[0023] See also Figure 1 , is a simple structural diagram of the antenna assembly 1 in some embodiments of the present application. Figure 1 As shown, the antenna assembly 1 includes a first radiation branch 11, a second radiation branch 12 and a feeding excitation branch 13. The first radiation branch 11 and the second radiation branch 12 are arranged at an angle. The feeding excitation branch 13 is located between the first radiating branch 11 and the second radiating branch 12 and is spaced apart from the first radiating branch 11 and the second radiating branch 12. The feeding excitation branch 13 includes a feeding point K1 for accessing a feeding signal. An electrical coupling is formed between the feeding excitation branch 13 and the first radiating branch 11, and the feeding signal is coupled to the first radiating branch 11 to form a first coupled feeding signal fed into the first radiating branch 11. A magnetic coupling is formed between the feeding excitation branch 13 and the second radiating branch 12, and the feeding signal is coupled to the second radiating branch 12 to form a second coupled feeding signal fed into the second radiating branch 12. A phase difference between the first coupled feeding signal and the second coupled feeding signal is 90°, so that the first radiating branch 11 and the second radiating branch 12 have circularly polarized radiation characteristics or elliptically polarized radiation characteristics, so that the antenna assembly 1 supports the reception and / or transmission of satellite communication signals.

[0024] Therefore, in the present application, the feed excitation branch 13 is coupled with the first radiation branch 11 and the second radiation branch 12 through electrical coupling and magnetic coupling respectively, so that the phase difference between the two coupled feed signals obtained after the feed signal received by the feed excitation branch 13 is electrical coupling and magnetic coupling is 90°, and because the first radiation branch 11 and the second radiation branch 12 are arranged at an angle, the first radiation branch 11 and the second radiation branch 12 have circularly polarized radiation characteristics or elliptically polarized radiation characteristics, so that the reception and / or transmission of satellite communication signals can be achieved through a simple and compact structure.

[0025] Among them, in this application, the feeding excitation branch 13 serves as a feeding excitation structure, which is used to couple the received feeding signal to the first radiation branch 11 and the second radiation branch 12 through electrical coupling and magnetic coupling, respectively, to play the role of feeding signal conduction and excitation, and itself may not participate in radiation.

[0026] In some embodiments, the feeding excitation branch 13 further includes a first end D1, a second end D2 and a first grounding point G1 for grounding, the first grounding point G1 is set at the second end D2, the first end D1 is an open-circuit end, and the feeding point K1 is set between the first grounding point G1 and the first end D1; the first radiation branch 11 includes a third end D3, a fourth end D4 and a second grounding point G2 for grounding, the second grounding point G2 is set at the fourth end D4, and the third end D3 is an open-circuit end; the second radiation branch 12 includes a fifth end D5, a sixth end D6 and a third grounding point G3 for grounding, the third grounding point G3 is set at the fifth end D5, and the sixth end D6 is an open end; the first end D1 of the feeding excitation branch 13 is opposite to the third end D3 of the first radiation branch 11 and is spaced apart, the second end D2 of the feeding excitation branch 13 is opposite to the fifth end D5 of the second radiation branch 12 and is spaced apart, or the second end D2 of the feeding excitation branch 13 is connected to the fifth end D5 of the second radiation branch 12 and the first grounding point G1 coincides with the third grounding point G3.

[0027] Thus, the first end D1 of the feeding excitation branch 13 is an open-circuit end, the second end D2 is a grounded end grounded through the first grounding point G1, the third end D3 of the first radiating branch 11 is also an open-circuit end, the fourth end D4 is a grounded end grounded through the second grounding point G2, the fifth end D5 of the second radiating branch 12 is a grounded end grounded through the third grounding point G3, and the sixth end D6 is also an open-circuit end. The electric field at the open-circuit first end D1 of the feeding excitation branch 13 is the largest. By aligning the open-circuit first end D1 of the feeding excitation branch 13 with the open-circuit third end D3 of the first radiating branch 11 and spacing them apart, the strongest electric field coupling can be generated, thereby forming an electrical coupling between the feeding excitation branch 13 and the first radiating branch 11. In addition, the current at the second end D2 of the feeding excitation branch 13, which serves as the grounding end, is the largest, and the magnetic field strength is proportional to the current. Therefore, the magnetic field strength at the second end D2 of the feeding excitation branch 13, which serves as the grounding end, is the largest. The second end D2 of the feeding excitation branch 13, which serves as the grounding end, and the fifth end D5 of the second radiation branch 12, which serves as the grounding end, are placed opposite and spaced apart, or the second end D2 of the feeding excitation branch 13 is connected to the fifth end D5 of the second radiation branch 12 and the first grounding point G1 coincides with the third grounding point G3. This can generate the strongest magnetic field coupling, thereby forming magnetic coupling between the feeding excitation branch 13 and the second radiation branch 12.

[0028] The electric coupling in this application refers to electric field coupling, and the magnetic coupling refers to magnetic field coupling. Due to the characteristics of electromagnetic wave signals, the electric field and the magnetic field are perpendicular, which results in a 90° phase difference between the two coupled feed signals obtained after the feed signal received by the feed excitation branch 13 undergoes electric coupling and magnetic coupling.

[0029] like Figure 1 As shown, the second end D2 of the feeding excitation branch 13 serving as the ground end and the fifth end D5 of the second radiation branch 12 serving as the ground end are opposite to each other and spaced apart.

[0030] See also Figure 2 , is another simple structural diagram of the antenna assembly 1 in some embodiments of the present application. Figure 2 As shown, Figure 1 The difference is that the second end D2 of the feeding excitation branch 13 serving as the ground end is directly connected to the fifth end D5 of the second radiation branch 12 serving as the ground end, and the first grounding point G1 coincides with the third grounding point G3.

[0031] exist Figure 2In the manner shown, since the sixth end D6 of the second radiation branch 12 is an open-circuit end, the current at the second end D2 of the feeding excitation branch 13 serving as the ground end and the fifth end D5 of the second radiation branch 12 serving as the ground end is the largest, and magnetic coupling is also formed between the feeding excitation branch 13 and the second radiation branch 12, and the second feeding coupling signal is excited to be generated in the second radiation branch 12, so that the second feeding coupling signal is fed into the second radiation branch 12.

[0032] Therefore, in some embodiments, the second end D2 of the feeding excitation branch 13 serving as the ground end can be directly connected to the fifth end D5 of the second radiation branch 12 serving as the ground end, which can also achieve magnetic coupling, reduce gaps, and improve the stability of the overall structure of the antenna assembly 1.

