Document Type and Number:
WIPO Patent Application WO/2018/068346
Kind Code:
A1
Abstract:
Disclosed is an antenna, comprising a slit-type antenna body, a feed branch, a first ground branch and a second ground branch. Taking the position of a feed point as a demarcation point, the slit-type antenna body is divided into a long branch and a short branch. The first ground branch comprises a switch and a grounded capacitive loading metal body, one end of the switch is connected to the capacitive loading metal body, and the other end of same is connected to a first ground pin at the long branch. The second ground branch comprises a plurality of branches connected in parallel; any one of the branches comprises an element; the plurality of branches are grounded through a plurality of switches; one of the plurality of switches corresponds to one branch; and one end of the element on any one of the branches is connected to a ground pin at the short branch, and the other end of same is connected to one switch corresponding to the branch. By means of a combination of turn-on and turn-off states of switches in the first ground branch and the second ground branch, a ground point and a ground element of an antenna can be changed so as to realize the overall coverage of a common communication frequency band by the antenna and solve the "death grip" problem of the antenna.
