1), owing to adopting 1 MPMT(multitool to throw more) duplexer (ASM, Antenna Switch) is by the antenna of the signal mixing more than two or two of the different frequency range of mobile terminal.In this case, the frequency range minimizing that single antenna is responsible for, corresponding Clearance requirement also can be less, consequently still obtains best antenna performance under severe conditions.
2), owing to adopting MPMT(multitool to throw more) duplexer or hilted broadsword throw duplexer more, by the transmitting and receiving of mobile terminal separately, different antennae of feeding respectively (antennas of more than two or two).Can be the antenna of transmitting and receiving difference design optimization specially.Improve mobile terminal radio frequency performance.
3), owing to adopting 1 multitool to throw duplexer or duplexer thrown by multiple hilted broadsword more, the different systems of mobile terminal (be can be, but not limited to: 1, GSM and 3G standard separately more; 2,3G and 4G standard is separated) different antennae of feeding respectively.Thus often prop up antenna be responsible for standard reduce, can optimizedly be this standard designing antenna.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection range that all should belong to claims of the present invention.