[0033] The second grounding point G2 is set at the fourth end D4, which does not mean that the second grounding point G2 needs to be strictly set at the fourth end D4, and may also include the case where the second grounding point G2 is set at a position close to the fourth end D4. When the second end D2 of the feeding excitation branch 13, which serves as the grounding end, and the fifth end D5 of the second radiation branch 12, which serves as the grounding end, are directly opposite and spaced apart, the first grounding point G1 is set at the second end D2, which does not need to be strictly set at the second end D2, and may also include the case where the first grounding point G1 is set at a position close to the second end D2. The third grounding point G3 is set at the fifth end D5, which does not need to be strictly set at the fifth end D5, and may also include the case where the third grounding point G3 is set at a position close to the fifth end D5.

[0034] In some embodiments, the first radiation branch 11 and the second radiation branch 12 form an angle, which means that the angle between the first radiation branch 11 and the second radiation branch 12 is greater than 0° and less than 180°.

[0035] In some embodiments, when the angle between the first radiating branch 11 and the second radiating branch 12 is 90°, the vertical polarization requirement of the circularly polarized antenna is met. At this time, the first radiating branch 11 and the second radiating branch 12 can have relatively strict circularly polarized radiation characteristics.

[0036] In some embodiments, when the first radiating branch 11 and the second radiating branch 12 are at an angle other than 90°, the first radiating branch 11 and the second radiating branch 12 are not completely vertically polarized, but have elliptically polarized radiation characteristics. At this time, the antenna radiation performance will be lower than the antenna radiation performance under circularly polarized radiation characteristics, but it can also meet the requirements of satellite communication.

[0037] In some embodiments, in order to improve the circular polarization or elliptical polarization radiation performance of the first radiation branch 11 and the second radiation branch 12 , the angle between the first radiation branch 11 and the second radiation branch 12 may be greater than 10° and less than 170°.

[0038] In some embodiments, as Figure 1 As shown, the angle between the first radiating branch 11 and the second radiating branch 12 is 90°, so that the first radiating branch 11 and the second radiating branch 12 are vertically orthogonal. When the phase difference between the two coupled feed signals fed into the first radiating branch 11 and the second radiating branch 12 is 90°, vertical orthogonal polarization in a strict sense can be achieved. As mentioned above, the circular polarization radiation performance can be more strictly achieved, and the maximum radiation performance of satellite communication can be achieved.

[0039] Obviously, when the angle between the first radiating branch 11 and the second radiating branch 12 is not 90°, that is, it is other values ​​greater than 0° and less than 180°, the circular polarization radiation performance will be weakened, and an elliptical polarization radiation characteristic will be formed, but it can still meet the needs of satellite communication and support satellite communication.

[0040] Please also refer to Figure 3 , is a schematic diagram of the current distribution of the antenna assembly 1 under electric coupling and magnetic coupling in an embodiment of the present application. Figure 3 The current distribution diagram obtained by simulation is as follows: the angle between the first radiation branch 11 and the second radiation branch 12 is 90°. For example, Figure 1 Schematic diagram of current distribution obtained by simulating the structure shown.

[0041] As mentioned above, the first end D1 of the feeding excitation branch 13 as an open end and the third end D3 of the first radiation branch 11 as an open end are opposite and spaced apart, generating the strongest electric field coupling. Figure 3 As shown, under the action of the magnetic field coupling, a current i1 is generated in the first radiation branch 11 and flows along the length direction of the first radiation branch 11. Since the feeding signal itself is a high-frequency current signal, in fact, the current i1 generated in the first radiation branch 11 can be regarded as the first coupled feeding signal fed into the first radiation branch 11.

[0042] As mentioned above, when the second end D2 of the feeding excitation branch 13 as the ground end is directly opposite to and spaced from the fifth end D5 of the second radiation branch 12 as the ground end, or when the second end D2 of the feeding excitation branch 13 is connected to the fifth end D5 of the second radiation branch 12 and the first grounding point G1 coincides with the third grounding point G3, the strongest magnetic field coupling can be generated. Figure 3 As shown, under the action of the magnetic field coupling, a current i2 is generated in the second radiation branch 12 and flows along the length direction of the second radiation branch 12. Since the feeding signal itself is a high-frequency current signal, in fact, the current i2 generated in the second radiation branch 12 can be regarded as a second coupled feeding signal fed into the second radiation branch 12.

[0043] Therefore, from Figure 3 It can be seen that the direction of the current i1 in the first radiation branch 11 is perpendicular to the direction of the current i2 in the second radiation branch 12. As mentioned above, through electrical coupling and magnetic coupling, the two coupled feeding signals fed into the first radiation branch 11 and the second radiation branch 12, that is, when the phase difference of the current is 90°, vertical orthogonal polarization can be achieved, and the strictly circular polarization radiation characteristics can be achieved, thereby achieving the best radiation performance.

[0044] In some embodiments, the feed signal received by the feed point K1 may be a feed signal provided by a feed source or a received satellite communication signal. Specifically, when the antenna assembly 1 is used to transmit a satellite communication signal, the feed signal received by the feed point K1 may be a feed signal provided by a feed source; when the antenna assembly 1 is used to receive a satellite communication signal, the feed signal fed into the feed point K1 may be a received satellite communication signal.

[0045] Please also refer to Figure 4 , is a further structural diagram of the antenna assembly 1 in some embodiments of the present application. Figure 4 As shown, the antenna assembly 1 also includes a feed source S1, which is used to generate the feed signal. The feed signal generated by the feed source S1 is coupled to the first radiating branch 11 through the feed excitation branch 13 to form a first coupled feed signal fed into the first radiating branch 11. The feed signal generated by the feed source S2 is also coupled to the second radiating branch 12 through the feed excitation branch 13 to form a second coupled feed signal fed into the second radiating branch 12. The phase difference between the first coupled feed signal and the second coupled feed signal is 90°, so that the first radiating branch 11 and the second radiating branch 12 respectively realize the transmission of satellite communication signals under the excitation of the first coupled feed signal and the second coupled feed signal.

