Embodiment Construction

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] as attached Figure 1-5 As shown, a novel wide-band LTE antenna suitable for mobile terminals provided by the present invention includes a PCB board and an antenna part of a mobile terminal, wherein the PCB board includes a PCB metal coverage area 1 and a PCB clearance area 2, and the PCB metal Coverage area 1 is the non-clearance area. The clearance area is the area around the antenna on the PCB board and the projection plane perpendicular to the PCB without any devices and metal distribution. The non-clearance area refers to the area on the PCB that does not meet the definition of clearance area. .

[0031] In this embodiment, the maximum distance from the antenna part to the PCB board is 5 mm to 10 mm, the length of the non-clear area is 112 mm, and the width is 60 mm. The length of the headroom area is 60 mm and the width is 8 mm. th...

Abstract

The invention relates to a novel broadband LTE antenna suitable for a mobile terminal. A feeding point is located in the middle of a clearance zone. A first short-circuit point and a second short-circuit point are located at the two sides of the feeding point and a third short-circuit point and the feeding point are located at the two sides of the first short-circuit point. A first radiation body and a second radiation body are two symmetric E-type structural radiation bodies, one end of the first radiation body is connected with one end of the second radiation body, the other end of the first radiation body is connected with the feeding point, the other end of the second radiation body is connected with the first short-circuit point, and therefore a radiation body of the antenna is formed. A high-frequency coupler is connected with the second short-circuit point and after the first radiation body is coupled with the high-frequency coupler, an LTE high frequency of a broadband is generated. A low-frequency coupler is connected with the third short-circuit point and after the low-frequency coupler is coupled with the second radiation body, an LTE low frequency of the broadband is generated. According to the novel broadband LTE antenna, the requirement that the broadband LTE antenna within the LTE whole-frequency section coverage area is achieved on the mobile terminal is satisfied and an LTE mobile terminal system is wide in application prospect.

Description

technical field [0001] The present invention relates to an antenna, in particular to a novel broadband LTE (Long Term Evolution) antenna suitable for mobile terminals. Background technique [0002] With the continuous development of mobile communication networks in recent years, people have higher and higher requirements on mobile terminals. The simple voice communication and SMS in the past can no longer meet people's daily needs, and the accompanying multimedia, online games, video-on-demand and mobile TV and other large-flow data services have also developed rapidly, which requires mobile terminals to have more and more In order to meet the multiple functions, the antenna of the mobile terminal also needs to cover enough frequencies to meet the multi-functional requirements. [0003] The current mainstream communication terminal frequency bands are GSM850, GSM900, DCS1800, PCS1900, WCDMA2100, and the covered frequency range is low frequency 824MHz to 960MHz and high freq...
