when the cavity antenna 12 transmits and receives a radio signal, the current direction 133A of the intermediate connection line 133 is different from the current direction 12A of the cavity antenna 12.

In an embodiment of the disclosure, an electronic device includes a motherboard. The main board can be a printed circuit board (Printed Circuit Board, PCB), a flexible circuit board (Flexible Printed Circuit, FPC) or a soft and hard combined board.

Taking electronic equipment as an example of a mobile phone, a main board in the mobile phone is responsible for controlling the operation of the whole mobile phone, and the main board is integrated with a processor, a baseband chip, a Radio Frequency (RF) chip, a storage chip, a battery management chip, a display screen interface and other components; the radio frequency chip is a chip capable of converting radio frequency signals and digital signals and comprises an RF transceiver, a power amplifier (PowerAmplifier, PA), a low noise amplifier (LowNoiseAmplifier, LNA), a filter, a radio frequency switch, an antenna tuning switch and the like.

In the embodiment of the disclosure, the electronic device further comprises a cavity antenna, and the electronic device can send and receive wireless signals through the cavity antenna. Wherein the wireless signal is one of electromagnetic waves; the cavity antenna includes: dipole cavity antennas, monopole cavity antennas, spiral cavity antennas, slot cavity antennas, etc., the type and shape of the cavity antennas are not limited in embodiments of the present disclosure.

It should be noted that the cavity antenna may be a box made of all-conductive materials; or the structure is enclosed by a middle frame and a plurality of conductive structural members; and can also be enclosed by a middle frame and a conductive flexible structural member.

Here, since the cavity antenna is far away from the main board, it is required to be connected to the main board through a transmission line. In an embodiment of the disclosure, the electronic device further includes a transmission line including a first connection end connected to the motherboard, a second connection end connected to the cavity antenna, and an intermediate connection line connected between the first connection end and the second connection end. Wherein, the transmission line comprises coaxial lines, multiple leads, strip lines, microstrip lines and the like; the transmission line can be in any shape, and the corresponding first connecting end, second connecting end and intermediate connecting line can be in any shape. Exemplary shapes include dog-leg, straight, curved, etc.; the lengths of the first connection end and the second connection end are not limited in the embodiments of the present disclosure. Taking a transmission line as an example of a coaxial line, the coaxial line can be connected with a radio frequency chip on the main board, and the electronic equipment is connected with the cavity antenna through the coaxial line and acts together with the radio frequency chip to receive and transmit wireless signals.

In the embodiment of the disclosure, under the condition that the cavity antenna transmits and receives wireless signals, the current direction of the intermediate connecting wire is different from the current direction of the cavity antenna, namely, an included angle is formed between the current direction of the intermediate connecting wire and the current direction of the cavity antenna, and the included angle is between 0 and 180 degrees.

Here, the current of the transmission line is distributed along the axis direction of the transmission line, the wireless signal is transmitted in the form of a traveling wave sine wave on the transmission line, and the electric field of the transmission line is also distributed along the axis direction of the transmission line, and the polarization direction of the transmission line is the electric field direction of the transmission line. It should be noted that, on the basis of satisfying that the current direction of the intermediate connection line is different from the current direction of the cavity antenna, the position between the intermediate connection line and the cavity antenna is not limited in this disclosure, for example, the intermediate connection line may be parallel to the cavity antenna or may be perpendicular to the cavity antenna.

When the current direction of the intermediate connecting wire is the same as the current direction of the cavity antenna, the coupling between the intermediate connecting wire and the cavity antenna is large, and correspondingly, the influence of the whole transmission line on the cavity antenna is large; when the current direction of the intermediate connecting wire is different from the current direction of the cavity antenna, namely, an included angle between the current direction of the intermediate connecting wire and the current direction of the cavity antenna is between 0 and 90 degrees or between 90 and 180 degrees, but the coupling between the intermediate connecting wire and the cavity antenna is reduced when the angle does not comprise 0 and 90 degrees, and correspondingly, the influence of the whole transmission line on the cavity antenna is reduced; when the current direction of the intermediate connecting wire is perpendicular to the current direction of the cavity antenna, the intermediate connecting wire and the cavity antenna are not coupled, and correspondingly, the influence of the whole transmission line on the cavity antenna can be reduced to the greatest extent.

Illustratively, in the related art, in order to reduce the influence of the coaxial line on the cavity antenna, it is generally adopted that the coaxial line is perpendicular to the side of the cavity antenna so that the coaxial line is far from the cavity antenna. However, the current of the cavity antenna is the same as the current of the coaxial line due to the fact that the coaxial line is perpendicular to the cavity antenna, so that signals transmitted by the coaxial line and signals transmitted by the cavity antenna are overlapped, deep fading of the amplitude of the signals occurs, and the efficiency of receiving and transmitting wireless signals by the electronic equipment is low.