[0046] That is, in some embodiments, the antenna assembly 1 supports the transmission of satellite communication signals. After receiving the feed signal from the feed source S1, the feed excitation branch 13 is coupled to the first radiating branch 11 through the feed excitation branch 13 to form a first coupled feed signal fed into the first radiating branch 11. The feed signal generated by the feed source S2 is also coupled to the second radiating branch 12 through the feed excitation branch 13 to form a second coupled feed signal fed into the second radiating branch 12. The phase difference between the first coupled feed signal and the second coupled feed signal is 90°, so that the first radiating branch 11 and the second radiating branch 12 respectively realize the transmission of satellite communication signals under the excitation of the first coupled feed signal and the second coupled feed signal.

[0047] In some embodiments, the electrical length of the first radiation branch 11 and the second radiation branch 12 is λ1 / 4, where λ1 is the wavelength corresponding to the transmission frequency of the satellite communication signal, and λ1 / 4 refers to one quarter of λ1.

[0048] When the electrical length of the first radiation branch 11 and the second radiation branch 12 is λ1 / 4, the first radiation branch 11 and the second radiation branch 12 resonate at the transmission frequency of the satellite communication signal to achieve better or optimal radiation performance.

[0049] In some embodiments, the length of the feed excitation branch 13 is also λ1 / 4. When the electrical length of the feed excitation branch 13 is λ1 / 4, when the feed excitation branch 13 receives the feed signal received by the feed source S1, the electric field coupling strength generated by the first end D1 as an open-circuit end and the third end D3 as an open-circuit end of the first radiation branch 11 facing and spaced apart is the maximum value that can be achieved. The intensity of the magnetic field coupling generated by the second end D2 as a grounded end of the feed excitation branch 13 is also the maximum value that can be achieved. For a feed excitation branch 13 of any length, the strongest point of the electric field coupling strength is at the first end D1 as an open-circuit end, and the strongest point of the magnetic field coupling strength is at the second end D2 as a short-circuit end. However, when the electrical length of the feeding excitation branch 13 is λ1 / 4, which is the wavelength corresponding to the transmission frequency of the satellite communication signal, when the satellite communication signal is transmitted, the electric field coupling strength of the first end D1 as the open end will be stronger than the electric field coupling strength of the feeding excitation branch 13 with other electrical lengths, and the magnetic field coupling strength at the second end D2 as the short-circuit end will also be stronger than the magnetic field coupling strength of the feeding excitation branch 13 with other electrical lengths. Thus, the electric field coupling strength and the magnetic field coupling strength can reach the maximum value that can be achieved.

[0050] That is, in some embodiments, the electrical lengths of the feeding excitation branch 13, the first radiation branch 11, and the second radiation branch 12 are mainly designed based on achieving the transmission of the satellite communication signal.

[0051] In some embodiments, the feeding excitation branch 13, the first radiating branch 11, and the second radiating branch 12 are all in the shape of elongated strips, and the electrical lengths of the feeding excitation branch 13, the first radiating branch 11, and the second radiating branch 12 may be substantially equal to the lengths of the feeding excitation branch 13, the first radiating branch 11, and the second radiating branch 12. The first end D1 and the second end D2 of the feeding excitation branch 13 are two ends in the extension direction of the feeding excitation branch 13, and the length of the feeding excitation branch 13 is substantially the length from the first end D1 to the second end D2 along the extension direction of the feeding excitation branch 13. The third end D3 and the fourth end D4 of the first radiating branch 11 are two ends in the extension direction of the first radiating branch 11, and the length of the first radiating branch 11 is substantially the length from the third end D3 to the fourth end D4 along the extension direction of the first radiating branch 11. Similarly, the fifth end D5 and the sixth end D6 of the second radiating branch 12 are the two ends in the extension direction of the second radiating branch 12, and the length of the second radiating branch 12 is roughly the length from the fifth end D5 to the sixth end D6 along the extension direction of the second radiating branch 12.

[0052] The extending direction of the feeding excitation branch 13 , the first radiation branch 11 and the second radiation branch 12 refers to the extending direction of the long sides of the feeding excitation branch 13 , the first radiation branch 11 and the second radiation branch 12 .

[0053] Among them, such as Figures 1-4 As shown, the feeding excitation branch 13 is an arc-shaped long strip, and the first radiation branch 11 and the second radiation branch 12 can be a straight long strip.

[0054] Please also refer to Figure 5, is a further structural diagram of the antenna assembly 1 in some embodiments of the present application. The antenna assembly 1 also includes a first tuning unit 14, a second tuning unit 15, and a third tuning unit 16. The first tuning unit 14 is connected between the first grounding point G1 and the ground, the second tuning unit 15 is connected between the second grounding point G2 and the ground, and the third tuning unit 16 is connected between the third grounding point G3 and the ground. That is, in some embodiments, the first grounding point G1 is grounded through the first tuning unit 14, the second grounding point G2 is grounded through the second tuning unit 15, and the third grounding point G3 is grounded through the third tuning unit 16. The first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 are used to enable reception of satellite communication signals, and adjust the electrical lengths of the feed excitation branch 13, the first radiation branch 11, and the second radiation branch 12 to λ2 / 4 to achieve reception of satellite communication signals, wherein λ2 is the wavelength corresponding to the reception frequency of the satellite communication signal. Here, the λ2 / 4 refers to one quarter of λ2.

[0055] That is, in some embodiments, in certain satellite communication systems, the receiving frequency and the transmitting frequency of the satellite communication signal are different, and by configuring the first tuning unit 14, the second tuning unit 15 and the third tuning unit 16 to adjust the electrical length, the antenna assembly 1 can further realize the reception of the satellite communication signal.

[0056] Thus, in some embodiments, the antenna assembly 1 can not only receive satellite communication signals, but also transmit satellite communication signals. That is, the antenna assembly 1 can support both the transmission and reception of satellite communication signals in a time-sharing manner.

[0057] Obviously, in some embodiments, when the receiving frequency and the transmitting frequency of the satellite communication signal are the same, the first tuning unit 14, the second tuning unit 15 and the third tuning unit 16 can be omitted, and the first grounding point G1, the second grounding point G2 and the third grounding point G3 are directly grounded.

[0058] See also Figure 6, is a schematic diagram of the internal structure of the tuning unit in some embodiments of the present application. The first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 each include a tuning element X1 and a tuning switch W1 connected in parallel between the corresponding grounding point and the ground. The tuning switches W1 of the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 are disconnected when receiving satellite communication signals, thereby enabling the corresponding tuning element X1. That is, the branch where the corresponding tuning element X1 is located is not short-circuited by the tuning switch W1 and can be connected between the corresponding grounding point and the ground, thereby enabling the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 to receive satellite communication signals.

