Referring to fig. 1, fig. 1 is a first structural schematic diagram of an electronic device 10 according to an embodiment of the present disclosure. The electronic device 10 or antenna arrangement may include at least a first antenna 110. The first antenna 110 may include a first radiator 111, a second radiator 112, a first feed 113, and an adjustment circuit 114.

The first radiator 111 and the second radiator 112 may be disposed opposite to each other such that a first coupling gap 101 is formed between one end of the first radiator 111 and one end of the second radiator 112, and the other end of the first radiator 111 and the other end of the second radiator 112 may extend in opposite directions and be grounded. The first feed 113 may be directly or indirectly electrically connected to the first radiator 111, and at least a portion of the adjusting circuit 114 may be directly or indirectly electrically connected between the first feed 113 and the first radiator 111.

The first radiator 111 and the second radiator 112 may be antenna radiators made of conductive materials, such as metal, conductive silver paste material, and the like. As shown in fig. 1, the first radiator 111 may include a first free end (not shown), a first ground 1111 and a first feeding end (not shown), the first free end may be an end close to the first coupling gap 101, the first free end may be spaced apart from the second radiator 112, the first ground 1111 may extend toward a direction away from the second radiator 112, the first ground 1111 may be an end away from the first coupling gap 101, the electronic device 10 or the antenna apparatus may further include a ground plane 200, and the first ground 1111 may be electrically connected to the ground plane 200 to ground the first radiator 111. The first feeding end may be disposed between the first free end and the first ground end 1111. The first feed terminal may be directly or indirectly electrically connected with the first feed 113, and the first feed 113 may provide an excitation current to the first radiator 111 so that the first radiator 111 may perform transmission and reception of wireless signals.

The second radiator 112 may include a second free end (not shown), a second ground end 1121 and a second feeding end (not shown), the second free end may be an end close to the first coupling gap 101, the second free end may be opposite to the first radiator 111, the second ground end 1121 may extend in a direction away from the first radiator 111, the second ground end 1121 may be an end away from the first coupling gap 101, and the second ground end 1121 may be electrically connected to the ground plane 200, so as to implement grounding of the second radiator 112. The second feeding end may be disposed between the second free end and the second ground end 1121. The first radiator 111 and the second radiator 112 may form an aperture-to-aperture antenna.

It is understood that the first radiator 111 may have other feeding terminals besides the first free end, the first ground terminal 1111 and the first feeding terminal, so as to electrically connect the first radiator 111 to other electronic devices. Similarly, other feeding terminals may also be disposed on the second radiator 112 to electrically connect the second radiator 112 to other electronic devices. This is not limited in the embodiments of the present application.

The first feed 113 may be provided on the circuit board 500 of the electronic device 10 or the antenna arrangement, and the first feed 113 may also be provided on the other small board 600 of the electronic device 10 or the antenna arrangement. The first feed 113 may be directly or indirectly electrically connected to the first radiator 111, the first feed 113 may feed an excitation signal into the first radiator 111, and at least a portion of the excitation signal may flow between the first radiator 111 and the ground plane 200, so that the first radiator 111 may transmit and receive a wireless signal to a free space. At least a portion of the excitation signal may also be coupled to the second radiator 112 through the first coupling gap 101 and flow on the second radiator 112, such that the second radiator 112 may also transmit and receive wireless signals to free space.

The conditioning circuit 114 may condition the excitation signal provided by the first feed 113, which may include, but is not limited to, short circuit effects, open circuit effects, equivalent resistive effects, equivalent capacitive effects, coupled feed effects, direct feed effects, and the like.

For example, referring to fig. 1 and fig. 2, fig. 2 is a first current schematic diagram of the electronic device 10 shown in fig. 1, when the first feed 113 provides the first excitation signal I1, at least a portion of the first excitation signal I1 (most of the first excitation signal I1 may excite the first radiator 111 to form a first resonance, and a very small amount of the first excitation signal I1 may pass through the first feed 113, the adjusting circuit 114, and so on, and the specific flow form of the first excitation signal I1 and other excitation signals is not limited in this embodiment of the present application) may pass through the adjusting circuit 114 and under the action of the adjusting circuit 114, enable the first radiator 111 to realize the first resonance and support transmission and reception of the first wireless signal.

Referring to fig. 3 in conjunction with fig. 1, fig. 3 is a second current schematic diagram of the electronic device 10 shown in fig. 1, when the first feed 113 provides the second excitation signal I2, at least a portion of the second excitation signal I2 (most of the second excitation signal I2 can excite the second radiator 112 to form the second resonance, and a very small amount of the second excitation signal I2 can be fed back through the first feed 113, the adjusting circuit 114, the first ground terminal 1111 of the first radiator 111, and the like, in this embodiment, the specific flowing manner of the second excitation signal I2 is not limited), and the second excitation signal I3832 can be coupled to the second radiator 112 through the first coupling gap 101 and make the second radiator 112 implement the second resonance through the adjusting circuit 114, and the second radiator 112 can support transmission and reception of the second wireless signal under the effect of the second resonance.

It will be appreciated that the second resonance may be different from the first resonance, such that the second wireless signal may be different from the first wireless signal. For example, the center frequency point of the first resonance may be different from the center frequency point of the second resonance; correspondingly, the frequency of the first wireless signal may be different from the frequency of the second wireless signal. Moreover, the frequency of the first wireless signal may be far from the frequency of the second wireless signal, so that the first radiator 111 does not easily interfere with the second wireless signal supported by the second radiator 112 when supporting the first wireless signal.

