Antenna for mobile phone and mobile phone with antenna

Abstract

The invention discloses an antenna for a mobile phone and the mobile phone with the antenna. The antenna for the mobile phone comprises a mobile phone middle shell, an excitation sheet, a dielectric filling layer and a matching network, wherein the mobile phone middle shell comprises a metal middle support plate and a metal frame; the metal middle support plate is provided with a support plate transverse gap and a support plate longitudinal gap; a frame transverse gap is formed in the metal frame; the excitation sheet comprises a feed structure and a third radiation path; the feed structure covers the support plate transverse gap in the width direction of the support plate transverse gap; the dielectric filling layer is arranged between the excitation sheet and the metal middle support plate and the support plate transverse gap, the support plate longitudinal gap and the frame transverse gap are filled with the dielectric filling layer; and the matching network is connected with the feed structure and the metal middle support plate separately. The antenna for the mobile phone disclosed by the embodiment of the invention is relatively large in bandwidth, can meet 2G, 3G and 4G communication and is simple in structure, low in cost and small in loss, the thickness of the mobile phone can be reduced and the appearance of the mobile phone can be improved.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular, to an antenna for a mobile phone and a mobile phone with the antenna for a mobile phone. Background technique [0002] With the development of smart phones and communication technologies, people tend to use metal mobile phones more and more, and at the same time require faster communication quality. Today's communication electronic equipment usually needs to cover 2G, 3G and 4G networks at the same time. The communication bandwidth requirement is very wide, and the communication frequency needs to be covered (791-960MHz, 1710-2690MHz). For mobile phones with metal frames, the antenna design is difficult and the performance is difficult to meet Require. [0003] In the related art, two parallel gaps are opened on the metal frame connected to the PCB board to form three loop radiations, and an electronic switch switching circuit is set to widen the bandwidth to meet ...

AI Technical Summary

Problems solved by technology

This kind of mobile phone antenna is not only complicated in structure, but also the setting of electronic switches increases the cost and loss. In addition, the antenna body part needs to be set on the bracket. The height of the bracket limits the thickness of the mobile phone and cannot be made thinner. The setting of the gap also affects the appearance of the mobile phone.