[0059] That is, in some embodiments, enabling the first tuning unit 14 , the second tuning unit 15 , and the third tuning unit 16 means that tuning elements in the first tuning unit 14 , the second tuning unit 15 , and the third tuning unit 16 are enabled.

[0060] In some embodiments, the tuning switch W1 is turned on when transmitting satellite communication signals, short-circuiting the branch where the corresponding tuning element X1 is located, thereby disabling the branch where the corresponding tuning element X1 is located. The first grounding point G1, the second grounding point G2, and the third grounding point G3 are directly grounded through the turned-on tuning switch W1. As a result, the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 are disabled when transmitting satellite communication signals.

[0061] in, Figure 6 The first tuning unit 14 is used as an example for explanation. Figure 6 As shown, the first tuning unit 14 includes a tuning element X1 and a tuning switch W1 connected in parallel between the first ground point G1 and the ground. Similarly, the second tuning unit 15 includes a tuning element X1 and a tuning switch W1 connected in parallel between the second ground point G2 and the ground, and the third tuning unit 16 also includes a tuning element X1 and a tuning switch W1 connected in parallel between the third ground point G3 and the ground.

[0062] Wherein, each tuning element X1 may include a capacitor and / or an inductor, and when both a capacitor and an inductor are included, the capacitor and the inductor may be connected in parallel or in series. Wherein, the capacitance and / or inductance of the tuning element X1 included in the first tuning unit 14 may be equivalent to an electrical length, and the sum of the equivalent electrical length of the tuning element X1 included in the first tuning unit 14 and the original electrical length of the feeding excitation branch 13 is λ2 / 4. Similarly, the capacitance and / or inductance of the tuning element X1 included in the second tuning unit 15 may be equivalent to an electrical length, and the sum of the equivalent electrical length of the tuning element X1 included in the second tuning unit 15 and the original electrical length of the first radiation branch 11 is λ2 / 4. The capacitance and / or inductance of the tuning element X1 included in the third tuning unit 16 may be equivalent to an electrical length, and the sum of the equivalent electrical length of the tuning element X1 included in the third tuning unit 16 and the original electrical length of the second radiation branch 12 is λ2 / 4.

[0063] Thus, the inductance and / or capacitance value of the tuning element X1 included in the first tuning unit 14 can be preset to meet the requirement that the sum of the equivalent electrical length of the tuning element X1 and the original electrical length of the feed excitation branch 13 is λ2 / 4, the inductance and / or capacitance value of the tuning element X1 included in the second tuning unit 15 can be preset to meet the requirement that the sum of the equivalent electrical length of the tuning element X1 and the original electrical length of the first radiation branch 11 is λ2 / 4, and the inductance and / or capacitance value of the tuning element X1 included in the third tuning unit 16 can be preset to meet the requirement that the sum of the equivalent electrical length of the tuning element X1 and the original electrical length of the second radiation branch 12 is λ2 / 4.

[0064] Among them, when the electrical length of the feeding excitation branch 13 is adjusted to λ2 / 4, when the feeding excitation branch 13 receives the satellite communication signal, the electric field coupling intensity generated by the first end D1 as the open end and the third end D3 as the open end of the first radiation branch 11 facing each other and being spaced apart can reach the maximum value that can be achieved, and the magnetic field coupling intensity generated by the second end D2 as the ground end of the feeding excitation branch 13 can also reach the maximum value that can be achieved.

[0065] When the electrical lengths of the first radiation branch 11 and the second radiation branch 12 are adjusted to λ2 / 4, the first radiation branch 11 and the second radiation branch 12 resonate at the receiving frequency of the satellite communication signal, thereby achieving better or optimal radiation performance.

[0066] Among them, the first tuning unit 14 is connected to the feeding excitation branch 13 after being enabled, and can be regarded as a part of the feeding excitation branch 13. The electrical length of the feeding excitation branch 13, the first radiation branch 11 and the second radiation branch 12 is adjusted to λ2 / 4, which respectively means that the sum of the equivalent electrical length of the tuning element X1 and the original electrical length of the feeding excitation branch 13 is λ2 / 4, the sum of the equivalent electrical length of the tuning element X1 and the original electrical length of the first radiation branch 11 is λ2 / 4, and the sum of the equivalent electrical length of the tuning element X1 and the original electrical length of the second radiation branch 12 is λ2 / 4.

[0067] In other embodiments, Figure 1 In the structure shown, the feed signal received by the aforementioned feeding point K1 is a received satellite communication signal. The feed signal is coupled to the first radiating branch to form a first coupled feed signal fed into the first radiating branch. The feed signal is coupled to the second radiating branch to form a second coupled feed signal fed into the second radiating branch. The phase difference between the first coupled feed signal and the second coupled feed signal is 90°, so that the first radiating branch and the second radiating branch respectively receive the satellite communication signal under the excitation of the first coupled feed signal and the second coupled feed signal.

[0068] That is, in other embodiments, Figure 1 The structure shown may also be a structure that supports the reception of satellite communication signals.

[0069] In some other embodiments, the electrical length of the first radiation branch 11 and the second radiation branch 12 is λ2 / 4, where λ2 is the wavelength corresponding to the receiving frequency of the satellite communication signal. In some other embodiments, the electrical length of the feeding excitation branch 13 is also λ2 / 4.

[0070] That is, in other embodiments, the electrical lengths of the feeding excitation branch 13, the first radiating branch 11, and the second radiating branch 12 are primarily designed based on achieving reception of the satellite communication signal. For related explanations, refer to the aforementioned section regarding the electrical lengths of the feeding excitation branch 13, the first radiating branch 11, and the second radiating branch 12 being primarily designed based on achieving transmission of the satellite communication signal.

[0071] In other embodiments, Figure 5In the illustrated structure, the antenna assembly 1 further includes a first tuning unit 14, a second tuning unit 15, and a third tuning unit 16. The first tuning unit 14 is connected between the first ground point G1 and ground, the second tuning unit 15 is connected between the second ground point G2 and ground, and the third tuning unit 16 is connected between the third ground point G3 and ground. That is, in some embodiments, the first ground point G1 is grounded via the first tuning unit 14, the second ground point G2 is grounded via the second tuning unit 15, and the third ground point G3 is grounded via the third tuning unit 16. The first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 are configured to enable transmission of satellite communication signals, and adjust the electrical lengths of the feed excitation branch 13, the first radiating branch 11, and the second radiating branch 12 to λ1 / 4 to achieve transmission of satellite communication signals, where λ1 is the wavelength corresponding to the transmission frequency of the satellite communication signal.

