It should be noted that the frame may be in a closed loop structure, that is, the frame may be closed to form a loop along the circumferential direction of the radiator, and in other embodiments, the frame may be in a non-closed loop structure and may extend along a portion of the edge of the radiator.
The feeding point 3 is connected between the circuit board 1 and a first radiator 22 on one side of the break 21, and the first ground point 4 is connected between the circuit board 1 and a second radiator 23 on the other side of the break 21.

It should be noted that the circuit board 1 is provided with a first line segment (not shown), and the first line segment is connected between the feeding point and the first ground point, so that the antenna assembly may form a complete antenna loop. Namely, the second radiator 23, the feeding point 3, the first grounding point 4, and the first wire section can construct a first antenna, and the wavelength of the constructed first antenna is smaller than one wavelength of radio frequency wave.
For example, the wavelength corresponding to the first antenna may be a quarter wavelength (corresponding to the latter 1/4 mode) of the radio frequency wave (first frequency band) or a half wavelength (corresponding to the latter 1/2 mode) of the radio frequency wave. It should be noted that, the specific wavelength of the first antenna may be adjusted by adjusting the position of the first ground point 4.
Alternatively, the feeding point 3 and the first grounding point 4 may be in the form of a spring, that is, the feeding point 3 may be a feeding spring, and the first grounding point 4 may be a first grounding spring.
Compared with the mode of receiving and transmitting radio frequency waves only through the feed point 3 in the prior art, the antenna assembly provided by the embodiment of the utility model is additionally provided with the first grounding point 4, the added first grounding point 4 can enable an independent loop to be formed between the second radiator 23 and the circuit board 1, and can construct a first antenna together with the feed point 3 and the second radiator 23 to form a new radiation mode (1/4 mode or 1/2 mode), so that the antenna assembly has better radiation capability, and the use requirements of high integration and limited space communication under limit stacking of the existing electronic equipment are met.

The circuit board 1 is provided with a second line segment (not shown) which is connected between the feed potential and the second ground point 5, by means of which the antenna assembly can also form a complete antenna loop. Namely the first radiator 22, the second ground point 5, the second line segment, and the feed point 3 constitute a second antenna, which is a LOOP antenna (LOOP antenna).
Alternatively, the second grounding point 5 may also be in the form of a spring plate.
The distance between the second ground point 5 and the resonance position on the loop antenna is smaller than the distance between the feed point 3 and said resonance position. For example, the two dashed arrows on the left side in fig. 1 may be regarded as the direction of conduction of the radio frequency waves of the second antenna. The intersection of the two dashed arrows may be considered a resonant position. The distance between the second ground point 5 and the resonance position in the left-right direction is smaller than the distance between the feeding point 3 and the resonance position.
Therefore, compared with the condition that radio frequency electric wave conduction is realized only through the feed point 3 in the prior art, the introduced second grounding point 5 changes the lower position of current, reduces the current overall path between the feed point and the resonance position on the circuit board 1, plays a role in inhibiting current, and compared with the original LOOP antenna (the antenna formed by the feed point 3, the first radiator 22 and the circuit board 1), the radiation of a new radiation mode (LOOP mode) can move towards high frequency, so that the antenna assembly has better radiation performance, and further meets the use requirement of arrangement of a limited space.
In some embodiments, the feeding point 3 is located between the first ground point 4 and the second ground point 5, and the break 21 and the first ground point 4 are located on the same side of the feeding point 3.

Therefore, the first antenna and the second antenna are relatively independent in structure, and the reliability and stability of the respective operation are ensured.
In some embodiments, the circuit board 1 is provided with a first supporting point 11 and a second supporting point 12, and the second grounding point 5 is disposed between the first supporting point 11 and the second supporting point 12. The first supporting point 11 and the second supporting point 12 can be regarded as supporting points with the function of supporting the circuit board 1, as shown in fig. 2, the first supporting point 11 can be arranged at the left side of the second grounding point 5, the second supporting point 12 can be arranged at the right side of the second grounding point 5, and the second grounding point 5 is arranged between the two supporting points to ensure the structural stability of the installation of the second grounding point 5.
In some embodiments, the connection between the feeding point 3 and the circuit board 1, and the connection between the first grounding point 4 and the circuit board 1 are all adjacent to the second supporting point 12. For example, as shown in fig. 2, the connection between the feeding point 3 and the circuit board 1 may be a first connection, the connection between the first grounding point 4 and the circuit board 1 may be a second connection, the first connection and the second connection may be integrated at one connection position, and the connection position may be adjacent to the second supporting point 12, and the structural stability of the connection may be ensured by means of the second supporting point 12.
The electronic device of the embodiment of the utility model is described below.
The electronic device according to the embodiment of the present utility model includes an antenna assembly, which may be the antenna assembly described in any of the above embodiments. The electronic device may be a mobile phone, which includes a middle frame 2, a circuit board 1 is disposed on the middle frame 2, and at least part of the middle frame 2 forms a radiator (a first radiator 22 and a second radiator 23) of the antenna assembly. In other embodiments, the electronic device may also be an electronic device with a communication function, such as a tablet computer, an electronic watch, or the like.
When the first grounding point 4 is not introduced, the antenna assembly of the electronic device is connected with the feeding point 3, and the current does not have a complete grounding path because the surrounding current does not have a grounding point, so that the structure does not have a 1/4 mode. After the first grounding point 4 is introduced, because the current around the feeding point 3 is stronger, the current can pass through the first grounding point 4 to the ground under the light sensing small plate according to the principle of nearby ground, and a current path from the antenna (the second radiator 23) to the feeding point 3 and then to the first grounding point 4 is constructed, so that a new 1/4 mode radiation mode is formed, and the mode mainly aims at the frequency range from 5GHz to 6 GHz.
When the first ground point 4 and the second ground point 5 are not introduced, the antenna radiation pattern of the existing electronic device is only a LOOP pattern, and the antenna efficiency is shown as a dotted line (a curve in fig. 4) in fig. 4. When the second ground point 5 is introduced, the second ground point 5 changes the position of the lower point of the current, suppressing the current between the first support point 11 and the second support point 12, so that the entire current path becomes short, and the formed new LOOP mode moves toward high frequency, at which time the antenna efficiency is shown by the broken line (B curve in fig. 4) in fig. 4.
When the first grounding point 4 is reintroduced, a 1/4 mode can be formed among the first grounding point 4, the feeding point 3 and the antenna, the corresponding antenna efficiency is shown as a solid line (C curve in fig. 4) in fig. 4, and the radiation capability of the antenna is further improved.
Specifically, as shown in fig. 4, after the antenna component of the electronic device of the present utility model is introduced into the second grounding point 5, by comparing the curve a and the curve B in fig. 4, the lowest point of the antenna efficiency in the frequency range of 5GHz to 6GHz is improved by about 4 dB. After further introduction of the first ground point 4, the overall antenna efficiency in the range of 5GHz to 6GHz is improved by 2dB to 3dB by comparing the B curve with the C curve in fig. 4.
The antenna component of the electronic equipment changes the position of a place under current, has higher antenna performance under a limited space, and meets the use requirements of high integration and communication under limit stacking of the existing electronic equipment.
While the above embodiments have been shown and described, it should be understood that the above embodiments are illustrative and not to be construed as limiting the utility model, and that variations, modifications, alternatives, and variations of the above embodiments may be made by those of ordinary skill in the art without departing from the scope of the utility model.
