LTE coupling type mobile phone antenna with metal frame

Abstract

The invention relates to an LTE coupling type mobile phone antenna with a metal frame. The LTE coupling type mobile phone antenna comprises a dielectric slab arranged in a mobile phone, an antenna radiator and the metal frame on the periphery of the dielectric slab. The metal frame can be a continuous and complete quadrilateral frame and can also be a quadrilateral frame with an open upper side corner. Gaps are formed between the periphery of the dielectric slab and the metal frame. The dielectric slab is divided into a clearance area and a laying area, the antenna radiator is arranged in the clearance area, one crossbeam, a left side beam and a right side beam of the metal frame are each provided with a grounded short dot, and the metal frame is connected with the laying area on the dielectric slab through the grounded short dots. A monopole antenna is adopted for the antenna radiator. According to the LTE coupling type mobile phone antenna, the metal frame is effectively utilized, multiple frequency bands can be covered with the antenna through body type changes of the antenna and other aided design, influences of the metal frame of a communication terminal on antenna performance are eliminated, excellent performance of the antenna is guaranteed, and meanwhile integrity of the metal frame is maintained as much as possible.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to an LTE antenna design scheme using a metal frame as a part of the antenna. Background technique [0002] With the vigorous development of information technology, people's demands for electronic products are becoming more and more diverse, and metal textured mobile phones have become one of many popular designs. The mobile phone adopts the design form of the metal frame, the structure is stronger, and the weight of the mobile phone can also be reduced. However, the existence of the metal frame will cause greater interference to the antenna of the mobile phone, and the performance of the antenna will be more affected than the metal devices in the mobile phone. [0003] At present, in order to eliminate the impact of the metal frame on the performance of the mobile phone antenna, the general method is to disconnect several openings on the metal frame, so that the discon...

However, the existence of the metal frame will cause greater interference to the antenna of the mobile phone, and the performance of the antenna will be more affected than the metal devices in the mobile phone.

[0003] At present, in order to eliminate the impact of the metal frame on the performance of the mobile phone antenna, the general method is to disconnect several openings on the metal frame, so that the disconnected part of the metal frame becomes a part of the antenna. This method destroys the continuity of the metal frame and affects The overall aesthetics of the mobile phone, and when the hands or other conductors hold the seam on the frame, the performance of the antenna will deteriorate sharply, resulting in poor transmission and reception