[0072] That is, in other embodiments, the electrical lengths of the feeding excitation branch 13, the first radiation branch 11 and the second radiation branch 12 are mainly designed based on the realization of the reception of the satellite communication signal, and by configuring the first tuning unit 14, the second tuning unit 15 and the third tuning unit 16 to be enabled when the satellite communication signal is transmitted, the electrical lengths of the feeding excitation branch 13, the first radiation branch 11 and the second radiation branch 12 can be adjusted to λ1 / 4 when the satellite communication signal is transmitted to realize the transmission of the satellite communication signal.

[0073] Similarly, as mentioned above Figure 6 As shown, the first tuning unit 14, the second tuning unit 15 and the third tuning unit 16 all include a tuning element X1 and a tuning switch W1 connected in parallel between the corresponding grounding point and the ground. The tuning switches W1 of the first tuning unit 14, the second tuning unit 15 and the third tuning unit 16 are disconnected when transmitting satellite communication signals, and the corresponding tuning element X1 is enabled, that is, the branch where the corresponding tuning element X1 is located will not be short-circuited by the tuning switch W1, but can be connected between the corresponding grounding point and the ground, so that the first tuning unit 14, the second tuning unit 15 and the third tuning unit 16 are enabled when transmitting satellite communication signals.

[0074] In other embodiments, the tuning switch W1 is turned on when receiving satellite communication signals, short-circuiting the branch where the corresponding tuning element X1 is located, thereby disabling the branch where the corresponding tuning element X1 is located. The first grounding point G1, the second grounding point G2, and the third grounding point G3 are directly grounded through the turned-on tuning switch W1. As a result, the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 are disabled when receiving satellite communication signals.

[0075] Wherein, each tuning element X1 may include a capacitor and / or an inductor, and when both a capacitor and an inductor are included, the capacitor and the inductor may be connected in parallel or in series. Wherein, the capacitance and / or inductance of the tuning element X1 included in the first tuning unit 14 may be equivalent to an electrical length, and the sum of the equivalent electrical length of the tuning element X1 included in the first tuning unit 14 and the original electrical length of the feeding excitation branch 13 is λ1 / 4. Similarly, the capacitance and / or inductance of the tuning element X1 included in the second tuning unit 15 may be equivalent to an electrical length, and the sum of the equivalent electrical length of the tuning element X1 included in the second tuning unit 15 and the original electrical length of the first radiation branch 11 is λ1 / 4. The capacitance and / or inductance of the tuning element X1 included in the third tuning unit 16 may be equivalent to an electrical length, and the sum of the equivalent electrical length of the tuning element X1 included in the third tuning unit 16 and the original electrical length of the second radiation branch 12 is λ1 / 4.

[0076] Thus, in other embodiments, the inductance and / or capacitance value of the tuning element X1 included in the first tuning unit 14 can be preset to satisfy that the sum of the equivalent electrical length of the tuning element X1 and the original electrical length of the feed excitation branch 13 is λ1 / 4, the inductance and / or capacitance value of the tuning element X1 included in the second tuning unit 15 can be preset to satisfy that the sum of the equivalent electrical length of the tuning element X1 and the original electrical length of the first radiating branch 11 is λ1 / 4, and the inductance and / or capacitance value of the tuning element X1 included in the third tuning unit 16 can be preset to satisfy that the sum of the equivalent electrical length of the tuning element X1 and the original electrical length of the second radiating branch 12 is λ1 / 4. Thus, in other embodiments, the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 are used to be enabled when transmitting a satellite communication signal, so that the antenna assembly 1 can resonate at the transmission frequency of the satellite communication signal.

[0077] Thus, in other embodiments, when the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 are not enabled, i.e., disabled, the antenna assembly 1 can support the reception of satellite communication signals. When it is necessary to transmit satellite communication signals, the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 can be enabled, so that the antenna assembly 1 can support the transmission of satellite communication signals. Thus, similarly through a time-sharing approach, both the transmission and reception of satellite communication signals are supported.

[0078] As mentioned above, when transmitting the satellite communication signal, the feed signal is the feed signal provided by the feed source S1.

[0079] See also Figure 7 , is a structural block diagram of the electronic device 100 in some embodiments of the present application. Figure 7 As shown, the electronic device 100 may include the antenna assembly 1 in any of the aforementioned embodiments.

[0080] Thus, the electronic device 100 can transmit and / or receive satellite communication signals by being equipped with the antenna assembly 1 having a simple and compact structure as described above, which can make the overall volume of the electronic device 100 smaller and easier to carry.

[0081] See also Figure 8 , is a schematic plan view of the electronic device 100 in some embodiments of the present application. Figure 8 As shown, the electronic device 100 further includes a frame 10 , wherein the first radiation branch 11 , the second radiation branch 12 and the feeding excitation branch 13 are metal segments provided on the frame 10 of the electronic device 100 .

[0082] like Figure 8 As shown, in some embodiments, the frame 10 of the electronic device 100 is a metal frame, and the first radiation branch 11, the second radiation branch 12, and the feeding and excitation branch 13 are metal frame segments 101 formed by opening a gap F1 in the metal frame of the electronic device 100. The first radiation branch 11 is formed by the metal frame on the first side B1 of the electronic device 100, the second radiation branch 12 is formed by the metal frame on the second side B2 of the electronic device 100, the first side B1 and the second side B2 are adjacent sides, and the feeding and excitation branch 13 is the metal frame segment at the vertex between the first side B1 and the second side B2.

[0083] Among them, when the first end D1 of the feeding excitation branch 13 is opposite to and spaced apart from the third end D3 of the first radiation branch 11, and the second end D2 of the feeding excitation branch 13 is opposite to and spaced apart from the fifth end D5 of the second radiation branch 12, the first radiation branch 11, the second radiation branch 12 and the feeding excitation branch 13 are three independent metal frame segments 101 formed by opening a gap F1 in the metal frame of the electronic device 100. When the first end D1 of the feeding excitation branch 13 is opposite to the third end D3 of the first radiation branch 11 and is spaced apart, the second end D2 of the feeding excitation branch 13 is connected to the fifth end D5 of the second radiation branch 12 and the first grounding point G1 coincides with the third grounding point G3, the second radiation branch 12 and the feeding excitation branch 13 are an integral metal frame segment 101, and the first radiation branch 11 is an independent metal frame segment 101, and there is a gap F1 between the metal frame segment 101 forming the second radiation branch 12 and the feeding excitation branch 13.

