handed circular polarization required for the Beidou receiving antenna is implemented in the same way.