It is understood that the first feed 113 may separately feed the first excitation signal I1 to the first radiator 111, so that the first radiator 111 realizes the first resonance; the first feed 113 may also feed the second excitation signal I2 to the first radiator 111 separately, so that the second radiator 112 may realize a second resonance; the first feed 113 may also feed the first radiator 111 with the first excitation signal I1 and the second excitation signal I2 (e.g., carrier aggregation signals of the first excitation signal I1 and the second excitation signal I2) at the same time, so that the first radiator 111 realizes the first resonance and the second radiator 112 realizes the second resonance.

It is understood that the first excitation signal I1 and the second excitation signal I2 may be signals of different frequencies, such that the first resonance may be different from the second resonance. Of course, the first excitation signal I1 and the second excitation signal I2 may be the same signal, but after being adjusted by the adjusting circuit 114, the excitation signal may realize a first resonance when passing through the first radiator 111 and a second resonance when being coupled to the second radiator 112 through the first coupling gap 101, so that the first radiator 111 and the second radiator 112 may form different resonances even though the same excitation signal is fed. The embodiment of the present application does not limit the specific forming manner of the first driving signal I1 and the second driving signal I2.

It is understood that the stub length of the first radiator 111 may be different from the stub length of the second radiator 112, so that the center frequencies of the first resonance and the second resonance are different. Of course, the length of the branch of the first radiator 111 may be the same as that of the branch of the second radiator 112, but after the adjustment of the adjusting circuit 114, the effective electrical length of the first radiator 111 at the first resonance may be different from that of the second radiator 112 at the second resonance. It is understood that the effective electrical length refers to the length of the radiator when radiating a signal, and the effective electrical length of the radiator may be greater than, less than, or equal to the length of its stub.

In the electronic device 10 of the embodiment of the application, the first excitation signal I1 provided by the first feed 113 is acted by the adjusting circuit 114 to enable the first radiator 111 to realize the first resonance, and the first antenna 110 may support the first wireless signal; the second excitation signal I2 provided by the first feed 113 may be coupled to the second radiator 112 through the first coupling gap 101 by the adjusting circuit 114, so that the second radiator 112 may realize a second resonance, and the first antenna 110 may also support a second wireless signal. Therefore, the electronic device 10 of the present application can support two wireless signals through one first feed source 113, and the electronic device 10 does not need to be provided with two feed sources, so that not only can the production cost be saved, but also the miniaturization design of the electronic device 10 can be realized. Meanwhile, the first wireless signal is supported by the first radiator 111, and the second wireless signal is supported by the second radiator 112, which may be transmitted simultaneously without mutual interference, so that the antenna performance of the electronic device 10 is better.

The adjusting circuit 114 may also adjust other excitation signals provided by the first feed 113 so that the first antenna 110 can support other wireless signals.

Illustratively, when the first feed 113 provides the third excitation signal I3, at least a portion of the third excitation signal I3 (explained above with reference to the first excitation signal I1 and the second excitation signal I2) may enable the first radiator 111 to achieve a third resonance under the action of the adjusting circuit 114, and the third excitation signal I3 may be mainly supported by the first radiator 111, and the first radiator 111 may support a third wireless signal under the action of the third resonance.

As another example, when the fourth excitation signal I4 is provided by the first feed 113, at least a portion of the fourth excitation signal I4 (explained above with reference to the first excitation signal I1 and the second excitation signal I2) enables the first radiator 111 to realize a fourth resonance under the action of the adjusting circuit 114, and the fourth excitation signal I4 may be mainly supported by the first radiator 111, and the first radiator 111 may support a fourth wireless signal under the action of the fourth resonance.

It is to be understood that the first resonance, the second resonance, the third resonance, and the fourth resonance may be different from each other such that the first wireless signal, the second wireless signal, the third wireless signal, and the fourth wireless signal are different from each other. For example, the second resonance may support a second wireless signal of an N78 frequency band (3.3GHz to 3.8GHz) or a B78 frequency band (3.3GHz to 3.8 GHz). The first resonance may support a first wireless signal of an N28 frequency band (703MHz to 803MHz), a B28 frequency band (703MHz to 803MHz), an N3 frequency band (1.71GHz to 1.88GHz), a B3 frequency band (1.71GHz to 1.88GHz), an N41 frequency band (2.496GHz to 2.69GHz), or a B41 frequency band (2.496GHz to 2.69 GHz); the third resonance can also support a third wireless signal of an N28 frequency band, a B28 frequency band, an N3 frequency band, a B3 frequency band, an N41 frequency band or a B41 frequency band; the fourth resonance may also support a fourth wireless signal in an N28 frequency band, a B28 frequency band, an N3 frequency band, a B3 frequency band, an N41 frequency band, or a B41 frequency band, but the frequencies or frequency bands of signals supported by the first resonance, the third resonance, and the fourth resonance are different. For example, when the stub length of the first radiator 111 is greater than the stub length of the second radiator 112, the first resonance may support an N28 band signal, the second resonance may support an N78 band signal, the third resonance may support a B3 band signal, and the fourth resonance may support an N41 band signal.

It is to be appreciated that the first feed 113 may provide the first driving signal I1, the second driving signal I2, the third driving signal I3 or the fourth driving signal I4 separately; alternatively, the first feed 113 may also provide two or more of the first driving signal I1, the second driving signal I2, the third driving signal I3, and the fourth driving signal I4 at the same time. This is not limited in the embodiments of the present application.

It is to be understood that it is considered that the first resonance, the third resonance, and the fourth resonance are all supported by the first radiator 111, and thus, the effective electrical lengths of the first radiator 111 when the first resonance, the third resonance, and the fourth resonance are achieved may be different.