[0084] Among them, the first end D1 of the feeding excitation branch 13 is opposite to the third end D3 of the first radiating branch 11 and is arranged at intervals, the second end D2 of the feeding excitation branch 13 is connected to the fifth end D5 of the second radiating branch 12, and the first grounding point G1 coincides with the third grounding point G3. In this structure, electrical coupling and magnetic coupling can also be achieved, and the gaps can be reduced, and the stability of the overall structure of the antenna assembly 1 is improved. For the electronic device 100, it can also improve the overall strength of the frame and reduce the complexity of the process.

[0085] In some embodiments, the frame 10 of the electronic device 100 may also be a non-metal frame, and the first radiation branch 11 , the second radiation branch 12 and the feeding excitation branch 13 are metal segments arranged in the frame 10 of the electronic device 100 .

[0086] That is, in some embodiments, the frame 10 of the electronic device 100 may also be made of non-metallic materials with low electrical conductivity, such as plastic, ceramic, etc. The first radiation branch 11, the second radiation branch 12, and the feed excitation branch 13 are metal segments disposed in the frame 10 of the electronic device 100.

[0087] Among them, the first radiation branch 11 is a metal segment set in the frame 10 of the first side B1 of the electronic device 100, the second radiation branch 12 is a metal segment set in the frame 10 of the second side B2 of the electronic device 100, the first side B1 and the second side B2 are adjacent sides, and the feeding excitation branch 13 is a metal segment in the frame 10 placed at the top corner between the first side B1 and the second side B2 of the electronic device 100.

[0088] In which, similarly, when the first end D1 of the feeding excitation branch 13 is opposite to and spaced apart from the third end D3 of the first radiation branch 11, and the second end D2 of the feeding excitation branch 13 is opposite to and spaced apart from the fifth end D5 of the second radiation branch 12, the first radiation branch 11, the second radiation branch 12 and the feeding excitation branch 13 are three independent metal segments arranged in the frame 10 of the electronic device 100. When the first end D1 of the feeding excitation branch 13 is opposite to the third end D3 of the first radiation branch 11 and is spaced apart, the second end D2 of the feeding excitation branch 13 is connected to the fifth end D5 of the second radiation branch 12 and the first grounding point G1 coincides with the third grounding point G3, the second radiation branch 12 and the feeding excitation branch 13 are an integral metal segment arranged on the frame 10 of the electronic device 100, and the first radiation branch 11 is another independent metal segment arranged on the frame 10 of the electronic device 100, and there is a gap between the first radiation branch 11 and the metal segment forming the second radiation branch 12 and the feeding excitation branch 13.

[0089] Among them, when the frame 10 of the electronic device 100 can also be a non-metal frame, the first radiation branch 11, the second radiation branch 12 and the feeding excitation branch 13 can be embedded in the frame 10 of the electronic device 100, or arranged on the inner side of the frame 10 of the electronic device 100.

[0090] In some embodiments, as Figure 8 As shown, the first side B1 is the short side of the electronic device 100, and the second side B2 is the long side of the electronic device 100. Therefore, since the adjacent first sides B1 and second sides B2 are perpendicular, the first radiation branches 11 and the second radiation branches 12 are also arranged relatively perpendicularly, thereby achieving vertical orthogonality and achieving better vertical orthogonal polarization.

[0091] Obviously, in other embodiments, the first side B1 may be the long side of the electronic device 100 , and the second side B2 may be the short side of the electronic device 100 .

[0092] Among them, such as Figure 8 As shown, the frame 10 is arc-shaped at the vertex between the first side B1 and the second side B2, and the feeding excitation branch 13 is an arc segment.

[0093] like Figure 8 As shown, in some embodiments, the first side B1 is a short side at the top of the electronic device 100 , and the second side B2 is a long side located on the left side of the electronic device 100 .

[0094] Among them, the directional terms such as "top" and "bottom" used in the embodiments of the present application to describe the electronic device 100 are mainly explained based on the orientation of the electronic device 100 when the user holds it in hand. The position toward the top side of the electronic device 100 is referred to as the "top", and the position toward the bottom side of the electronic device 100 is referred to as the "bottom". It does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the orientation of the electronic device 100 in actual application scenarios. In some embodiments, the bottom end of the electronic device 100 is the end where the headphone jack and the USB port are provided, and the top of the electronic device 100 is the other end opposite to the end where the headphone jack and the USB port are provided, and may also refer to the end where a camera, a receiver, etc. are provided.

[0095] Among them, such as Figure 8 As shown, the electronic device 100 further includes a display screen 2. Figure 9 The schematic diagram shown is a schematic diagram viewed from one side of the display screen 2. The "left" and "right" are Figure 9 "Left" and "right" from the perspective of .

[0096] Obviously, in some embodiments, the first side B1 is also the short side of the top of the electronic device 100 , the second side B2 is the long side located on the right side of the electronic device 100 , and so on.

[0097] See also Figure 9 , is a partial structural diagram of the electronic device 100 in some embodiments of the present application including the aforementioned antenna assembly 1. Figure 9 As shown, the electronic device 100 further includes a circuit board 3, the feed source S1 can be arranged on the circuit board 3, and the feed point K1 is connected to the feed source S1, as shown in FIG. Figure 9 As shown, the first grounding point G1, the second grounding point G2 and the third grounding point G3 are connected to the ground on the circuit board 3. Specifically, Figure 9 The electronic device 100 includes Figure 4 The antenna assembly 1 shown in FIG is used as an example for illustration.

[0098] The circuit board 3 may be a mainboard, and the ground on the circuit board 3 may be a mainboard ground, for example, a ground region or a ground layer on the circuit board 3. In some embodiments, the middle frame of the electronic device 100 serves as the entire device ground. The mainboard ground may be connected to the middle frame (not shown) of the electronic device 100, thereby connecting the first ground point G1, the second ground point G2, and the third ground point G3 to the middle frame of the electronic device 100 to achieve connection to the entire device ground. The aforementioned ground may be the ground on the circuit board 20 or the middle frame ground.

[0099] in, Figure 9The structure of the antenna assembly 1 shown in the figure specifically does not include the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16. Obviously, when the antenna assembly 1 includes the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16, the first grounding point G1 is connected to the ground on the circuit board 3 through the first tuning unit 14, the second grounding point G2 is connected to the ground on the circuit board 3 through the second tuning unit 15, and the third grounding point G3 is connected to the ground on the circuit board 3 through the third tuning unit 16.

