Abstract

The present invention provides an antenna and a mobile terminal, wherein the antenna includes: a feed source, a combiner, an antenna radiator, a first antenna switch, a first matching network, a second matching network and a third matching network; A break is provided, and the antenna radiator forms the first radiator and the second radiator through the break; the input end of the combiner is connected to the feed source, and the first output end of the combiner is connected to the first end of the first matching network connected, the second output end of the combiner is connected to the first end of the second matching network; the second end of the first matching network is connected to the first radiator, and the second end of the second matching network is connected to the second radiator ; The first end of the first antenna switch is connected to the first radiator, and the second end of the first antenna switch is connected to the first end of the third matching network; the second end of the third matching network is grounded. The present invention can better take into account the bandwidth of each mode while realizing multiple CAs, and is applicable to mobile terminals with high screen-to-body ratios.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an antenna and a mobile terminal. Background technique [0002] With the launch of high-screen-to-body mobile terminals such as full-screen mobile phones, consumers have increasingly strong demands on the appearance of high-screen-to-body mobile terminals. A mobile terminal with a high screen-to-body ratio means that the headroom of the antenna will be further reduced (the headroom can be understood as the X / Y distance from the inner wall of the antenna radiator to the metal object supporting the wrapping screen, and the size of the headroom is proportional to the performance of the antenna and the signal strength). In addition, at present, operators have increasingly strong requirements for mobile terminals to support multi-band inter-band CA. For example, China Mobile's B39 (1.88-1.92GHz) + B41 (2.55-2.65GHz) inter-band CA (CarrierAggregation, carrier aggregation),...