It can be understood that when the first radiator 111 implements the first resonance, the third resonance, and the fourth resonance, the first radiator 111 may be in an Inverted F Antenna (IFA) mode at a wavelength of 1/4. When the second radiator 112 realizes the second resonance, the second radiator 112 may also be in the IFA mode of 1/4 wavelengths.

Please refer to fig. 4, wherein fig. 4 is a second structural schematic diagram of the electronic device 10 according to an embodiment of the present disclosure. The present embodiment provides an adjusting circuit 114, and the adjusting circuit 114 can adjust to make the effective electrical lengths of the first radiator 111 and the second radiator 112 different when they support different resonances. The conditioning circuit 114 may include, but is not limited to, a first matching circuit 1141 and a first filtering circuit 1142.

The first matching circuit 1141 may be connected in series between the first feed 113 and the first radiator 111. One end of the first matching circuit 1141 may be directly or indirectly electrically connected to the first feed 113, and the other end of the first matching circuit 1141 may be directly or indirectly electrically connected to the first radiator 111. One end of the first filter circuit 1142 may be connected in parallel between the first feed 113 and the first radiator 111, and the other end of the first filter circuit 1142 may be electrically connected to the ground plane 200 directly or indirectly to achieve grounding. The first filter circuit 1142 may form an equivalent capacitance or an equivalent inductance under the action of the excitation signal provided by the first feed 113, so as to change the electrical length of the first radiator 111 or the second radiator 112. The first matching circuit 1141 may form an equivalent capacitance or an equivalent inductance under the action of the excitation signal provided by the first feed 113, so as to correspondingly couple or directly feed the excitation signal provided by the first feed 113 to the first radiator 111.

For example, please refer to fig. 5 in combination with fig. 4, and fig. 5 is a first equivalent circuit and a current schematic diagram of the electronic device 10 shown in fig. 4. When the first feed 113 provides the first excitation signal I1, for example, a signal of N28 band/B28 band, the first filter circuit 1142 may form a first equivalent capacitor C1 for equivalently increasing the effective electrical length of the first radiator 111; meanwhile, the first matching circuit 1141 may form a second equivalent capacitance C2 for coupling feeding; at least a portion of the first excitation signal I1 may cause the first radiator 111 to achieve the first resonance and support the first wireless signal under the action of the adjusting circuit 114. For example, the first radiator 111 may support a first wireless signal of the N28 band/B28 band.

Referring to fig. 6 in conjunction with fig. 4, fig. 6 is a second equivalent circuit and a current schematic diagram of the electronic device 10 shown in fig. 4. When the first feed 113 provides the second excitation signal I2, for example, a signal of N78 band/B78 band, the first filter circuit 1142 may form a first equivalent inductance L1 for equivalently reducing the effective electrical length of the first radiator 111; meanwhile, the first matching circuit 1141 may form a second equivalent inductance L2 for direct feeding; the second radiator 112 may support a second wireless signal of the N78 band/B78 band.

For another example, please refer to fig. 7 in combination with fig. 4, and fig. 7 is a third equivalent circuit and a current schematic diagram of the electronic device 10 shown in fig. 4. When the first feed 113 provides the third excitation signal I3, for example, a B3 band/N3 band signal, the first filter circuit 1142 may form a third equivalent inductor L3 for equivalently reducing the length of the first radiation branch; meanwhile, the first matching circuit 1141 may form a third equivalent capacitor C3 for coupling feeding; the first radiator 111 may support the third wireless signal of the B3 band/N3 band.

Referring to fig. 8 in conjunction with fig. 4, fig. 8 is a fourth equivalent circuit and current diagram of the electronic device 10 shown in fig. 4. When the first feed 113 provides the fourth excitation signal I4, for example, a signal of N41 band/B41 band, the first filter circuit 1142 may form a fourth equivalent inductor L4 for equivalently reducing the length of the first radiation branch; meanwhile, the first matching circuit 1141 may form a fifth equivalent inductance L5 for direct feeding; the first radiator 111 may support a fourth wireless signal of the N41 band/B41 band.

It is to be understood that the capacitance values of the equivalent capacitors may be the same or different, or may be partially the same or partially different. Similarly, the inductance values of the equivalent inductors may be the same or different, or may be partially the same or partially different. The embodiment of the present application does not limit the specific capacitance and inductance of the equivalent capacitor and the equivalent inductor.

Please refer to fig. 9 and 10 in combination with fig. 4 to 8, in which fig. 9 is a graph of an S parameter of the first antenna 110 shown in fig. 4, and fig. 10 is a graph of a radiation performance of the first antenna 110 shown in fig. 4. The curve S1 in fig. 9 is a reflection coefficient curve of the first antenna 110 operating in the N28, B3 receiving band, N41 and N78 band. Curves S2 and S3 in fig. 10 show the radiation efficiency and the system frequency of the first antenna 110 in the above frequency bands, respectively. From the curves S1 to S3, the average system efficiency of the first antenna 110 is about-11.5 dB in the N28 receiving band, about-4.8 dB in the B3 receiving band, about-4 dB in the N41 receiving band, and about-3.8 dB in the N78 receiving band. The first antenna 110 has superior radiation performance.

As shown in fig. 4 to 8, the adjusting circuit 114 may further include a switching circuit 1143, the switching circuit 1143 may include one or more branches therein, and the switching circuit 1143 may be switched to different branches according to different functions of the first filter circuit 1142 and the first matching circuit 1141, so as to increase or decrease the electrical length of the second radiator 112 and enable the first antenna 110 to form the first resonance to the fourth resonance, for example, the first radiator 111 may form the first resonance, the third resonance or the fourth resonance, and the second radiator 112 may implement the second resonance. It should be noted that the adjusting circuit 114 may include the switching circuit 1143, or may not include the switching circuit 1143; of course, the adjusting circuit 114 may also include other circuits, and the specific structure of the adjusting circuit 114 in the embodiment of the present application is not limited.

