The millimeter wave refers to an electromagnetic wave having a frequency in a range of 30GHz to 300GHz, and the corresponding wavelength range is 1mm to 10 mm. Because the wavelength of millimeter waves is short, the transmission process is easy to be blocked, and the transmission performance of the second antenna is effectively enhanced by arranging a plurality of millimeter wave antenna units at intervals. In the embodiment of the application, the second antenna is used for transmitting signals in N78(3.3 GHz-3.6 GHz) and N79(4.8 GHz-5 GHz) frequency ranges.

The millimeter wave antenna unit may be a patch antenna, which is attached to the inner surface or the outer surface of the wearing portion 90, and the plurality of patch antennas are arranged in an array. The millimeter wave antenna units may also be slot antennas, a plurality of slots are formed on the surface of the wearing portion 90, the slot antennas are arranged in an array, and the distance between two adjacent millimeter wave antenna units may be greater than or equal to 1/2 wavelengths, so as to reduce performance degradation caused by mutual coupling.

In some embodiments, the surface of the wearing portion 90 may be provided with a plurality of through grooves, and the millimeter wave antenna units may be directly embedded in the through grooves due to the short wavelength of the millimeter wave, so that the physical size of the millimeter wave antenna units is small.

It can be understood that the array arrangement may be a matrix array or a linear array, for example, a plurality of millimeter wave antenna units may be disposed at intervals along the extending direction of the wearing portion 90 to form a linear array, the extending direction of the wearing portion 90 is the length direction of the wearing portion 90, when a user holds the hand, for example, the user blocks a part of the millimeter wave antenna units, the second antenna may transmit signals through other millimeter wave antenna units that are not blocked, thereby reducing interference to the second antenna when the user holds the hand.

In some embodiments, the array arrangement may also be an arrangement forming a specific pattern, such as a circle, a square, an ellipse, a triangle, or any other arbitrary shape, which is not limited herein.

It is understood that the wearable electronic device 100 may further include a second signal source, which may be disposed on the circuit board 40, and which is electrically connected to the second antenna, and which may be used to generate 5G millimeter wave signals.

The wearable electronic device provided by the embodiment of the application is described in detail above. The principles and implementations of the present application are described herein using specific examples, which are presented only to aid in understanding the present application. Meanwhile, for those skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