[0100] In some embodiments, the first radiation branch 11, the second radiation branch 12, and the feeding and excitation branch 13 may also be metal segments disposed on the circuit board 3. For example, the first radiation branch 11, the second radiation branch 12, and the feeding and excitation branch 13 are FPC (flexible printed circuit) metal segments fixedly disposed on the antenna bracket, or LDS (Laser-Direct-Structuring) metal segments formed on the antenna bracket using laser technology, and then disposed on the circuit board 3 through the antenna bracket.

[0101] See also Figure 10 , is a first three-dimensional axial ratio simulation diagram of the electronic device 100 in some embodiments of the present application. Figure 11 The first three-dimensional axial ratio simulation diagram of the electronic device 100 shown is a three-dimensional axial ratio simulation diagram of side radiation obtained by simulating the structure of the antenna assembly 1 shown in any of the aforementioned embodiments included in the electronic device 100.

[0102] like Figure 10 It can be seen that, viewed from the side of the electronic device 100, the radiation intensity radiated to the side by the antenna assembly 1 is roughly equal within a circle centered on the top, so that the ratio of the maximum radiation intensity to the minimum radiation intensity is roughly 1, achieving a low axial ratio in the side direction of the electronic device 100.

[0103] Among them, the lower the axial ratio, the better the circular polarization characteristics, and generally the lowest axial ratio is 1.

[0104] in, Figure 10 Specifically, FIG. 1 is a schematic diagram of a three-dimensional axial ratio simulation viewed from the long side where the second radiation branch 12 is arranged.

[0105] See also Figure 11 , is a second three-dimensional axial ratio simulation diagram of the electronic device 100 in some embodiments of the present application. Figure 11The second three-dimensional axial ratio simulation diagram of the electronic device 100 is a three-dimensional axial ratio simulation diagram of planar radiation obtained by simulating the antenna assembly 1 shown in any of the aforementioned embodiments included in the electronic device 100.

[0106] like Figure 11 It can be seen that, viewed from the plane where the display screen 2 of the electronic device 100 is located, the radiation intensity radiated by the antenna assembly 1 in most directions within the plane of the display screen 2 is substantially equal and circular. Consequently, the ratio of the maximum radiation intensity to the minimum radiation intensity is approximately 1, and a low axial ratio is achieved in the plane where the display screen 2 of the electronic device 100 is located. Consequently, the electronic device 100 achieves good vertical orthogonal polarization.

[0107] The electronic device 100 includes at least one antenna assembly 1. That is, the electronic device 100 may include one or more antenna assemblies 1.

[0108] See also Figure 12 , is another plan view of the electronic device 100 in some embodiments of the present application. Figure 12 As shown, the electronic device 100 may include two antenna assemblies 1 , wherein each antenna assembly 1 includes the aforementioned structure.

[0109] like Figure 12 As shown, one antenna assembly 1 is arranged at the upper left corner of the electronic device 100, and the other antenna assembly 1 is arranged at the lower right corner of the electronic device 100. Figure 12 Position in the perspective shown.

[0110] like Figure 12 As shown, the first radiation branch 11 of the antenna assembly 1 located at the upper left corner of the electronic device 100 is a metal segment of the frame 10 set on the first side B1 of the electronic device 100, the second radiation branch 12 is a metal segment of the frame 10 set on the second side B2 of the electronic device 100, the first side B1 and the second side B2 are adjacent sides, and the feeding excitation branch 13 is a metal segment of the frame 10 placed at the top corner between the first side B1 and the second side B2 of the electronic device 100.

[0111] The first radiation branch 11 of the antenna assembly 1 located at the lower right corner of the electronic device 100 is a metal segment of the frame 10 set on the third side B3 of the electronic device 100, and the second radiation branch 12 is a metal segment of the frame 10 set on the fourth side B4 of the electronic device 100. The third side B3 and the fourth side B4 are adjacent sides, and the feeding excitation branch 13 is a metal segment of the frame 10 placed at the top corner between the third side B3 and the fourth side B4 of the electronic device 100.

[0112] Among them, such as Figure 12 As shown, in some embodiments, the first side B1 is the short side located at the top of the electronic device 100, the third side B3 is the short side located at the bottom of the electronic device 100, the second side B2 is the long side located on the left side of the electronic device 100, and the fourth side B4 is the long side located on the right side of the electronic device 100.

[0113] In some embodiments, one of the two antenna assemblies 1 can support the transmission of satellite communication signals, and the other can support the reception of the same satellite communication signal. For example, the electrical length of the feed excitation branch 13, the first radiation branch 11, and the second radiation branch 12 of one antenna assembly is λ1 / 4, λ1 is the transmission frequency of the satellite communication signal, and the electrical length of the feed excitation branch 13, the first radiation branch 11, and the second radiation branch 12 of the other antenna assembly is λ2 / 4, λ2 is the reception frequency of the satellite communication signal, so that they can resonate at the transmission frequency and reception frequency of the satellite communication signal, respectively, and support the transmission and reception of satellite communication signals, respectively. In some embodiments, the two antenna assemblies 1 support the same satellite communication signal, for example, both are Beidou satellite communication signals, and one of them can support the transmission of satellite communication signals, and the other can support the reception of the same satellite communication signal. Therefore, in some embodiments, when the electronic device 100 includes two antenna assemblies 1 at the same time, one of them can be used as a transmitting antenna and the other can be used as a receiving antenna, which can realize dual-frequency circular polarization or dual-frequency elliptical polarization under the same satellite communication system, thereby realizing the transmission and reception of satellite communication signals at the same time.

[0114] In some embodiments, the two antenna assemblies 1 may also include the aforementioned first tuning unit 14, second tuning unit 15, and third tuning unit 16, each capable of supporting the transmission and reception of satellite communication signals, and capable of supporting the transmission and reception of different satellite communication signals respectively. For example, one antenna assembly 1 can support the transmission and reception of a first satellite communication signal, and the other antenna assembly 1 can support the transmission and reception of a second satellite communication signal. Therefore, one antenna assembly 1 independently supports the transmission and reception of a first satellite communication signal, and the other antenna assembly 1 independently supports the transmission and reception of a second satellite communication signal, thereby realizing dual-frequency circular polarization or dual-frequency elliptical polarization under different satellite communication systems. Thus, at the same time, the antenna assembly 1 can simultaneously transmit or receive the first satellite communication signal, and transmit or receive the second satellite communication signal, thereby effectively improving the performance and reliability of satellite communication. The first satellite communication signal may be a Beidou satellite communication signal, and the second satellite communication signal may be a satellite communication signal of another satellite communication system.

