7. The electronic device of claim 6, wherein the length of the antenna radiator is greater than a target value; the target value is the product of the antenna wavelength corresponding to the antenna radiator and a preset value.

8. The electronic device of claim 5, wherein the conductive body is a capacitor, wherein the antenna radiator includes a fifth boss and a sixth boss, wherein the fifth boss is disposed between the first feed port and the second feed port, wherein the sixth boss is disposed between the second feed port and the inductor, and wherein a length between the fifth boss and the first feed port is the same as a length between the sixth boss and the first end of the antenna radiator.

9. The electronic device of claim 8, wherein the length of the antenna radiator is less than a target value; the target value is the product of the antenna wavelength corresponding to the antenna radiator and a preset value.

10. The electronic device of any of claims 5-9, wherein the slot includes a first sidewall and a second sidewall that are perpendicular to each other, and wherein the first sidewall is disposed parallel to the antenna radiator.
