1), owing to adopt 1 MPMT(multitool to throw more) duplexer (ASM, Antenna Switch) is the antenna of signal mixing more than two or two of the different frequency range of portable terminal.In this case, single the frequency range minimizing that antenna is responsible for, corresponding headroom requires also can be less, consequently still obtains best antenna performance under harsh conditions.
2), owing to adopt the MPMT(multitool to throw more) duplexer or hilted broadsword throw duplexer more, and portable terminal transmitted and received separately the different antennae of feeding respectively (antennas more than two or two).So that can be specially for transmitting and receiving the antenna of design optimization respectively.Improve the mobile terminal radio frequency performance.
3), owing to adopt 1 multitool to throw duplexer or a plurality of hilted broadsword is thrown duplexer more more, with the different systems of portable terminal (can but be not limited to: 1, GSM and 3G standard are separately; 2,3G and 4G standard are separated etc.) different antennae of feeding respectively.Thereby every antenna is responsible for standard and is reduced, so that can optimizedly be this standard designing antenna.
Should be understood that application of the present invention is not limited to above-mentioned giving an example, for those of ordinary skills, can be improved according to the above description or conversion that all these improvement and conversion all should belong to the protection range of claims of the present invention.
