it is noted that the positions of the first grounding point 104, the second grounding point 105 and the first feeding point 106 shown in fig. 1 are only schematic, and in practical applications, the distance between the first grounding point 104 and the first feeding point 106, and the distance between the first feeding point 106 and the second grounding point 105 need to be determined according to the electrical length corresponding to the frequency band supported by the electronic device.
Example two
The embodiment describes an electronic device, which is provided with a first shell and a second shell, where the first shell and the second shell form an accommodating space of the electronic device, the first shell may be a shell that accommodates a display unit of the electronic device, and the second shell may be a back shell of the electronic device; as shown in fig. 2a, the first housing comprises a first portion 201 and a second portion 202;
the first portion 201 and the second portion 202 both include a metal component (or all may be made of a metal material, which is not limited in this embodiment), and an insulating material 203 is further disposed between the first portion 201 and the second portion 202, so that the first portion 201 and the second portion 202 are in an electrically isolated state;

As an example, the first frequency band may be 2300Mhz to 2500Mhz (accordingly, the distance between the first feeding point 206 and the first ground point 204 corresponds to an electrical length resonant to the first frequency band), and the second frequency band may be 790Mhz to 960Mhz (accordingly, the distance between the first feeding point 206 and the second ground point 205 corresponds to an electrical length resonant to the second frequency band), even though the second portion 202 of the second housing is formed with two antenna elements; the distance from the first feeding point 206 to the first end 208 of the first radiator 207 corresponds to the electrical length of the third frequency band (2500Mhz to 2700Mhz), that is, the first radiator 207 forms an antenna unit resonant to the third frequency band, which is equivalent to extending the frequency band supported by the second portion 202; thus, three antenna units are formed by the second part 202 of the shell and the first radiator 207, and the three antenna units resonate in different frequency bands, so that the coverage of multiple frequency bands required to be supported by the 4G terminal is realized, and the problem that the multiple frequency bands are difficult to cover when all metal shells are adopted by electronic equipment in the related art is solved; moreover, the second portion 202 of the first housing may be disposed at an end of the electronic device far from the earpiece portion, that is, an end surface of the bottom of the electronic device holder, so as to avoid the performance of the first radiator 207 being affected when the user holds the electronic device, and avoid the performance of the first radiator 207 being affected by the head of the user when the second portion 202 is disposed close to the earpiece portion.
As another example, the first frequency band may be 2300Mhz to 2700Mhz (accordingly, the distance between the first feeding point 206 and the first ground point 204 corresponds to an electrical length resonant to the first frequency band), and the second frequency band may be 790Mhz to 960Mhz (accordingly, the distance between the first feeding point 206 and the second ground point 205 corresponds to an electrical length resonant to the second frequency band), even though the second portion 202 of the second housing is formed with two antenna elements; the distance from the first feeding point 206 to the first end 208 of the first radiator 207 corresponds to the electrical length of a third frequency band (same as the first frequency band, 2300Mhz to 2700Mhz), that is, the first radiator 207 forms an antenna unit resonant to the first frequency band, which is equivalent to enhancing the performance of the second portion 202 in the first frequency band; thus, three antenna units are formed by the second part 202 of the shell and the first radiator 207, so that the coverage of multiple frequency bands required to be supported by the 4G terminal is realized, and the problem that the multiple frequency bands are difficult to cover when all-metal shells are adopted by electronic equipment in the related art is solved; moreover, the second portion 202 of the first housing may be disposed at an end of the electronic device far from the earpiece portion, that is, an end surface of the bottom of the electronic device holder, so as to avoid the performance of the first radiator 207 being affected when the user holds the electronic device, and avoid the performance of the first radiator 207 being affected by the head of the user when the second portion 202 is disposed close to the earpiece portion.
It should be noted that the positions of the first grounding point 204, the second grounding point 205 and the first feeding point 206, and the length from the first feeding point 206 to the first end of the first radiator 207 shown in fig. 2a and 2b are only schematic, and in practical applications, the distance between the first grounding point 204 and the first feeding point 206, the distance between the first feeding point 206 and the second grounding point 205, and the length from the first feeding point 206 to the first end 208 of the first radiator 207 need to be determined according to the electrical length corresponding to the frequency band supported by the electronic device.

As an example, the first frequency band may be 2300Mhz to 2500Mhz (in this case, the distance between the first feeding point 506 and the first ground point 504 corresponds to an electrical length resonant to the first frequency band), and the second frequency band may be 790Mhz to 960Mhz (in this case, the distance between the first feeding point 506 and the second ground point 505 corresponds to an electrical length resonant to the second frequency band), even though the second portion 502 of the second housing is formed with two antenna units; the distance from the first feeding point 506 to the first end 511 of the first radiator 507 corresponds to the electrical length of the third frequency band (2500 Mhz-2700 Mhz), that is, the first radiator 507 forms an antenna unit resonant to the third frequency band; the distance from the third feeding point 510 to the first end 512 of the second radiator 509 corresponds to the electrical length of the antenna resonating at the fourth frequency band (1710Mhz to 2170Mhz), that is, the second radiator 509 forms an antenna unit resonating at the fourth frequency band; thus, four antenna units are formed by the second part 502 of the shell, the first radiator 507 and the second radiator 509, and the four antenna units resonate in different frequency bands, so that the coverage of multiple frequency bands required to be supported by the 4G terminal is realized, and the problem that the multiple frequency bands are difficult to cover when the electronic equipment adopts an all-metal shell in the related art is solved;

in the above example, the second portion 502 of the first casing may be disposed at an end of the electronic device far from the earpiece portion, that is, an end surface of the bottom of the electronic device holding portion, so as to avoid the performance of the first radiator 507 being affected when the user holds the electronic device, and avoid the performance of the first radiator 507 being affected by the head of the user when the second portion 502 is disposed close to the earpiece portion.
It should be noted that the position of the first grounding point 504, the distance from the second grounding point 505 to the first feeding point 506, the distance from the first feeding point 506 to the first end of the first radiator 507, and the distance from the third feeding point 510 to the first end 512 of the second radiator 509 shown in fig. 5a and 5b are merely schematic, and in practical applications, the position of the first grounding point 504, the distance from the first grounding point 504 to the first feeding point 506, the distance between the first feeding point 506 and the second grounding point 505, the distance from the first feeding point 506 to the first end 511 of the first radiator 507, and the distance from the third feeding point 510 to the first end 512 of the second radiator 509 need to be determined according to the electrical length corresponding to the frequency band supported by the electronic device.
