Title:
ANTENNA DEVICE AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2019/071848
Kind Code:
A1
Abstract:
An antenna device comprises a feed branch, a first grounding branch, and a radiating body. The radiating body comprises a first radiating section and a second radiating section. There is a gap between the first radiating section and the second radiating section. The end of the first radiating section distant from the second radiating section is grounded. The feed branch comprises a feed end and a first connecting end. A first capacitor is connected in series between the feed end and the first connecting end. The first connecting end is located at an intersection between the feed branch and the second radiating section. The distance between the first connecting end and the gap is within a preset range, so that the first radiating section forms a parasitic antenna radiating signals in a first band. The first grounding branch comprises a first grounding end and a second connecting end. The second connecting end is located at an intersection between the first grounding branch and the second radiating section. A matching circuit is connected in series between the second connecting end and the first grounding end. The current fed from the feed end reaches the first grounding through the matching circuit to radiate signals in a second band. The present application also provides a mobile terminal. The present application can implement coverage of frequency ranges of different bands.
