In the present embodiment, as shown in Figure 6, the plane is formed at the top of the housing 35 of mobile phone main body.In housing 35, disposed printed circuit board (PCB) 36, with it the upper surface configured in parallel use the antenna assembly 19 of the described embodiment 1 that Fig. 1 illustrated.The conductor floor 17 of this antenna assembly 19 is replaced by the ground configurations portion 37 on the printed circuit board (PCB) of representing with Fig. 6 that is formed on mobile phone main body 34 36.
In addition, in mobile phone main body 34, power supply terminal 16 has been electrically connected near the electric power-feeding structure portion 38 the ground configurations portion 37 that is formed on printed circuit board (PCB) 36 by methods such as pressure welding, solderings.
According to this structure, on the basis of the effect of embodiment 1, from mechanical surge protection the housing of mobile phone main body 34.
Like this, just can realize the long lifetime of antenna assembly 19.Meanwhile, because do not need the match circuit of the impedance operator coupling usefulness of desirable frequency band, so can reduce the cost of mobile phone.
As previously discussed, by can be in the impedance operator that does not have easily to set under the situation of match circuit desirable frequency band, and broadband, the highly sensitive high small-sized slim antenna assembly of productivity, can obtain high performance wireless device.Meanwhile, from mechanical surge protection antenna assembly.
In addition, the design freedom height of mobile phone main body is not because need the match circuit of impedance operator coupling usefulness, so can fall the cost of wireless device.
(embodiment 7)
Fig. 7 represents the structure of the walking circuit of the embodiment of the invention 7.
In the present embodiment, as shown in Figure 7, the upper end of the printed circuit board (PCB) 41 in the housing 40 of mobile phone main body 39 has disposed antenna assembly 19A.Disposed antenna assembly 19B in the bottom of printed circuit board (PCB) 41.At this, antenna assembly 19A has adopted identical structure with antenna assembly 19B with the antenna assembly 19 of embodiment 1.
The power supply terminal 16A of antenna assembly 19A and antenna assembly 19B and 16B have been electrically connected the terminal 44A and the 44B of switch 43 of the high-frequency circuit portion 42 of mobile phone main body 39 respectively by methods such as pressure welding, solderings.
In addition, with described same, the part of conductor floor 17A and 17B has been electrically connected the ground configurations portion 45 on the printed circuit board (PCB) 41 that is formed on mobile phone main body 39.
In the mobile phone of present embodiment, compared the level of the reception electric power of antenna assembly 19A and antenna assembly 19B.Receive big antenna assembly and the high-frequency circuit portion 42 of electric power by connecting, constituted diversity communication device.
According to this structure, from mechanical surge protection the housing 40 of mobile phone main body 39.In view of the above, can make the life-span of antenna assembly 19A and 19B elongated.Meanwhile, by using the diversity communication mode, the human body in the time of suppressing to use mobile phone can obtain the excellent communications quality to the influence of the transmission receptivity of electric wave.
It should be noted that,, can improve the diversity communication performance by described two antenna assembly 19A and 19B being configured to the position relation of orthogonal direction.
In addition, by Built-in antenna apparatus, can improve the design freedom of mobile phone main body 39.Because do not need the match circuit of impedance operator coupling usefulness, so can fall the cost of wireless device.
As previously discussed, in this wireless device, do not having under the situation of match circuit, the impedance operator of desirable frequency band can easily be set.In addition, this wireless device carried two broadbands, highly sensitive, productivity is high and small-sized slim antenna assembly.Therefore, by the housing of wireless device, can be from mechanical surge protection antenna assembly.Meanwhile, can improve the design freedom of wireless device main body.Because do not need the match circuit of impedance operator coupling usefulness, so can fall the cost of wireless device.In addition, by the diversity feature of two antenna assemblies,, the big antenna assembly of reception electric power is worked even weak electric field also can compare two antenna assemblies.In view of the above, can improve wireless device with good speech quality.
Utilizability on the industry
As previously discussed, according to the present invention, can realize small-sized slim, broadband, high-sensitivity, Multiband, can provide the productivity that can easily carry out impedance matching high can be built-in day traditional thread binding Put.
In addition, by built-in antenna assembly of the present invention in wireless device, can be from from the outside Protect antenna assembly under the mechanical shock. Simultaneously, make the corresponding multiband of wireless device energy, can realize wide Band, high sensitivity.
In addition, the antenna assembly equipped section in the wireless device divides required space to diminish. Accordingly, can Hope the small-sized slimming that realizes wireless device. Meanwhile, easily obtain and desirable frequency band Corresponding impedance operator. Therefore, need to be by LC element structure in the high-frequency circuit section of wireless device The impedance matching circuit of the complexity that becomes, thus cheap wireless device can be provided.