It is understood that the first filter circuit 1142, the first matching circuit 1141, and the switching circuit 1143 may include, but are not limited to, a circuit formed by any series connection or any parallel connection of a capacitor, an inductor, and a resistor.

For example, referring to fig. 11, fig. 11 is a schematic electrical connection diagram of the adjusting circuit 114 according to an embodiment of the present disclosure. The first filter circuit 1142 may include a first capacitor C4, a second capacitor C5, and a first inductor L6, the second capacitor C5 may be connected in parallel with the first inductor L6 to form a whole, the first capacitor C4 may be connected in series with the whole formed by connecting the second capacitor C5 and the first inductor L6 in parallel, and the other end of the whole formed by connecting the second capacitor C5 and the first inductor L6 in parallel may be grounded. The first matching circuit 1141 may include a third capacitor C6 and a second inductor L7, and the third capacitor C6 and the second inductor L7 may be connected in series.

It should be noted that the structures of the first filter circuit 1142 and the first matching circuit 1141 are not limited to this, for example, the first filter circuit 1142 and the first matching circuit 1141 may further include, but not limited to, one or more capacitors, inductors, and resistors connected in series or in parallel. This is not limited in the examples of the present application.

It should be noted that, the first matching circuit 1141 according to the embodiment of the present application may form an equivalent capacitance and an equivalent inductance, and may also perform impedance matching on the excitation signal provided by the first feed 113 to adjust frequency points of multiple resonances implemented by the first radiator 111 and the second radiator 112. Similarly, the first filter circuit 1142 may form an equivalent capacitor and an equivalent inductor, and may also open or short the excitation signal, so that the first radiator 111 and the second radiator 112 may realize the resonance. The switching circuit 1143 may change the electrical length of the second radiator 112, and may open, short, and change the capacitance, resistance, and inductance of the second radiator 112, so that the first antenna 110 may realize the above resonance. The functions of the first matching circuit 1141, the first filter circuit 1142, and the switching circuit 1143 are not specifically limited in the embodiment of the present application.

It should be noted that, in addition to respective corresponding resonances of the first radiator 111 and the second radiator 112 in the embodiment of the present application, a certain resonance may be realized together, so that the first radiator 111 and the second radiator 112 may support a wireless signal together.

In the electronic device 10 of the embodiment of the application, the adjusting circuit 114 utilizes the first matching circuit 1141 and the first filter circuit 1142 with different equivalent reactance characteristics in different frequency bands, so that the first radiator 111 and the second radiator 112 can work in the IFA mode of 1/4 wavelengths in different frequency bands, and the first antenna 110 can support the N28 frequency band/B28 frequency band, the B3 frequency band/N3 frequency band, the N41 frequency band/B41 frequency band, and the N78 frequency band/B78 frequency band. The variety of wireless signals supported by the first antenna 110 is greater, and the electronic device 10 may be further miniaturized.

It should be noted that, in addition to the above-mentioned radio signals in the frequency band, the first antenna 110 in the embodiment of the present application may also support radio signals in other frequency bands. And will not be described in detail herein.

Referring to fig. 12, fig. 12 is a schematic structural diagram of a third electronic device 10 according to an embodiment of the present disclosure. The electronic device 10 may further include a first frame 321, a third frame 323, a second frame 322, and a fourth frame 324, which are connected in sequence, where the second frame 322 may be disposed opposite to the first frame 321, the third frame 323 may be disposed opposite to the fourth frame 324, and lengths of the first frame 321 and the second frame 322 may be smaller than lengths of the third frame 323 and the fourth frame 324, so that the first frame 321 and the second frame 322 may be short frames of the electronic device 10, and the third frame 323 and the fourth frame 324 may be long frames of the electronic device 10.

At least most of the radiators (e.g., all of the first radiators 111 and most of the second radiators 112) of the first antenna 110 may be disposed on the first frame 321. For example, the radiator of the first antenna 110 may be directly or indirectly connected to the first frame 321, and at least most of the projection of the first antenna 110 may be located on the first frame 321. For another example, when the first frame 321 is made of a conductive material, at least most of the radiators of the first antenna 110 may be a part of the first frame 321, and at least most of the first antenna 110 may be formed on the first frame 321, so as to implement multiplexing of the first frame 321.

It is understood that the first radiator 111 of the first antenna 110 may be entirely disposed on the first frame 321, at least a portion of the second radiator 112 may be disposed on the first frame 321, and another portion of the second radiator 112 may be disposed on the third frame 323.

As shown in fig. 12, the electronic device 10 or the antenna apparatus may further include a second antenna 120, and the second antenna 120 may be spaced apart from the first antenna 110, or may be directly or indirectly connected to the first antenna 110. At least most of the radiators of the second antenna 120 (e.g., all of the third radiator 121 and part of the fourth radiator 122) may be disposed on the first frame 321. For example, at least most of the radiators of the second antenna 120 may be directly or indirectly connected to the first frame 321, so that the projection thereof may be located on the first frame 321, or may be formed on the first frame 321 to realize multiplexing of the first frame 321.

