Different-frequency-band carrier aggregation antenna and mobile terminal

The invention provides a different-frequency-band carrier aggregation antenna. The antenna comprises at least two antenna structures, at least two RF processing chips and at least two RF switches for connecting the antenna structures with the RF processing chips. Each antenna structure comprises a low-frequency sub antenna, a tuning structure of the low-frequency sub antenna, an intermediate and high frequency sub antenna and a tuning structure of the intermediate and high frequency sub antenna. Different antenna structures are connected with the corresponding RF processing chips via the different RF switches respectively. The invention also provides a mobile terminal. According to the antenna and mobile terminal, the low-frequency sub antennas are arranged in combination with the intermediate and high frequency sub antennas, and the compatibility with different frequency bands of signals of the carrier aggregation antenna is improved. 本发明提供种异频段的载波聚合天线，其包括至少两个天线结构、至少两个射频处理芯片以及用于连接所述天线结构以及至少两个射频开关；天线结构包括低频子天线、
