Abstract

The invention discloses an antenna device and an electronic device. The above antenna device comprises a high-frequency antenna, a low-frequency antenna and a combiner, wherein one input end of the combiner is coupled with the high-frequency antenna, the other input end of the combiner is coupled with the low-frequency antenna separately through a first passage and a second passage, an output end of the combiner is used for being in feeding coupling with the antennas, the first passage is formed by connecting the other input end of the combiner, a first reactor device, a first switch and a first contact point of the low-frequency antenna in series, and the second passage is formed by connecting the other input end of the combiner and a second contact point of the low-frequency antenna in series. With the technical scheme provided by the invention, wider frequency band coverage can be achieved.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to an antenna device and an electronic terminal. Background technique [0002] In order to rationally use spectrum resources and ensure that various industries and services will not interfere with each other when using spectrum resources, the International Telecommunication Union Radio Committee (ITU-R, the full English name is International Telecommunications Union-Radio Communications Sector) has promulgated international radio regulations. The wireless frequency bands used by various services and communication systems have been regulated in a unified frequency range. [0003] In the frequency band of about 570 megahertz (ie MHz) that has been clearly allocated, frequency division duplex (FDD, Frequency Division Dual) spectrum is about 480MHz (roughly distributed in the range of 700-2690MHz), time division duplex (TDD, TimeDivision Duplex) About 85MHz frequency band is a...