The second antenna 120 may include a third radiator 121 and a fourth radiator 122, and a second coupling gap 102 may be formed between the third radiator 121 and the fourth radiator 122. The third radiator 121 may include a third free end (not shown) and a third ground 1211, which are oppositely disposed, the third free end may be an end close to the second coupling gap 102, the third free end may be spaced apart from the fourth radiator 122, the third ground 1211 may be an end far from the second coupling gap 102, and the third ground 1211 may be electrically connected to the ground plane 200 to implement grounding of the third radiator 121. The fourth radiator 122 may include a fourth free end (not shown) and a fourth ground terminal 1221, which are oppositely disposed, the fourth free end may be an end close to the second coupling gap 102, the fourth free end may be disposed opposite to the third radiator 121 at a distance, the fourth ground terminal 1221 may be an end far from the second coupling gap 102, and the fourth ground terminal 1221 may be electrically connected to the ground plane 200 to implement grounding of the second radiator 112.

It is understood that all of the third radiators 121 may be disposed on the first frame 321, at least most of the fourth radiators 122 may be disposed on the first frame 321, and another part of the fourth radiators 122 may be disposed on the fourth frame 324.

It is understood that the first antenna 110 and the second antenna 120 may be isolated by a common ground. For example, one end (e.g., the third ground 1211) of the third radiator 121 of the second antenna 120 may coincide with the other end (e.g., the first ground 1111) of the first radiator 111 of the first antenna 110, so that the two are grounded at the first ground 1111 in common. The first ground 1111 may isolate signals supported by the first antenna 110 from signals supported by the second antenna 120.

In the electronic device 10 of the embodiment of the application, most of the radiators of the first antenna 110 and most of the radiators of the second antenna 120 are simultaneously disposed on the short border 320 of the electronic device 10, and the first antenna 110 and the second antenna 120 can reasonably utilize the space of the short border 320 of the electronic device 10, so as to reduce the space occupied by the first antenna 110 and the second antenna 120. Meanwhile, the first antenna 110 and the second antenna 120 are grounded through the same ground terminal, the isolation between the two antennas is high, and the mutual interference is small.

Referring to fig. 13 in conjunction with fig. 12, fig. 13 is an electrical connection diagram of the second antenna 120 shown in fig. 12. The second antenna 120 may also include a second feed 123, a second filter circuit 124, and a third feed 125.

The second feed 123 may be directly or indirectly electrically connected to the third radiator 121, and the second feed 123 may feed an excitation signal to the third radiator 121 so that the third radiator 121 may support a wireless signal. The third feed 125 may be directly or indirectly electrically connected to the fourth radiator 122, and the third feed 125 may feed an excitation signal to the fourth radiator 122 so that the fourth radiator 122 may support a wireless signal. The second filter circuit 124 may be connected in series between the second feed 123 and the third radiator 121, and the second filter circuit 124 may filter the excitation signal passing through it, so that the third radiator 121 and the fourth radiator 122 may support corresponding wireless signals.

For example, please refer to fig. 14 in combination with fig. 13, and fig. 14 is a first current diagram of the second antenna 120 shown in fig. 13. The second feed 123 may provide a fifth driving signal I5, when the second feed 123 feeds the fifth driving signal I5 to the third radiator 121, the second filter circuit 124 may allow the fifth driving signal I5 to pass through, the fifth driving signal I5 may flow from the second feed 123 through the second filter circuit 124 and into the third radiator 121, and the fifth driving signal I5 may excite the third radiator 121 to achieve a fifth resonance and support a fifth wireless signal. The fifth excitation signal I5 does not couple the third radiator 121 with the fourth radiator 122, and the fifth excitation signal I5 hardly flows on the fourth radiator 122.

For another example, please refer to fig. 15 in combination with fig. 13, and fig. 15 is a second current diagram of the second antenna 120 shown in fig. 13. The third feed 125 may provide a sixth driving signal I6, which, when the third feed 125 feeds the sixth driving signal I6 to the fourth radiator 122, the sixth excitation signal I6 may flow from the third feed 125 into the fourth radiator 122, the sixth excitation signal I6 may flow from the fourth radiator 122 to the third radiator 121 through the second coupling gap 102 and flow in the third radiator 121, the second filter circuit 124 may prevent the sixth excitation signal I6 from passing through, the second filter circuit 124 may be open-circuited to the sixth excitation signal I6, at least a portion of the sixth excitation signal I6 (a portion of the sixth excitation signal I6 may flow on the fourth radiator 122 and may return to ground through the fourth ground terminal 1221) may be coupled to the third radiator 121 through the second coupling gap 102, and the sixth excitation signal I6 may excite the fourth radiator 122 and at least a portion of the third radiator 121 to jointly generate a sixth resonance to support the sixth wireless signal. Further, the sixth driving signal I6 does not flow from the second filter circuit 124 to the second feed 123, and the sixth driving signal I6 may be grounded from the third ground 1211 of the third radiator 121 to form a loop.

It is understood that the second filter circuit 124 is open to the sixth driving signal I6, which may mean that at the resonance of the sixth driving signal I6, the resistance of the second filter circuit 124 is infinite to block the sixth driving signal I6 from flowing into the second feed 123.

Based on this, in the electronic device 10 and the antenna apparatus according to the embodiment of the application, the third radiator 121 and the fourth radiator 122 are disposed opposite to each other and provided with the second coupling gap 102, under the cooperation of the second feed 123, the third feed 125 and the second filter circuit 124, the second feed 123 may feed the fifth excitation signal I5 into the third radiator 121, and the third radiator 121 may implement a fifth resonance and support a fifth wireless signal; the third feed 125 may feed a sixth excitation signal I6 to the fourth radiator 122, and the third radiator 121 and the fourth radiator 122 may jointly realize a sixth resonance and support a sixth wireless signal under the action of the second filter circuit 124. Furthermore, in the electronic device 10 or the antenna apparatus according to the embodiment of the present application, the two radiators can support at least two different radio frequency signals, so that not only can the space occupied by the radiators be saved, but also wireless signals of more frequency bands can be supported, and the antenna apparatus can be miniaturized.

