Abstract

The invention provides an antenna structure and a mobile terminal. The antenna structure comprises a feed source and an antenna radiator, wherein the antenna radiator is connected to the feed source; the antenna radiator includes at least one first antenna radiation portion which is in an umbrella structure; the first antenna radiation portion which is in the umbrella structure includes an antenna receiving port; and the antenna receiving port is far away from the feed source. In the invention, through a structure design of the first antenna radiation portion which is in the umbrella structure in the antenna radiator, a polarization mode of an antenna approaches circular polarization, a circular polarization signal sent by a GNSS satellite can be effectively received and polarization losses are reduced. Simultaneously, the antenna receiving port of the first antenna radiation portion is far away from the feed source so that radiation directivity of the antenna mainly points to an upper hemisphere; and a gain of the upper hemisphere is increased and signal receiving efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to an antenna structure and a mobile terminal. Background technique [0002] With the popularization of smart phones, people have more and more needs for mobile phone positioning and navigation, so the GNSS (Global Navigation Satellite System, Global Navigation Satellite System) of mobile phones, especially the performance of GPS (Global Positioning System, Global Positioning System) increasingly important. Under the trend of antenna design and radiation space getting smaller and smaller, and the shape design challenge is getting bigger and bigger. For example, the metal composition and ratio are getting more and more, and the performance of the antenna is often degraded. [0003] At present, most of the GNSS / GPS antenna solutions in mobile phones are a single built-in antenna for positioning. The implementation of the built-in GNSS antenna is metal sheet, FPC, LDS, metal...
