Detailed description of the invention
Fig. 1 is the electronic installation 1(hereinafter referred to as electronic installation 1 of the eliminated interference in a preferred embodiment of the present invention)
Hardware Organization Chart, this electronic installation 1 can be arbitrary electronic product with wireless communication function, such as mobile phone or flat board
Computer.
This electronic installation 1 includes one first radio component 10 and one second radio component 20, this first radio unit
Part 10 and the second radio component 20 work on the same frequency band.Wherein, this first radio component 10 includes first antenna
11 and first sending and receiving end 12, this second radio component 20 includes the second antenna 21 and the second sending and receiving end 22, and wherein, this first is received
Make a start 12 the first signals launched by its first emission port 120 via first antenna 11 and the second antenna 21 simultaneously to freedom
Space sends；The secondary signal that this second sending and receiving end 22 is launched by its second emission port 220 is via first antenna 11 and the
Two antennas 21 send to free space simultaneously.In the present embodiment, the first radio component 10 uses bluetooth (Bluetooth)
Short distance radio communication standards, such that it is able to any long-range receiving terminal communication in 10 meters of radius；Second radio unit
Part 20 uses the WiFi short distance radio communication standards of IEEE 802.11b, such that it is able to any use IEEE 802.11b/
The receiving terminal communication of g/n.In the present embodiment, this first antenna 11 and the second antenna 21 be disposed as aerial array (such as 1 ×
2 aerial arrays), it is used for improving antenna gain.
Owing to described first radio component 10 and the second radio component 20 worked, on the same frequency band at first day
Under coupling between line 11 and the second antenna 12, the first radio component 10 the first signal launched and the second radio
The secondary signal that element 20 is launched is likely to result in and interferes (i.e. internal interference)；If additionally, carrying out nothing with this electronic installation 1
The radio transmission bands of another electronic product of line communication and this first radio component 10 and the second radio component 20
Frequency band is identical, then when this first radio component 10 and this second radio component 20 work simultaneously, and the first radio component 10
Or this second radio component 20 also can be by the signal disturbing (i.e. external disturbance) of this electronic product.That is, the first sending and receiving end 12
May receive from first antenna 11 and the mixed signal of the second antenna 21, this mixed signal includes first antenna 11 and second
Any desired signal, external interference signals and the internal interference signals from the second sending and receiving end 22 that antenna 21 receives；The
Two sending and receiving ends 22 are likely to receive from first antenna 11 and the mixed signal of the second antenna 21, and this mixed signal includes first
Any desired signal, external interference signals and the inside from the first sending and receiving end 12 that antenna 11 and the second antenna 21 receive
Interference signal.
This electronic installation 1 still further comprises orthocoupler 30,1 first two-way phase switcher 41 and one second pair
To the phase shifter 42.Wherein, this orthocoupler 30 and the first emission port 120 and the second sending and receiving end 22 of this first sending and receiving end 12
