Millimeter wave refers to electromagnetic wave with frequency in the range of 30 GHz-300 GHz, and the corresponding wavelength range is 1 mm-10 mm. Since the wavelength of the millimeter wave is short, the transmission process is easily hindered, and the transmission performance of the second antenna 50 is effectively enhanced by arranging the plurality of millimeter wave antenna units at intervals.

When the middle frame is a metal middle frame, the first antenna 40 may be formed by grooving the metal middle frame, and the transmission of radio frequency signals in multiple frequency bands is realized by reasonably setting the length of the first antenna 40 and respectively grounding a plurality of grounding points on the first antenna 40.
The wearable electronic device 100 further includes: the antenna comprises at least three signal sources and at least three grounding points, wherein the three signal sources and the three grounding points are arranged on a circuit board 103, the first antenna 40, the second antenna 50 and the third antenna 60 are respectively connected with one corresponding signal source, the first antenna 40, the second antenna 50 and the third antenna 60 are respectively connected with one corresponding grounding point, each signal source is used for generating corresponding radio frequency signals, and the radio frequency signals of corresponding frequency bands are transmitted through the first antenna 40, the second antenna 50 and the third antenna 60.
As shown in fig. 1, when the second main body portion 20 and the first main body portion 10 are in a fully unfolded state, that is, when the angle between the first display screen 101 and the second display screen 201 is greater than a preset angle, the first antenna 40 and the second antenna 50 are respectively located at two sides of the wearable electronic device 100, where the first antenna 40 and the second antenna 50 are used for transmitting radio frequency signals, the third antenna 60 of the connection portion 70 is located between the first main body portion 10 and the second main body portion 20, and when a rear shell of the wearable electronic device 100 opposite to the display screen is made of a metal material, due to a shielding effect of the metal on the radio frequency signals, the third antenna 60 is not used for transmitting radio frequency signals, and the first antenna 40 and the second antenna 50 are used for transmitting radio frequency signals.
It can be understood that, when the rear case of the wearable electronic device 100 disposed opposite to the display screen is made of metal and the driving circuit is disposed under the display screen, the third antenna 60 is not used for transmitting the radio frequency signal in order not to affect the display performance of the display screen, and the first antenna 40 and the second antenna 50 are used for transmitting the radio frequency signal, because of the shielding effect of the metal on the radio frequency signal.
It will be appreciated that when the second main body 20 and the first main body 10 are in the fully unfolded state, the third antenna 60 may be used to transmit radio frequency signals when the rear case of the wearable electronic device 100 disposed opposite to the display screen is made of a non-metal material, in addition, considering the display performance of the display screen, the driving circuit of the display screen may not be disposed in the area where the third antenna 60 is disposed, the driving circuit is disposed in the area where the third antenna 60 is not disposed to control the display screen, and the transmission of radio frequency signals by the third antenna 60 is realized without affecting the display performance of the display screen, and at this time, the first antenna 40 and the second antenna 50 may also be used to transmit radio frequency signals.
It should be noted that, the first antenna 40, the second antenna 50, and the third antenna 60 are disposed at different positions of the wearable electronic device 100, so that good isolation can be formed between the antennas, and when the first antenna 40, the second antenna 50, and the third antenna 60 operate simultaneously, no interference occurs between radio frequency signals transmitted by the first antenna 40, the second antenna 50, and the third antenna 60, and transmission performance of the radio frequency signals can be improved.
With continued reference to fig. 2, fig. 2 is a second schematic structural diagram of the wearable electronic device according to the embodiment of the application.
As shown in fig. 2, when the first body 10 of the wearable electronic device 100 is in a fixed state, the second body 20 may rotate in the direction of the first display 101 through the rotating member of the connection 70, that is, the second body 20 rotates in the direction of P1 in the figure, and similarly, when the second body 20 is fixed, the first body 10 may also rotate along with the rotating member.
When the second body portion 20 rotates, an included angle is formed between the first body portion 10 and the second body portion 20, when the included angle is larger than a preset angle, the rear shells of the first body portion 10 and the second body portion 20 are further connected tightly, the third antenna 60 at the connection portion 70 has no antenna clearance area suitable for the operation of the third antenna 60, if the third antenna 60 is used for transmitting radio frequency signals, interference can be generated on the radio frequency signals transmitted by the third antenna 60, and therefore, the third antenna 60 is not used for transmitting radio frequency signals, and the first antenna 40 and the second antenna 50 are used for transmitting radio frequency signals, so that the antenna transmission performance is ensured.
When the angle of the included angle is smaller than the preset angle, the distance between the first antenna 40 and the second antenna 50 is relatively close, at this time, the wearable electronic device 100 is in the second state, if the first antenna 40 and the second antenna 50 are both used for transmitting radio frequency signals, the first antenna 40 and the second antenna 50 will interfere when transmitting radio frequency signals, and even if one of the first antenna 40 and the second antenna 50 is not connected to the signal source, electromagnetic coupling effect will also occur between the first antenna 40 and the second antenna 50, so as to interfere with the antenna for transmitting radio frequency signals for the user, therefore, at this time, neither the first antenna 40 nor the second antenna 50 is used for transmitting radio frequency signals, and the third antenna 60 is used for transmitting radio frequency signals, so as to ensure the transmission performance of the antenna.
With continued reference to fig. 3, fig. 3 is a third structural schematic diagram of the wearable electronic device according to the embodiment of the application.
As shown in fig. 3, since the first display screen 101 and the second display screen 201 are in a face-to-face folded state, that is, when the angle between the first display screen 101 and the second display screen 201 is not greater than the preset angle, the first display screen 101 and the second display screen 201 cannot be used for displaying contents, it is understood that on the second main body portion 20, the opposite side of the second display screen 201 is provided with a third display screen 203, where the third display screen 203 is used for displaying contents that the wearable electronic device 100 needs to display.
It is understood that the third display 203 may be formed of a rigid housing. The third display screen 203 may also include a liquid crystal display screen or an organic light emitting diode display screen (or the like type of display screen).
It will be appreciated that when the angle between the first display screen 101 and the second display screen 201 is not greater than the preset angle, the first body portion 10 and the second body portion 20 are in a completely folded state, that is, the first display screen 101 and the second display screen 201 are in a fitting state, the distance between the first antenna 40 and the second antenna 50 is very close, if both the first antenna 40 and the second antenna 50 are used for transmitting radio frequency signals, the first antenna 40 and the second antenna 50 will interfere when transmitting radio frequency signals, and even if one of the first antenna 40 and the second antenna 50 is not connected to a signal source, electromagnetic coupling effect will occur between the first antenna 40 and the second antenna 50, so that interference is caused to an antenna for transmitting radio frequency signals by a user, therefore, at this time, neither the first antenna 40 nor the second antenna 50 is used for transmitting radio frequency signals, and at this time, the third antenna 60 is used for transmitting radio frequency signals, so as to ensure the antenna transmission performance.
Referring to fig. 4, fig. 4 is a fourth structural schematic diagram of a wearable electronic device according to an embodiment of the application.
