Title:
ANTENNA APPARATUS AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2018/068344
Kind Code:
A1
Abstract:
An antenna apparatus, comprising: a band-stop filter (105), one end of which is electrically connected to a feed branch (103) and the other end of which is electrically connected to a ground branch (104); a first antenna branch (101) for forming, with the feed branch (103), a first sub-antenna for generating an electrical signal with a first resonance frequency; and a second antenna branch (102) for forming, with the feed branch (103), a second sub-antenna for generating an electrical signal with a second resonance frequency, wherein the second antenna branch (102), the feed branch (103) and the ground branch (104) form a loop antenna for generating an electrical signal of a third resonance frequency, and the electrical length of the loop antenna is 1/4 of the wavelength of the electrical signal of the third resonance frequency; and the band-stop filter (105) may filter electrical signals in a pre-set stop-band resonance frequency range. Also provided is a mobile terminal. An operating frequency band of an antenna can be expanded to a wider range without using a switching device, and by adding a ground branch (104) to separate electrical signals of different frequency bands, the cost of a UE is reduced; moreover, the parasitic effect brought about by the switching device can also be avoided to improve the performance of the antenna.
