Abstract

The invention discloses a terminal antenna frequency band extension structure comprising a metal rear cover and a metal middle frame. The metal middle frame is arranged around the metal rear cover, and the metal rear cover and the metal middle frame form an integrated structure. The two ends of the integrated structure are provided with seams. The integrated structure is separated into two antenna radiators and a back metal plate by the seams. The two antenna radiators are respectively provided with a first grounding point, a feed point and a second grounding point. The antenna radiators are enabled to generate low frequency band bandwidth and high frequency band bandwidth through resonance by controlling disconnection and connection of the two first grounding points. The terminal antenna frequency band extension structure also comprises metal coupling sheets which are arranged at the target positions around the feed points so as to extend the low frequency band bandwidth or the high frequency band bandwidth through coupling between the metal coupling sheets and the antenna radiators, wherein the metal coupling sheets are parallel to the top part or the bottom part of the metal rear cover.

Description

technical field [0001] The invention relates to antenna technology, in particular to a frequency band extension structure of a terminal antenna. Background technique [0002] With the fourth generation (4G, 4 th Generation) communication technology is developing rapidly, and current mobile terminals are increasingly supporting 4G networks, such as Long Term Evolution (LTE, Long Term Evolution) networks, which require antennas to have wider bandwidths to meet user needs. On the other hand, with the further popularization of 4G terminals, the homogenization of mobile phones is becoming more and more serious, and people have higher and higher requirements for mobile phones, such as: the texture of the body, the user's online experience, etc. For this reason, many mobile phone manufacturers have launched metal models. Among them, all-metal integrated mobile phones are popular among consumers because of their beautiful appearance, high structural strength, and superior thermal ...
