[0030] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0031] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0033] It is understood that the terms "first" and "second" used in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] It is understood that the term "connection" in the following embodiments should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have electrical signal or data transmission with each other.

[0035] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0036] Taking mobile phones as an example, in 5G mobile phone antenna solutions, the GPS frequency band is usually designed on the same antenna as the 5G high-frequency band, such as the N78 band, and is located at the top of the phone. The long stub of the antenna serves as the radiating stub for the GPS L1 (1575.42MHz) band, and the short stub serves as the radiating stub for the New Radio (NR) high-frequency band, such as the N78 (3.3GHz-3.8GHz). The GPS antenna is typically a linearly polarized antenna, and its placement at the top of the phone is to achieve higher antenna performance. However, in these technologies, linearly polarized GPS antennas experience a 3dB polarization mismatch loss when receiving GPS signals, leading to reduced GPS antenna reception performance in areas with poor signal strength, hindering accurate positioning. On the other hand, when high-frequency NR bands such as the N78 band are designed with the GPS band on the same antenna, the N78 band has shorter radiating branches, resulting in more concentrated energy. The antenna's SAR value often exceeds the Federal Communications Commission's (FCC) SAR control standards. Therefore, the air interface performance of the N78 band cannot be guaranteed in 4G and 5G dual connectivity (ENDC, EUTRA NR Dual-Connectivity) scenarios or joint-mode scenarios. ENDC is an abbreviation for EUTRA NR Dual-Connectivity; E stands for E-UTRA, which is the air interface of 3GPP LTE, version 8 of 3GPP; N stands for N Radio 5G; and D stands for LTE and 5G dual connectivity. ENDC can be understood as mutual compatibility between 4G and 5G dual connectivity.

[0037] The ideal condition for GPS communication is circular polarization. Circular polarization occurs when the angle between the polarization plane of a radio wave and the Earth's normal plane changes periodically from 0° to 360°, meaning the electric field magnitude remains constant while its direction changes over time, and the trajectory of the electric field vector's endpoint projects as a circle onto a plane perpendicular to the propagation direction. Electromagnetic waves with a fixed orientation of their electric field vector in space are called linearly polarized waves. In other words, theoretically, a circularly polarized GPS antenna receives a stronger signal than a linearly polarized GPS antenna. To improve GPS positioning accuracy while ensuring that the SAR value meets international safety regulations, this application provides an antenna assembly, such as... Figure 1 As shown, it includes a first radiator 10, a second radiator 20, a phase shifter 30, and a feed source 40; wherein,

[0038] The first radiator 10 and the second radiator 20 do not intersect, but their respective length extensions are orthogonal (perpendicular);

[0039] Phase shifting device 30 is used to connect the first radiator 10 and the second radiator 20, such that the currents on the first radiator 10 and the second radiator 20 are 90 degrees out of phase.

[0040] The feed source 40 is connected to the phase shifter 30 and is used to excite the first radiator 10 and the second radiator 20 to operate in the GPS frequency band in the quarter-wavelength mode and to excite the first radiator 10 and the second radiator 20 to operate in the NR high-frequency band in the three-quarter-wavelength mode.

[0041] The antenna assembly provided in this application embodiment has a 90-degree phase difference between the currents on the first radiator 10 and the second radiator 20, achieving circular polarization radiation. This makes the antenna assembly compatible with circularly polarized GPS band antennas, such as GPS L1 band antennas, and 5G high-frequency band antennas, such as N78 band antennas. Through the circularly polarized GPS antenna of this application embodiment, satellite positioning signals are acquired more effectively, enabling the electronic device containing the antenna assembly to have more accurate and faster positioning capabilities, thus improving GPS positioning accuracy. Simultaneously, the 5G high-frequency band antenna provided in this application embodiment has a uniform current hotspot distribution, resulting in lower SAR for the electronic device and meeting international safety regulations.

[0042] In one exemplary instance, such as Figure 2 As shown, the phase-shifting device 30 may include lumped devices such as capacitors or inductors. One end of the lumped device is connected to one end of the first radiator 10, and the other end is connected to one end of the second radiator 20. Here, the values ​​of the lumped devices such as capacitors or inductors can be obtained in advance based on actual application scenarios. The specific values ​​are not used to limit the scope of protection of this application. The emphasis here is on using lumped devices such as capacitors or inductors to adjust the phase of the current on the first radiator 10 and the second radiator 20 of the antenna assembly to make them 90 degrees out of phase. Both capacitors and inductors connected in the circuit have phase-shifting functions. The voltage at the end of the capacitor lags behind the current by 90 degrees, and the voltage at the end of the inductor leads the current by 90 degrees. This is the result of the phase shifting of the capacitor and inductor. In this embodiment, by utilizing the characteristic that the voltage and current at the ends of the capacitor or inductor are 90 degrees out of phase, the current on the first radiator 10 and the second radiator 20 of the antenna assembly are 90 degrees out of phase, thereby realizing the circularly polarized radiation of the antenna assembly. In one embodiment, the lumped device includes a capacitor connected in series between one end of the first radiator 10 and one end of the second radiator 20. In one embodiment, the capacitor may be 1 pF. In one embodiment, such as Figure 2 As shown, the feed 40 is connected to the connection point A of the second radiator 20. Connection point A is the connection point where the lumped device is connected to the first radiator 10 or a connection point near the connection point where the first radiator 10 is connected to the lumped device.

