Example Embodiment

[0034] The difference between the first embodiment and the second embodiment is that the positions of the symmetrical slits on the metal frame are different. The symmetrical slits have a good appearance and conform to the aesthetic standards of consumers. Compared with the gap opening on the left and right sides, the gap opening at the bottom of the metal frame can avoid the contact between the hand and the gap when the portable device is used, and improve the communication quality. In addition, this solution can also be applied to an LTE carrier aggregation antenna structure without a metal frame.

[0035] Table 1 shows the number of carrier aggregation pairs of all frequency bands for out-of-band carrier aggregation. The table contains 12 pairs of frequency band numbers for different operating frequency bands. It can be seen from the table below that, except for the carrier aggregation of Band 3 and Band 7, the low-band frequencies of the other 11 pairs of carrier aggregation ...

Abstract

The invention discloses an LTE (Long Term Evolution) carrier aggregation antenna for portable type equipment with a metal framework. The LTE carrier aggregation antenna comprises a shell, a grounding plate, the metal framework and an antenna assembly, wherein the metal framework is symmetrically provided with a first gap and a second gap; the metal framework is divided into an upper frame section and a lower frame section by the first gap and the second gap; the antenna assembly comprises a radiation main body, a first feed part, a second feed part, a band-pass filter, a low-frequency matching module and a high-frequency matching module; the radiation main body is the upper frame section; the first feed part and the second feed part are located in an antenna clearance zone; the first feed part and the second feed part are parallel to each other; the first feed part is connected with the radiation main body by the low-frequency matching module; the second feed part is connected with the radiation main body by the high-frequency matching module. The LTE carrier aggregation antenna can support an out-of-band carrier aggregation antenna of an LET-A technology, the data transmission rate is extremely improved and the communication performance is good.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to an LTE carrier aggregation antenna for a portable device with a metal frame. Background technique [0002] With the rapid development of the LTE technology, more and more portable devices begin to support the LTE technology. In LTE antenna design, the antenna bandwidth requirements are: the low frequency bandwidth range is 698-960MHz, and the high frequency bandwidth range is 1710-2690MHz. A MIMO antenna is required in common LTE technologies. In order to further improve data transmission efficiency, LTE-A technology also needs to use carrier aggregation antennas. [0003] On the one hand, in order to increase the aesthetic effect of the outer surface of the mobile device, designers have begun to widely use metal decorative frames as frames. Recently, antenna structures based on metal frames have appeared on the market, but in most antenna structures based on metal fr...
