Embodiment
Figure 1A is the schematic diagram of the electronics unit portion separation structure of one embodiment of the invention.Figure 1B is the schematic diagram of the antenna module of Figure 1A.Please refer to Figure 1A and Figure 1B, the electronic installation 10 of the present embodiment, comprises antenna module 100.Antenna module 100 is arranged at electronic installation 10 and in order to receive and dispatch at least one radiofrequency signal.Antenna module 100 comprises unipole antenna 110, passive antenna 120, transducer 130, connection line 140, matrix circuit 150, the first passive component 160 and the second passive component 170.The adjacent unipole antenna 110 of passive antenna 120 also couples the ground plane 12 of electronic installation 10.Transducer 130 couples unipole antenna 110 and passive antenna 120.Connection line 140 couples transducer 130, and in there is first end 142 and the second end 144 away from one end of transducer 130.First end 142 couples unipole antenna 110, the second ends 144 and couples passive antenna 120.Matrix circuit 150 is arranged at one end that passive antenna 120 connects ground plane 12.The first passive component 160, between transducer 130 and unipole antenna 110, and is arranged at one end that connection line 140 connects unipole antenna 110.The second passive component 170, between transducer 130 and passive antenna 120, and is arranged at the one end that connects passive antenna 120 in connection line 140.
In the present embodiment, electronic installation 10 can be panel computer, and antenna module 100 can be the LTE antenna in panel computer.Transducer 130 is proximity transducer (Proximity sensor), in order to the whether close electronic installation 10 of the outer human body of detection. electronics 10.Unipole antenna 110 presents the sheet metal of inverted L-shaped in conjunction with T shape for profile, and load point 112 is arranged at the turning point of sheet metal.But, the profile that the present invention does not limit unipole antenna at this, in the present invention, in other embodiment that do not illustrate, unipole antenna can be also the sheet metal of independent T shape profile.In the time that antenna module 100 is received and dispatched radiofrequency signal, for fear of affecting antenna resonance mode originally in order to the connection line 140 that unipole antenna 110 and passive antenna 120 is connected to transducer 130, the first passive component 160 is arranged on before unipole antenna 110 is connected to transducer 130, and the second passive component 170 is arranged on before passive antenna 120 is connected to transducer 130.In other words, the first end 142 that the first passive component 160 can be arranged on connection line 140 connects the position of unipole antenna 110, for example, be the position that has just departed from unipole antenna 110.The second end 144 that the second passive component 170 can be arranged on connection line 140 connects the position of passive antenna 120, for example, be the position that has just departed from passive antenna 120.Therefore, the antenna module 100 of the present embodiment can all not be connected with transducer 130 with passive antenna 120 because of unipole antenna 110 and resonance mode is originally affected, and matrix circuit 150 also can keep antenna module 100 to operate in resonance mode originally.
In addition, in Figure 1B, because in connection line 140, the second end 144 paths that connect passive antenna 120 are longer, and in order thoroughly to intercept passive antenna 120 and transducer 130, antenna module 100 more comprises the 3rd passive component 180.The 3rd passive component is established 180 and is placed in connection line 140 and is positioned at the side of the second end 144 away from relative the second passive component 170.In other words, the 3rd passive component 180 is for being arranged on second end 144 and first end 142 junction position before mutually of connection line 140.But the present embodiment does not limit antenna module 100 at this need arrange the 3rd passive component 180, in the present invention, in other embodiment that do not illustrate, the 3rd passive component also can be omitted.In the present embodiment, the first passive component 160, the second passive component 170 and the 3rd passive component 180 are all inductance, and inductance value is between 1nH to 50nH, for example, be 47nH.But, along with the difference of circuit and the environment of antenna, the inductance value difference to some extent of the first passive component 160, the second passive component 170 and the 3rd passive component 180, the present invention is not limited at this.
The antenna module 100 of the present embodiment, except transmitting-receiving signal of communication function originally, can also, by coupling using the sensing pad as transducer 130 with transducer 130, make electronic installation 10 not need additionally to arrange sensing pad again.Taking proximity transducer as example, the detection principle of transducer 130 is by being provided with near the surface of detection faces the sensing pad (graphic illustrating is two) that multi-disc sheet metal forms.When sensing pad by human body near time, the capacitance between sensing pad changes, and makes transducer 130 transmit signal and returns system, and reduce the radio-frequency power of system.
In the present embodiment, the unipole antenna 110 of antenna module 100 and passive antenna 120 can be served as the sensing pad of transducer 130.But, because passive antenna 120 is to pull out from ground plane 12, if will, using unipole antenna 110 and the sensing pad of passive antenna 120 as transducer 130, must intercept coupling of passive antenna 120 and ground plane 12.Therefore, antenna module 100 need disconnect passive antenna 120 and ground plane 12 by matrix circuit 150 and make unipole antenna 110 and passive antenna 120 can serve as the sensing pad of transducer 130, and producing capacitance variation near unipole antenna 110 during with passive antenna 120 as user, transducer 130 is done.Because being induced electricity capacitances, transducer 130 changes, so with regard to capacitive sensing, the matrix circuit 150 of the present embodiment can disconnect passive antenna 120 and ground plane 12 ground connection when avoiding passive antenna 120 as sensing pad, make unipole antenna 110 and passive antenna 120 all can be used as the sensing pad into transducer 130, and the sensing pad of transducer 130 more can make the sensing pad of transducer 130 have induction area and distance of reaction that maximum contains with the common structure of antenna module 100.Therefore, the antenna module 100 of the present embodiment can have logical signal of communication and the function as 130 sensing pad of transducer sent out concurrently, make electronic installation 10 not need additionally to arrange again sensing pad, for the elasticity that promotes electronic installation 10 interior space configuration, be very helpful.