[0043] In one exemplary instance, such as Figure 3As shown, the phase-shifting device 30 may include a phase-shifting stub, one end of which is connected to the first radiator 10 and the other end to the second radiator 20. Here, the length of the phase-shifting stub can be pre-determined based on actual application scenarios; the specific value is not intended to limit the scope of protection of this application. The emphasis here is on using the phase-shifting stub to adjust the current phase on the first radiator 10 and the second radiator 20 of the antenna assembly to a 90-degree phase difference. In this embodiment, an unbalanced feed is used on the phase-shifting stub to form a 90-degree phase shifter, making the current magnitudes on the first radiator 10 and the second radiator 20 of the antenna assembly equal and their phases 90 degrees apart, thereby achieving circular polarization of the antenna assembly. In one embodiment, as... Figure 3 As shown, the feed 40 is connected to the phase-shifting stub at connection point A, so that unbalanced feeding is used on the phase-shifting stub to make the current on the first radiator 10 and the second radiator 20 equal in magnitude and 90 degrees out of phase.

[0044] In one exemplary instance, the antenna assembly provided in this application embodiment is not only applicable to mobile phone antennas, but also to antennas of other terminal products such as Pads, PCs, large-screen devices, etc.

[0045] In one exemplary instance, the antenna component provided in this application may be implemented in forms including, but not limited to, microstrip disk antenna (MDA), flexible printed circuit board (FPC) antenna, laser direct structuring (LDS) antenna, etc.

[0046] In one exemplary instance, by adjusting the arm length of the antenna assembly, the two radiators in the antenna assembly, namely the first radiator 10 and the second radiator 20, can operate in the GPS L1 band in a quarter-wavelength mode, while simultaneously stimulating the first radiator 10 and the second radiator 20 to operate in the NR high-frequency band in a three-quarter-wavelength mode.

[0047] In one exemplary instance, the NR high-frequency band may include, for example, the N78 band, the N77 band, etc.

[0048] In one embodiment, taking the N78 band as an example of the NR high-frequency band, the reflection coefficient S11 curve of the antenna assembly in this embodiment is as follows: Figure 4 As shown, the horizontal axis represents frequency (in GHz), and the vertical axis represents return loss characteristics (in dB). Figure 4 In the diagram, triangle 1 corresponds to the GPS L1 frequency band, and triangle 2 corresponds to the N78 frequency band. Figure 5This is a schematic diagram showing the relationship between the axial ratio of the antenna assembly used as a GPS L1 antenna in an embodiment of this application and frequency. The horizontal axis represents frequency (in GHz), and the vertical axis represents axial ratio (in dB). Figure 5 As shown, the antenna assembly provided in this application embodiment has an axial ratio of less than 3dB in the GPS L1 band and exhibits good circularly polarized radiation characteristics. Figures 6(a) and 6(b) are schematic diagrams of the current distribution of the antenna assembly as an N78 antenna and as a GPS L1 antenna, respectively. As shown in Figure 6(b), it can be seen from the current distribution diagram in the N78 band that when the antenna assembly operates in the N78 band, the current hotspots on the antenna are relatively dispersed. When the input antenna power is constant, the more dispersed the current hotspots are, the lower the SAR value. Therefore, the SAR value of the antenna assembly provided in this application embodiment operating in the N78 band is sufficiently low, meeting international safety regulations. Moreover, as Figure 7 As shown, the antenna assembly provided in this application embodiment has high antenna radiation efficiency, whether it is used as an N78 antenna or a GPS L1 antenna.

[0049] The antenna assembly provided in this application is compatible with circularly polarized GPS band antennas, such as those in the GPS L1 band, and 5G high-frequency band antennas, such as those in the N78 band. Through the circularly polarized GPS antenna of this application, satellite positioning signals are acquired more effectively, enabling electronic devices to have more accurate and faster positioning capabilities and improving GPS positioning accuracy. Furthermore, in the antenna assembly provided in this application, the 5G high-frequency band antenna exhibits a three-quarters radiation mode of the two antenna radiators included in the antenna assembly, with uniform current hotspot distribution and lower SAR, meeting international safety regulations. In one embodiment, the antenna assembly provided in this application has good circularly polarized radiation performance in the GPS L1 band and good radiation performance in the N78 band, while also possessing a lower SAR value.

Simultaneously, in the electronic device provided in this application embodiment, the current hotspot distribution of the 5G high-frequency band antenna is uniform, resulting in lower SAR and meeting international safety regulations.

[0060] It should be noted that, Figure 10The positions of the antenna assembly 100 shown on the electronic device 1000 are merely examples and are not intended to limit the positions of the antenna assemblies provided in the embodiments of this application on the electronic device.

[0061] In one exemplary instance, such as Figure 11 As shown, the phase-shifting device 30 may include a lumped device 30 such as a capacitor or inductor.

Here, the value of the lumped device such as the capacitor or inductor can be obtained in advance according to the actual application scenario.

The emphasis here is on using the lumped device 30 such as the capacitor or inductor to adjust the phase of the current on the first radiator 10 and the second radiator 20 of the antenna assembly to make them 90 degrees out of phase. In this embodiment, the characteristic of a 90-degree phase difference between the voltage and current across the capacitor or inductor is used to make the phase difference of the current on the first radiator 10 and the second radiator 20 90 degrees, thereby realizing the circularly polarized radiation of the antenna assembly 100.