In the embodiment of the disclosure, under the condition that the cavity antenna transmits and receives wireless signals, the current direction of the intermediate connecting wire is different from the current direction of the cavity antenna. That is, the current direction of the intermediate connecting wire is different from the polarization direction of the cavity antenna, so that the interference of the intermediate connecting wire to the cavity antenna when the cavity antenna transmits and receives wireless signals can be reduced, the influence of the whole transmission line on the cavity antenna is further reduced, and the transmitting and receiving efficiency of the cavity antenna is improved.

In some embodiments, the current direction of the intermediate connection line is perpendicular to the current direction of the cavity antenna.

It should be noted that, on the basis of satisfying that the current direction of the intermediate connection line is perpendicular to the current direction of the cavity antenna, the present disclosure is not limited in the position between the intermediate connection line and the cavity antenna.

Illustratively, the cavity antenna is defined by a center frame and an antenna radiating plate, the antenna radiating plate including a first side and a second side adjacent the first side, the first side and the second side may define an antenna radiating plane; the current direction of the middle connecting line can be perpendicular to the current direction of the second side edge, can be perpendicular to the current direction of the diagonal line of the antenna radiation surface, and can be perpendicular to the current direction of the first side edge.

Fig. 2 is a schematic diagram of a return loss curve and an efficiency curve of an electronic device according to an exemplary embodiment, where, as shown in fig. 2, a vertical axis represents a return loss value and an efficiency value of a wireless signal, and a horizontal axis represents a frequency of the wireless signal. The return loss value and the efficiency value are expressed by gains, and the unit is dB; the return loss value is the ratio of the incident power to the reflected power of the wireless signal, and the efficiency value is the ratio of the radiation power to the incident power of the wireless signal.

In fig. 2, a return loss curve 1 is a return loss curve of a wireless signal corresponding to a case where a current direction of an intermediate connection line is perpendicular to a current direction of a cavity antenna, an efficiency curve 1 is an efficiency curve of a wireless signal corresponding to a case where a current direction of an intermediate connection line is perpendicular to a current direction of a cavity antenna, a return loss curve 2 is a return loss curve of a wireless signal corresponding to a case where a current direction of an intermediate connection line is identical to a current direction of a cavity antenna, and an efficiency curve 2 is an efficiency curve of a wireless signal corresponding to a case where a current direction of an intermediate connection line is identical to a current direction of a cavity antenna.

As shown in fig. 2, the return loss curve 2 and the efficiency curve 2 both have pits, which indicate that the wireless signal is attenuated during transmission; and the return loss curve 1 and the efficiency curve 1 are smoother, which indicates that the loss of the wireless signal is less. Based on the above, the influence of the whole transmission line on the cavity antenna when the current direction of the intermediate connection line is perpendicular to the current direction of the cavity antenna is smaller than the influence of the whole transmission line on the cavity antenna when the current direction of the intermediate connection line is the same as the current direction of the cavity antenna.

In the embodiment of the disclosure, the current direction of the intermediate connecting wire is perpendicular to the current direction of the cavity antenna, so that the current direction of the intermediate connecting wire is perpendicular to the polarization direction of the cavity antenna, and the electric field intensity vector of the intermediate connecting wire is independent of the electric field intensity vector of the cavity antenna, so that the interference of the transmission line to the cavity antenna can be reduced to the greatest extent, and the receiving and transmitting efficiency of the cavity antenna is further improved.

In some embodiments, as shown in fig. 3, the electronic device 100 further comprises:

a middle frame 14;

the antenna radiation plate 15 is positioned on the middle frame 14 and encloses the cavity antenna 12 with the middle frame 14;

the intermediate connection line 133 is located on the middle frame 14 and is parallel to the antenna radiation plate 15.

In an embodiment of the disclosure, the electronic device further includes a middle frame; the antenna radiation plate is positioned on the middle frame and forms a cavity antenna with the middle frame. Because the middle frame is a stable structural member, the stability of fixing the antenna radiation plate can be improved. Wherein, the antenna radiation plate material is conductive material. By way of example, it may be a conductive glass; but also metals such as silver, copper, aluminum, alloys, etc.

It should be noted that, the size of the antenna radiation plate is inversely proportional to the frequency of the wireless signal, i.e. the higher the frequency of the wireless signal is, the smaller the corresponding antenna radiation plate size is; also, there is a gap between the antenna radiating plate and the center frame to form an effective cavity space, and the gap may be greater than 0.7mm, for example.

In the embodiment of the disclosure, the middle connecting wire is also positioned on the middle frame and parallel to the antenna radiation plate, and the occupation of the space of the electronic equipment can be reduced relative to vertical placement. It is understood that the antenna radiation plate has a thickness, and the antenna radiation plate includes a first face facing the center frame, a second face opposite to the first face, and a plurality of third faces disposed adjacent to the second face; correspondingly, the intermediate connecting line may be parallel to the second face or may be parallel to one of the third faces.

In the embodiment of the disclosure, the antenna radiation plate and the intermediate connecting wire in the electronic device are both positioned on the middle frame, and the middle frame is an existing and stable structural member, so that the stability of fixing the antenna radiation plate and the intermediate connecting wire can be improved without additionally introducing other structural members. In addition, the middle connecting line is parallel to the antenna radiation plate, so that occupation of space of the electronic equipment can be reduced, and the space utilization rate of the electronic equipment is improved.

