The mobile phone of formula, it usually needs four antennas of configuration: vice card global system for mobile communications (English: Global System for
Mobile Communication, abbreviation: GSM) antenna, main card code division multiple address communication system (English: Code Division
Multiple Access, abbreviation: CDMA) antenna, the main collection antenna of main card B26, main card B26 diversity antenna.Optimal situation
It is that four antennas are respectively set in mobile phone, as shown in Figure 1.But increase an antenna, it is meant that need in terminal more
In equipment occupy an antenna space, will result in this way terminal device volume increase, for it is some require it is portable, light
Thin, beautiful terminal device is unacceptable.Also, in new terminals, especially with the terminal of metal shell
Equipment, it is all extremely difficult for having more some days space of lines and mostly one antenna of design.

Circuit of uniting uses.
In this way, the antenna resources that the second communication system circuit 304 (LTE system) obtains are as follows: when the first communication system circuit
302, when third communication circuit system 305 is idle, while first antenna 306 and the second antenna 307 is obtained and (can satisfy at this time
The demand that the main subsystem 304a of B26 and B26 diversity subsystem 304b are worked at the same time)；When the first communication system circuit 303 or the
When one of them free time of three communication system circuits 305, correspondingly obtain the second antenna 307 or first antenna 306 (can expire at this time
The demand of one of sufficient main sub- communication system circuit 304b of collected works communication system circuit 304a and B26 diversity of B26 work)；
When the first communication system circuit 302, third communication circuit system 305 work, there is no antenna (the main collected works of B26 at this time
System 304a and B26 diversity subsystem 304b does not work).
Please refer to Fig. 4, further, in order to which the antenna resources for obtaining the second communication system circuit 304 exist
Flexible allocation between two sub- communication system circuits, the second switching sub-circuit 309 carry out the distribution of antenna resources are as follows: when first logical
When letter circuit system 303 works and occupies first antenna 306, the second of the control circuit 301 control the second switching sub-circuit 309
Control terminal 309b is connect with the first connecting pin 309c, and the first control terminal 309a is connect with second connection end 309d.When the first communication
When circuit system 303 is idle, the first control terminal 309a of the control circuit 301 control the second switching sub-circuit and the first connecting pin
309c is connected, and the second letter control terminal 309b is connected with second connection end 309d.
Therefore, the main subsystem 304a of the B26 of the second communication system circuit 304 farthest obtains antenna resources:
When the first communication system circuit 303 (gsm system) and (cdma system) staggering time of third communication circuit system 305 work,
The main subsystem 304a of B26 always has assignable antenna resources；When the first communication system circuit 303 (gsm system) and third are logical
When letter circuit system 305 (cdma system) works at the same time, the main collected works communication system circuit 304a of B26 does not have assignable antenna to provide
Source inevitably occurs signal " falling hole ", and " hole is wide " and the first communication system circuit 303 (gsm system and cdma system phase
Than occupy the antenna time it is shorter) occupy first antenna 306 time it is identical, so that system loss is preferably minimized.