Referring to fig. 13 again, the second antenna 120 may further include a third filter circuit 126 and a fourth filter circuit 127.

The third filter circuit 126 and the fourth filter circuit 127 may be provided on the circuit board 500, the small board 600 of the electronic device 10 or the antenna apparatus. One end of the third filter circuit 126 may be electrically connected between the fourth radiator 122 and the third feed 125, and one end of the third filter circuit 126 may also be electrically connected to any position of one side of the third feed 125 close to the third radiator 121 at the feeding end of the fourth radiator 122. The other end of the third filter circuit 126 may be electrically connected to the ground plane 200 to realize the grounding of the third filter circuit 126. Similarly, one end of the fourth filter circuit 127 may also be electrically connected between the fourth radiator 122 and the third feed 125, and one end of the fourth filter circuit 127 may also be electrically connected to any position of the third feed 125 at a side of the feeding end of the fourth radiator 122 close to the third radiator 121. The other end of the fourth filter circuit 127 may be electrically connected to the ground plane 200 to realize the grounding of the third filter circuit 126.

Referring to fig. 16 in conjunction with fig. 13, fig. 16 is a third current schematic diagram of the second antenna 120 shown in fig. 13. The second feed 123 may also provide a seventh driving signal I7, and when the second feed 123 feeds the seventh driving signal I7 to the third radiator 121, the seventh driving signal I7 may pass through the second filter circuit 124 and flow into the third radiator 121. At least a portion of the seventh excitation signal I7 (a portion of the seventh excitation signal I7 may flow on the third radiator 121 and back to ground through the third ground 1211) may be coupled from the third radiator 121 to the fourth radiator 122 through the second coupling gap 102 and flow in the fourth radiator 122. At the same time, the third filter circuit 126 may short circuit at least a portion of the seventh driving signal I7 and block at least a portion of the seventh driving signal I7 from flowing to the third feed 125. At this point, at least a portion of the seventh excitation signal I7 may be returned from the third filter circuit 126 to ground. At least a portion of the seventh excitation signal I7 may excite the third radiator 121 and at least a portion of the fourth radiator 122 may jointly form a seventh resonance and support a seventh wireless signal.

Referring to fig. 17 in conjunction with fig. 13, fig. 17 is a fourth current schematic diagram of the second antenna 120 shown in fig. 13. The second feed 123 may also provide a ninth driving signal I9, and when the second feed 123 feeds the ninth driving signal I9 to the third radiator 121, the ninth driving signal I9 may pass through the second filter circuit 124 and flow into the third radiator 121. At least a portion of the ninth excitation signal I9 (a portion of the ninth excitation signal I9 may flow on the third radiator 121 and back to ground through the third ground 1211) may be coupled from the third radiator 121 to the fourth radiator 122 through the second coupling gap 102 and flow in the fourth radiator 122. At the same time, the fourth filter circuit 127 may short circuit at least a portion of the ninth driving signal I9 and block at least a portion of the ninth driving signal I9 from flowing to the third feed 125. At this time, at least a portion of the ninth driving signal I9 may return to ground from the fourth filter circuit 127. The third radiator 121 and at least a portion of the fourth radiator 122 may jointly form a ninth resonance and support a ninth wireless signal.

It can be understood that, the short circuit of the third filter circuit 126 and the fourth filter circuit 127 to the seventh excitation signal I7 and the ninth excitation signal I9 may mean that the resistances of the third filter circuit 126 and the fourth filter circuit 127 are infinitesimally small in the frequency bands of the seventh excitation signal I7 and the ninth excitation signal I9, so that the seventh excitation signal I7 and the ninth excitation signal I9 are grounded.

It is understood that the antenna device may include only the third filter circuit 126, only the fourth filter circuit 127, and both the third filter circuit 126 and the fourth filter circuit 127.

Referring to fig. 18 in combination with fig. 13, fig. 18 is a fifth current schematic diagram of the second antenna 120 shown in fig. 13. The third feed 125 may also provide an eighth stimulus signal I8. When the third feed 125 feeds the eighth driving signal I8 to the fourth radiator 122, the eighth driving signal I8 may flow from the third feed 125 to the fourth radiator 122, and the eighth driving signal I8 may excite the fourth radiator 122 to generate an eighth resonance and support an eighth wireless signal. The eighth driving signal I8 does not couple the fourth radiator 122 with the third radiator 121, and the eighth driving signal I8 hardly flows in the third radiator 121.

It is understood that the second filter circuit 124, the third filter circuit 126 and the fourth filter circuit 127 may include, but are not limited to, a circuit formed by any series connection or any parallel connection of capacitors and inductors. This is not limited in the embodiments of the present application.

It is to be understood that one or more of the above-described fifth resonance, sixth resonance, seventh resonance, eighth resonance, and ninth resonance may be formed at the same time. For example, when the second feed 123 feeds an excitation signal to the third radiator 121 and the third feed 125 feeds an excitation signal to the fourth radiator 122, the third radiator 121 may realize a fifth resonance, the fourth radiator 122 may realize an eighth resonance, and the third radiator 121 and the fourth radiator 122 may jointly realize a sixth resonance, a seventh resonance, and a ninth resonance. Among them, the fifth wireless signal supported by the fifth resonance and the sixth wireless signal supported by the sixth resonance may return to the ground from the third ground 1211 of the third radiator 121, the eighth wireless signal supported by the eighth resonance may return to the ground from the fourth ground 1221 of the fourth radiator 122, the seventh wireless signal supported by the seventh resonance may return to the ground from the other end of the third filter circuit 126, and the ninth wireless signal supported by the ninth resonance may return to the ground from the other end of the fourth filter circuit 127.

