LTE antenna structure

The present invention provides a LTE (Long Term Evolution) antenna structure. The structure comprises a low-frequency radiation piece, a high-frequency radiation piece, a short circuit piece, a feed terminal and a first connection section and a second connection section of an impedance matching unit. The first end of the impedance matching unit is connected with the low-frequency radiation piece, the second end of the low-frequency radiation piece is connected with the feed terminal, the low-frequency radiation piece is configured to change the inductive character of the feed terminal to effectively improve the bandwidth of a LTE antenna structure in a low frequency band and reach a lower frequency so as to allow the LTE antenna structure to more accord with communication demands. The LTE antenna structure employs the impedance matching unit connected between the feed terminal and the low-frequency radiation piece to change the serial inductive character to effectively improve the bandwidth of a LTE antenna s
