Abstract
Official abstract text for this publication.
A terminal is disclosed, wherein a metal back cover of the terminal includes a slot. The slot divides the metal back cover into two parts. One of the two parts is used as an antenna radiator. The antenna radiator includes a signal feed point, a first ground point, and at least one second ground point, so that an antenna of the terminal has four resonance points. The signal feed point is connected to a matching network, the first ground point is grounded by a switch device, and the second ground point is grounded. A distance between the signal feed point and the first ground point is less than a distance between the signal feed point and the second ground point, and none of the signal feed point, the first ground point, and the second ground point is located in an end of the slot.
First claim
Opening claim text (preview).
What is claimed is: 1. A terminal, wherein a metal back cover of the terminal includes a slot that divides the metal back cover into two parts, and one of the two parts is used as an antenna radiator of the terminal; wherein the antenna radiator includes a signal feed point, a first ground point, and at least one second ground point, so that an antenna of the terminal has four resonance points, wherein the signal feed point is connected to a matching network, the first ground point is grounded by a switch device, and the second ground point is grounded; and a distance between the signal feed point and the first ground point is less than a distance between the signal feed point and the second ground point, and none of the signal feed point, the first ground point, and the second ground point is located in a position, corresponding to an end of the slot, on the antenna radiator. 2. The terminal according to claim 1 , wherein the second ground point of the antenna radiator is grounded by an adjustable device. 3. The terminal according to claim 1 , wherein the second ground point of the antenna radiator is grounded by a fixed capacitor. 4. The terminal according to claim 1 , wherein the second ground point of the antenna radiator is grounded by a fixed inductor. 5. The terminal according to claim 1 , wherein the antenna radiator further includes a third ground point, the third ground point is grounded, and the third ground point is located in the position, corresponding to the end of the slot, on the antenna radiator. 6. The terminal according to claim 5 , wherein the third ground point of the antenna radiator is grounded by an adjustable device. 7. The terminal according to claim 5 wherein the third ground point of the antenna radiator is grounded by a fixed capacitor. 8. The terminal according to claim 5 wherein the third ground point of the antenna radiator is grounded by a fixed inductor. 9. The terminal according to claim 1 , wherein the first ground point of the antenna radiator is grounded by a capacitor and the switch device. 10. The terminal according to claim 1 , wherein the first ground point of the antenna radiator is grounded by an inductor and the switch device. 11. The terminal according to claim 1 , wherein the matching network connected to the signal feed point of the antenna radiator includes a variable capacitor.