Based on this, in the second antenna 120 of the embodiment of the application, when the second feed 123 feeds the excitation signal to the third radiator 121, under the action of the second filter circuit 124, the third filter circuit 126 and the fourth filter circuit 127, the third radiator 121 may support the fifth wireless signal, and the third radiator 121 and at least a part of the fourth radiator 122 may support the seventh wireless signal and the ninth wireless signal together. When the third feed 125 feeds an excitation signal to the fourth radiator 122, under the action of the second filter circuit 124, the third filter circuit 126 and the fourth filter circuit 127, the fourth radiator 122 may support an eighth wireless signal, and the fourth radiator 122 and at least a part of the third radiator 121 may support a sixth wireless signal together. Furthermore, in the second antenna 120 of the embodiment of the present application, the two radiators can support at least five radio frequency signals, which not only can save the space occupied by the radiators, but also can support wireless signals of more frequency bands, and can realize miniaturization of the second antenna 120.

As shown in fig. 13, the second antenna 120 may further include a second matching circuit 128 and a third matching circuit 129.

The second matching circuit 128 may be coupled between the second feed 123 and the third radiator 121, for example, in series between the second feed 123 and the second filter circuit 124. The second matching circuit 128 may match impedance when the second feed 123 provides the driving signal, so that the second feed 123 may provide the fifth driving signal I5, the seventh driving signal I7, and the ninth driving signal I9 to the third radiator 121.

The third matching circuit 129 may be coupled between the third feed 125 and the fourth radiator 122, for example in series between the third feed 125 and the third and

fourth filter circuits

126, 127. The second matching circuit 128 may match impedances at which the third feed 125 provides the stimulus signal such that the third feed 125 may provide the sixth stimulus signal I6 and the eighth stimulus signal I8 to the fourth radiator 122.

It is understood that the second matching circuit 128 and the third matching circuit 129 may include, but are not limited to, a circuit consisting of any series or any parallel connection of capacitors and inductors. This is not limited in the embodiments of the present application.

The second antenna 120 may support wireless signals of a plurality of different frequency bands. Referring to fig. 19 and 20 in combination with fig. 12, fig. 19 is a graph of an S-parameter of the second antenna 120 shown in fig. 12, and fig. 20 is a graph of a radiation performance of the second antenna 120 shown in fig. 12. In fig. 19, two curves S4 in the upper half are a reflection coefficient curve of the second antenna 120, and a curve S5 in the lower half is an isolation curve of the second antenna 120; in fig. 20, a curve S6 and a curve S7 are a radiation efficiency curve and a system efficiency curve, respectively, when the second feed 123 operates, and a curve S8 and a curve S9 are a radiation efficiency curve and a system efficiency curve, respectively, when the third feed 125 operates.

As can be seen from the curves S4 to S9, the fifth resonance generated by the third radiator 121 can support the fifth wireless signal of the GPS-L5 frequency band (1.15GHz to 1.5 GHz). The sixth resonance generated by the fourth radiator 122 and at least a portion of the third radiator 121 may support a sixth wireless signal in a Wi-Fi band of 2.4G (2.4GHz to 2.48GHz), or a sixth wireless signal in an N41 band (2.496GHz to 2.69GHz)/N41 band (2.496GHz to 2.69 GHz). The seventh resonance generated by the third radiator 121 and at least a portion of the fourth radiator 122 may support a seventh wireless signal of N78 band (3.3GHz to 3.8GHz)/B78 band (3.3GHz to 3.8 GHz). The eighth resonance generated by the fourth radiator 122 may support an eighth wireless signal of the GPS-L1(1.55GHz to 1.6GHz) band. The ninth resonance generated by the third radiator 121 and at least a portion of the fourth radiator 122 may support a ninth wireless signal of an N79 frequency band (4.4GHz to 5.0GHz)/B79 frequency band (4.4GHz to 5.0 GHz).

It can be understood from the curves S4 to S9 that the system efficiency averages of the second antenna 120 at the GPS-L1 frequency band, the 2.4G Wi-Fi frequency band, and the N41/B41 frequency band are about-3 dB, -4.1dB, and-3.2 dB, respectively; the system efficiency averages of the second antenna 120 under the GPS-L5 frequency band, the N78 frequency band/B78 frequency band, and the N79 frequency band/B79 frequency band are respectively about-9.8 dB, -3.3dB and-3.8 dB; the radiation performance of the second antenna 120 is extremely good.

It will be appreciated that the seventh resonance may also support an eighth wireless signal, for example, a signal supporting the N79 frequency band. Similarly, the eighth resonance may also support a seventh wireless signal, such as a signal supporting the N78 frequency band. This is not limited in the embodiments of the present application.

It is to be understood that the wireless signals supported by the fifth to ninth resonances are not limited to the above examples, and other wireless signals may be supported. This is not limited to the embodiments of the present application.

