Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
Example one

Specifically, the antenna couples the received high-frequency current signal to the rotating shaft, so that the rotating shaft radiates a wireless signal of at least one frequency band due to the high-frequency current signal generated by the coupling; the rotating shaft converts the received electromagnetic waves into high-frequency current signals, and couples the high-frequency current signals to the antenna.
Here, the electronic device may be a tablet computer or a notebook computer; when the electronic device is a tablet computer, the connecting piece is equivalent to a rotating shaft part of the support.
In an embodiment, when the electronic device is a notebook computer, the body includes a first body and a second body, and the first body and the second body change relative positions thereof through the connecting member.
Here, the antenna includes at least the following antenna types: wireless Local Area Network (WLAN) antennas, conventional small wireless built-in antennas, global positioning system antennas, and bluetooth antennas.
Therefore, the embodiment of the invention adopts a miniaturization design technology to design the antenna into the space at the rotating shaft of the electronic equipment, and the rotating shaft cover is shared as the antenna cover to realize the hidden antenna design, thereby meeting the requirements of a wireless communication system.
Example two
Fig. 2 is a schematic diagram of a second composition of an electronic device according to an embodiment of the present invention, as shown in fig. 2, the notebook computer 20 includes a main body 21 and a connecting member 22, the connecting member 22 includes a rotating shaft 221, the electronic device further includes an antenna 222 disposed in a clearance area formed by the connecting member 22, the antenna 222 resonates in at least one frequency band and is coupled to the rotating shaft 221, so that the rotating shaft 221 resonates in at least one frequency band.
Specifically, the antenna 222 couples the received high-frequency current signal to the rotating shaft 221, so that the rotating shaft 221 radiates a wireless signal of at least one frequency band due to the high-frequency current signal generated by the coupling; the rotating shaft 221 converts the received electromagnetic waves into high-frequency current signals, and couples the high-frequency current signals to the antenna 222.
In one embodiment, the connecting member has a slot, the rotating shaft is exposed from the slot of the connecting member, and a radiator formed by the rotating shaft and the antenna generates resonance in the first frequency band due to the size of the slot; the size of the slot hole corresponds to the electrical length of a radiator formed by the antenna and the rotating shaft.
Here, the antenna resonates in a first frequency band and resonates in a second frequency band, and the second frequency band is a frequency multiplication band of the first frequency band.
Specifically, as shown in fig. 3, the antenna is used as an excitation component to couple energy to the rotating shaft by means of capacitive coupling at high frequency, so that the rotating shaft is excited to become an antenna radiator. Because a slot with certain width and length is formed between the rotating shaft and the surrounding shell, the length and the width of the slot (the length of the rotating shaft) are adjusted to enable the antenna to reach the length of radiation in a 2.4GHz frequency band, at the moment, the electrical length is close to 1/4 wavelengths, and when the slot is excited, resonance can be generated in the 2.4GHz frequency band; meanwhile, frequency multiplication resonance can be generated near the 5GHz frequency band, and the dual-frequency requirement of covering the WLAN communication system is met.
On a multimode notebook computer in the form of Yoga and the like, considering the change of the conventional antenna design on the antenna environment when the antenna is applied in multimode, the antenna performance is influenced when different use modes are switched, and even the antenna performance in some application modes is possibly poor, so that the user experience is influenced; in addition, when the conventional antenna is designed, the antenna is arranged at the periphery of a display screen in the shell or at the periphery of components such as a main board battery and the like, and because the antenna radiates energy, no matter the antenna is arranged, the shell near the antenna is made of non-metallic materials, so that electromagnetic signals are prevented from being shielded; for the model of the metal casing, the antenna design becomes a bottleneck, and a non-metal window area (antenna window) with a certain area needs to be reserved on the antenna area on the casing, which causes design difficulty, cost increase and limitation on process and material. In order to solve the above problems, the embodiments of the present invention adopt a miniaturized design technology to design an antenna in a space at a left rotating shaft and a right rotating shaft which can be turned over only 360 degrees based on the overall layout of a notebook computer with a Yoga multi-mode type, and share a rotating shaft cover as an antenna cover to realize a hidden antenna design, so as to realize a dual-frequency dual-antenna design, thereby meeting the requirements of a WLAN wireless communication system.

Specifically, as shown in fig. 4, in the embodiment of the present invention, the tuning of the resonant frequency can be achieved by adjusting the length of the rotating shaft or the grounding position to change the size of the slotted hole formed between the rotating shaft and the ground plane, i.e., the metal housing 41, where the length of the slotted hole, i.e., the formed current path, increases to lower the resonant frequency, and vice versa to raise the resonant frequency; alternatively, because the antenna and the coupling capacitor are also part of the integral slot aperture design, tuning of the resonant frequency is achieved by adjusting the amount of capacitive coupling between the antenna and the shaft, i.e., adjusting the size, shape and distance to the shaft, as well as the size of the antenna itself. Further, in order to meet the requirement of wide band coverage of the 5GHz band, the grounding parasitic unit 42 is added between the rotating shaft and the antenna, and the length, the shape and the distance between the rotating shaft and the antenna are adjusted to enable the rotating shaft to generate a resonance on the 5GHz band, so that the resonance is combined with the high-frequency resonance generated by the slotted hole to realize the wide band resonance.