In some embodiments, as shown in fig. 3, the cavity antenna 12 is formed with an opening 152 at the first side 151 of the antenna radiation plate 15, the opening 152 being for the wireless signal output;

the antenna radiation plate 15 further includes a second side 153 disposed adjacent to the first side 151;

the middle connecting line 133 is located at the second side 153 and is parallel to the second side 153.

In an embodiment of the disclosure, the cavity antenna is formed with an opening at a first side of the antenna radiation plate, the opening being for wireless signal output. Electromagnetic waves in the cavity of the cavity antenna can radiate to the external space through the opening, or the electromagnetic waves in the external space can enter the cavity of the cavity antenna through the opening, so that the cavity antenna can transmit and receive wireless signals.

Fig. 4 is a diagram illustrating a current distribution diagram of the antenna radiation plate 15 and the transmission line 13 according to an exemplary embodiment, and as shown in fig. 4, the current direction of the first side 151 is along the extending direction of the first side 151, the current direction of the second side 153 is perpendicular to the intermediate connection line 133, some of the currents in the antenna radiation plate 15 are perpendicular to the intermediate connection line 133, and some of the currents are horizontal to the intermediate connection line 133. If the middle transmission line is parallel to the diagonal line of the antenna radiation plate, although the current direction of the middle transmission line is perpendicular to the current direction of a part of the antenna radiation plate, the current direction of the middle transmission line is not perpendicular to the current direction of the antenna radiation plate due to uneven current distribution in the antenna radiation plate, so that mutual interference exists between the middle connection line and the electromagnetic wave of the cavity antenna.

In an embodiment of the disclosure, the antenna radiation plate further includes a second side disposed adjacent to the first side; the middle connecting line is positioned at the second side edge and is parallel to the second side edge.

Therefore, the part closest to the middle connecting wire in the antenna radiation plate is the second side edge, the middle connecting wire is little interfered by other areas of the antenna radiation plate except the second side edge, and the current direction of the middle connecting wire is perpendicular to the current direction of the second side edge, so that the interference of the middle connecting wire to the cavity antenna can be reduced to the greatest extent, and the receiving and transmitting efficiency of the cavity antenna is further improved.

In some embodiments, as shown in fig. 3, the main board 11 is located on the middle frame 14;

the middle connecting line 133 is located between the main board 11 and the second side 153;

the second side is a side of the antenna radiation plate, which is close to the main board.

In this embodiment of the disclosure, the intermediate connection line is located between the main board and the second side, and the second side is a side close to the main board in the antenna radiation board. Compared with other side surfaces, far away from the main board, of the main board and the antenna radiation plate, the main board is short in middle connecting line required by connection with the second side surface, and the length of the middle connecting line is reduced, so that the whole length of the transmission line is reduced, and the loss of wireless signals and the occupation of the internal space of the electronic equipment can be reduced simultaneously.

In some embodiments, the length of the intermediate connecting line is less than or equal to the length of the second side edge.

For example, when the length of the second side edge is 23 millimeters (mm), the length of the intermediate connecting line may be less than or equal to 23mm. The length of the intermediate connecting wire is reduced, so that the whole length of the transmission line is reduced, and the loss of wireless signals and the occupation of the internal space of the electronic equipment can be reduced at the same time.

In some embodiments, the distance between the intermediate connecting line and the second side edge is in the range of 1 millimeter and 4 millimeters.

In an embodiment of the present disclosure, a distance between the intermediate connecting line and the second side edge is greater than or equal to 1 millimeter and less than or equal to 4 millimeters. Illustratively, the distance between the intermediate connecting line and the second side edge may be 1.5mm.

In some embodiments, the middle frame is formed with a fixing groove;

the middle connecting wire is arranged in the fixing groove.

In the embodiment of the disclosure, the middle frame is formed with a fixing groove, and the middle connecting wire is installed in the fixing groove. In some embodiments, the fixing groove may have an elastic inner wall that presses the intermediate connection line, and the intermediate connection line presses the elastic inner wall of the fixing groove, so that the inner wall of the fixing groove is elastically deformed, thereby clamping the intermediate connection line; in other embodiments, a wire clip may be further disposed in the fixing groove to clamp the intermediate connection wire.

In the embodiment of the disclosure, on one hand, the fixing groove can fix the intermediate connecting wire, so as to reduce occurrence of displacement of the intermediate connecting wire, and if the displacement of the intermediate connecting wire is serious, for example, the intermediate connecting wire is displaced to a screw or other parts with high strength or stress, the intermediate connecting wire may be extruded to fracture; on the other hand, the fixing groove is formed in the middle frame, so that no extra requirement is required for the space of the electronic equipment, and the occupation of the space of the electronic equipment can be reduced.

In other embodiments, the middle frame may be protruded toward the antenna radiation plate to form a clip; the intermediate connecting wire is arranged in the wire clamp. Therefore, the fixing mode of the intermediate connecting wire can be more flexible.