In the second antenna 120 of the embodiment of the application, the third filter circuit 126 and the fourth filter circuit 127 are equivalently short-circuited in the N78 and N79 frequency bands, respectively, and the seventh driving signal I7 and the ninth driving signal I9 are grounded from the second filter circuit 124 and the third filter circuit 126, so that when the second feed 123 feeds power, the second antenna 120 can work in the N78 and N79 frequency bands, and meanwhile, the second feed 123 and the third feed 125 can also generate good isolation, and the performance of the second antenna 120 is not affected. And the second filter circuit 124 is equivalent to an open circuit in the 2.4GWi-Fi and N41 frequency bands, and the sixth excitation signal I6 is grounded from the end of the third radiator 121, so that when the second feed 123 feeds power, the second antenna 120 can operate in the 2.4GWi-Fi and N41 frequency bands, and meanwhile, the second feed 123 and the third feed 125 can also generate good isolation.

In the second antenna 120 of the embodiment of the application, the third radiator 121 and the fourth radiator 122 are oppositely arranged to form the second coupling gap 102, so that the coverage of six frequency bands, namely, a GPS-L1 frequency band, a 2.4GWi-Fi frequency band, an N41/B41 frequency band, a GPS-L5 frequency band, an N78/B78 frequency band, and an N79/B79 frequency band, is realized in a smaller space. The antenna efficiency of the second antenna 120 in the GPS-L1 frequency band can be-3 dB, the performance is good, in addition, the second antenna 120 can also work in the GPS-L5 frequency band, the second antenna 120 can meet the high-precision positioning of the GPS-L1 and the GPS-L5 frequency band, and the positioning of a GPS system is well assisted. Meanwhile, the second antenna 120 can also work in 2.4Gwi-Fi, N41, N78 and N79 frequency bands, which is very suitable for the fifth generation mobile communication system.

The electronic device 10 or antenna arrangement may also include a third antenna 130, a fourth antenna 140, and a fifth antenna 150.

The radiator of the third antenna 130 may be disposed at the third frame 323. For example, the radiator of the third antenna 130 may be directly or indirectly connected to the third frame 323 and the projection of the radiator is located on the third frame 323; for another example, when the third frame 323 is made of a conductive material, the radiator of the third antenna 130 may be directly formed on the third frame 323 to implement multiplexing of the third frame 323. The radiator of the third antenna 130 may be disposed at an interval from the second radiator 112 of the first antenna 110 to reduce interference between the third antenna 130 and the first antenna 110.

At least most of the radiator of the fourth antenna 140 may be disposed on the second frame 322. As with the third antenna 130, the radiator of the fourth antenna 140 may be connected to or formed on the second bezel 322. The radiator of the fourth antenna 140 may be disposed opposite to the radiators of the first antenna 110 and the second antenna 120, and the radiator of the fourth antenna 140 may be disposed at an interval from the radiator of the third antenna 130, so that interference between the fourth antenna 140 and the first antenna 110, the second antenna 120, and the third antenna 130 is small.

The radiator of the fifth antenna 150 may be disposed on the fourth frame 324. As with the third antenna 130, the radiator of the fifth antenna 150 may be connected to or formed on the fourth frame 324. The radiator of the fifth antenna 150 may be disposed opposite to the radiator of the third antenna 130, and the radiator of the fifth antenna 150 may also be disposed at an interval from the radiators of the second antenna 120 and the fourth antenna 140, so that interference between the fifth antenna 150 and the first antenna 110, the second antenna 120, the third antenna 130 and the fourth antenna 140 is small.

It is understood that one or more of the first antenna 110, the second antenna 120, the third antenna 130, the fourth antenna 140, and the fifth antenna 150 may support wireless signals of the same frequency band, so that multiple antennas may implement a multiple-input multiple-output (MIMO) transmission system, and the electronic device 10 or the antenna apparatus may have a better transmission rate. For example, the first antenna 110, the third antenna 130, the fourth antenna 140, and the fifth antenna 150 may support signals of N28 band/B28 band.

For example, please refer to fig. 22 in conjunction with fig. 21, and fig. 22 is a graph of an S parameter of the electronic device 10 shown in fig. 21. The four curves S10 in the upper half of fig. 22 are the reflection coefficient curves of the first antenna 110, the third antenna 130, the fourth antenna 140, and the fifth antenna 150, respectively; the curves S11 on the lower half of fig. 22 are isolation curves of the first antenna 110, the third antenna 130, the fourth antenna 140, and the fifth antenna 150, respectively. As can be seen from fig. 22, the isolation among the first antenna 110, the third antenna 130, the fourth antenna 140, and the fifth antenna 150 is less than-17 dB, and the isolation among the plurality of antennas is good.

In the electronic device 10 or the antenna apparatus of the embodiment of the application, the four low-frequency antennas supporting the N28 frequency band are respectively located on four side edges of the electronic device 10 or the antenna apparatus, so that the four low-frequency antennas with longer radiation branches can be reasonably arranged, and the miniaturization design of the electronic device 10 or the antenna apparatus is realized.

Referring to fig. 23, fig. 23 is a fifth structural schematic diagram of an electronic device 10 according to an embodiment of the present disclosure. When at least most of the radiators of the second antenna 120 are also disposed on the first frame 321, an antenna structure combining the N28 frequency band and the MHB (medium-high frequency) frequency band (e.g., B3 frequency band, N41 frequency band), N78 frequency band, and N79 frequency band of the LTE can be implemented with a smaller top size. The electronic device 10 or the antenna apparatus may also implement an antenna structure integrating a GPS-L5 frequency band, a GPS-L5 frequency band, and four low-frequency antennas, and the antenna structure may meet the requirement of high-precision positioning of GPS dual-frequency bands, MIMO application requirement of 4 × 4N 28 frequency band, and the requirement of high-speed communication under the condition of long coverage distance.

Referring again to fig. 23, the electronic device 10 may further include a sixth antenna 160, a seventh antenna 170, and an eighth antenna 180.
