The invention provides a different-frequency-band carrier aggregation antenna. The different-frequency-band carrier aggregation antenna comprises at least two antenna structures and at least two radio frequency processing chips which are used for performing transmitting-receiving processing on data signals, wherein the antenna structures comprise a low-frequency sub antenna, a low-frequency sub antenna tuning structure, a medium-high-frequency sub antenna and a medium-high-frequency sub antenna tuning structure; the low-frequency sub antenna is used for receiving and transmitting a low-frequency data signal; the low-frequency sub antenna tuning structure is used for adjusting the communication frequency bands of the low-frequency sub antenna; and the medium-high-frequency sub antenna is used for receiving and transmitting a medium-high-frequency data signal; the medium-high-frequency sub antenna tuning structure is used for adjusting the communication frequency bands of the medium-high-frequency sub antenna, wherein the radio frequency processing chips are connected with the at least two antenna structures through radio frequency switches respectively. The invention also provides a mobile terminal. According to the different-frequency-band carrier aggregation antenna, and the mobile terminal provided by the invention, by virtue of the combination of the low-frequency sub antenna and the medium-high-frequency sub antenna, the compatibility of the carrier aggregation antenna on signals of different frequency bands is improved.
Description
technical field [0001] The present invention relates to the communication field, in particular to a carrier aggregation antenna of different frequency bands and a mobile terminal. Background technique [0002] Carrier Aggregation (CA) is a technology to increase the transmission bandwidth, which can aggregate 2 to 5 LTE (Long Term Evolution, long-term evolution) component carriers (CC) together to achieve the maximum The 100MHz transmission bandwidth effectively improves the uplink and downlink transmission rates. In carrier aggregation, it includes a primary carrier (PCC) and at least one secondary carrier (SCC). [0003] figure 1 It is a schematic structural diagram of an existing carrier aggregation antenna. The carrier aggregation antenna 10 includes an upper antenna structure 11 , a lower antenna structure 12 and a radio frequency processing module 13 , and the radio frequency processing module 13 is connected to the upper antenna structure 11 and the lower antenna st...
