Abstract

The invention relates to a terminal LDS antenna system and a mobile terminal. The terminal LDS antenna system comprises an antenna feed source, a single-pole double-throw switch, a first feed connection point and a second feed connection point. The LDS antenna unit comprises a metal outer frame, a metal middle frame arranged in the metal outer frame and an LDS metal pattern layer, the edge part ofthe LDS metal pattern layer is connected with the metal middle frame, and a branch knot structure is arranged at the bottom of the metal outer frame; the first feed connection point is arranged on the LDS metal pattern layer, and the second feed connection point is arranged on the metal middle frame; a moving contact of the single-pole double-throw switch is connected to an antenna feed source, one static contact of the single-pole double-throw switch is connected to a first feed connection point, and the other static contact of the single-pole double-throw switch is connected to a second feed connection point.

Description

Technical field [0001] This application belongs to the field of wireless communication technology, and in particular relates to a terminal LDS antenna system and a mobile terminal. Background technique [0002] With the Ministry of Industry and Information Technology officially issuing 5G commercial licenses to China Telecom, China Mobile, China Unicom and China Radio and Television this year, China has officially entered the 5G era. As for the frequency resources of 5GFR1 (Sub-6GHz band), China Mobile has obtained 5G test frequency resources in the 2515MHz-2675MHz and 4800MHz-4900MHz bands; China Unicom has obtained 5G test frequency resources with a total bandwidth of 3500MHz-3600MHz and a total of 100MHz bandwidth; China Telecom has obtained 3400MHz. -3500MHz 5G test frequency resources with a total bandwidth of 100MHz, and their frequency ranges correspond to the three frequency bands N41, N78 and N79 respectively. [0003] Publication number CN107331979A discloses an antenna ...