[0115] Obviously, in other embodiments, the electronic device 100 may also include 3 antenna components 1, or even 4 antenna components 1. For example, an antenna component 1 may be provided at the upper left corner, upper right corner, lower left corner, and lower right corner of the electronic device 100, respectively.

[0116] When the frame 10 of the electronic device 100 is a metal frame, the first radiation branch 11, the second radiation branch 12 and the feeding excitation branch 13 of each antenna assembly 1 are metal frame segments formed by opening a gap F1 in the metal frame of the electronic device 100.

[0117] When the frame 10 of the electronic device 100 is a non-metallic frame, the first radiation branch 11, the second radiation branch 12 and the feed excitation branch 13 of each antenna component 1 are metal segments arranged in the frame 10 of the electronic device 100, for example, they are metal segments embedded in the frame 10 of the electronic device 100, or they are metal segments arranged on the inner side of the frame 10 of the electronic device 100.

[0118] See also Figure 13 , is a further structural block diagram of the electronic device 100 in some embodiments of the present application. Figure 13As shown, the electronic device 100 includes the antenna assembly 1 and the processor 4. When the antenna assembly 1 further includes the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16, the processor 4 is connected to the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16, and is further configured to control the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 to be enabled or disabled.

[0119] For example, in some embodiments, the original electrical length of the feed excitation branch 13, the first radiation branch 11, and the second radiation branch 12 is λ1 / 4, where λ1 is the wavelength corresponding to the transmission frequency of the satellite communication signal. That is, in some embodiments, the electrical lengths of the feed excitation branch 13, the first radiation branch 11, and the second radiation branch 12 are mainly designed based on the realization of the transmission of the satellite communication signal. Therefore, when transmitting the satellite communication signal, the electrical lengths of the feed excitation branch 13, the first radiation branch 11, and the second radiation branch 12 have met the requirements. At this time, the processor 4 controls the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 to be disabled. When receiving satellite communication signals, the processor 4 controls the first tuning unit 14, the second tuning unit 15 and the third tuning unit 16 to be enabled, so that the electrical length of the feed excitation branch 13, the first radiation branch 11 and the second radiation branch 12 is adjusted to λ2 / 4, where λ2 is the wavelength corresponding to the receiving frequency of the satellite communication signal, thereby supporting the reception of satellite communication signals.

[0120] As described above, the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 each include a tuning element X1 and a tuning switch W1 connected in parallel between the corresponding ground point and the ground. In some embodiments, the processor 4 is specifically configured to control the tuning switches W1 in the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 to be turned on when transmitting a satellite communication signal, and to short-circuit the branch containing the corresponding tuning element X1, thereby disabling the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 when transmitting a satellite communication signal. The processor 4 is also configured to control the tuning switches W1 in the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 to be turned off when receiving a satellite communication signal, and to connect the branch containing the corresponding tuning element X1, thereby enabling the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 when receiving a satellite communication signal.

[0121] In other embodiments, the original electrical length of the feed excitation branch 13, the first radiation branch 11, and the second radiation branch 12 is λ2 / 4, where λ2 is the wavelength corresponding to the transmission frequency of the satellite communication signal. That is, in other embodiments, the electrical length of the feed excitation branch 13, the first radiation branch 11, and the second radiation branch 12 is mainly designed based on achieving the reception of the satellite communication signal. Therefore, when receiving the satellite communication signal, the electrical length of the feed excitation branch 13, the first radiation branch 11, and the second radiation branch 12 has met the requirements. At this time, the processor 4 controls the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 to be disabled. When transmitting satellite communication signals, the processor 4 controls the first tuning unit 14, the second tuning unit 15 and the third tuning unit 16 to be enabled, so that the electrical length of the feed excitation branch 13, the first radiation branch 11 and the second radiation branch 12 is adjusted to λ1 / 4, where λ1 is the wavelength corresponding to the receiving frequency of the satellite communication signal, thereby supporting the transmission of satellite communication signals.

[0122] Similarly, the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 each include a tuning element X1 and a tuning switch W1 connected in parallel between the corresponding ground point and the ground. In some embodiments, the processor 4 is specifically configured to control the tuning switches W1 in the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 to be turned on when receiving satellite communication signals, and to short-circuit the branch where the corresponding tuning element X1 is located, thereby disabling the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 when receiving satellite communication signals. The processor 4 is also configured to control the tuning switches W1 in the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 to be turned off when transmitting satellite communication signals, and to connect the branch where the corresponding tuning element X1 is located, thereby enabling the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16 when transmitting satellite communication signals.

[0123] The tuning switch W1 can be a transistor such as a MOS transistor or a triode, and the processor 4 controls the tuning switch W1 to be turned on or off by outputting a corresponding level signal. For example, when the tuning switch W1 is a MOS transistor, the processor 4 is connected to the gates of all NMOS transistors of the first tuning unit 14, the second tuning unit 15, and the third tuning unit 16, and outputs a corresponding high-level or low-level signal as needed to control the tuning switch W1 to be turned on or off, or turned on or off.

[0124] The processor 4 may be a central processing unit, a microcontroller, a single chip microcomputer, a digital signal processor, etc.

[0125] The electronic device 100 of the present application may be any electronic device with an antenna, such as a mobile phone, a tablet computer, etc. The electronic device 100 may also include other components, which are irrelevant to the improvement of the present invention and are not described in detail.

[0126] The antenna assembly 1 and electronic device 100 of the present application, the feed excitation branch 13 of the antenna assembly 1 is coupled with the first radiation branch 11 and the second radiation branch 12 respectively through electric coupling and magnetic coupling, so that the phase difference between the two coupled feed signals obtained after the feed signal received by the feed excitation branch 13 is 90° after electric coupling and magnetic coupling, and because the first radiation branch 11 and the second radiation branch 12 are arranged at an angle, the first radiation branch 11 and the second radiation branch 12 have circular polarization radiation characteristics or elliptically polarized radiation characteristics, so that the reception and / or transmission of satellite communication signals can be achieved through a simple and compact structure. The electronic device 100 can achieve the transmission and / or reception of satellite communication signals by being equipped with the antenna assembly 1 with a simple and compact structure as described above, which can make the overall volume of the electronic device 100 small and easy to carry.
