Embodiment
Fig. 1 is the structural representation of the communicator according to one embodiment of the invention.As shown in Figure 1, communicator 100 comprises earth element 10 and an antenna element 11.One edge 101 of the contiguous earth element 10 of antenna element 11, and form an annular (loop) structure with edge 101.Antenna element 11 comprises one first metal section 12 and one second metal section 13.First metal section 12 has first end 121 and one second end 122, and first end 121 is one first load point of antenna element 11.Second metal section 13 has one the 3rd end 131 and one the 4th end 132, and the second metal section 13 also has one second load point 133 of antenna element 11.Wherein, the 4th end 132 of the second metal section 13 is electrically connected to earth element 10 via a short circuit metallic portion 14.In addition, the second load point 133 is away from the 3rd end 131 of the second metal section 13, and the 4th end 132 of contiguous second metal section 13.
Further, communicator 100 also comprises one first diverter switch 151,1 second diverter switch 152, capacity cell 18 and a communication module 19.Wherein, the 3rd end 131 of the second metal section 13 is electrically connected to the second end 122 of the first metal section 12 via the first diverter switch 151.The first end 121 of the first metal section 12 (that is, the first load point) be electrically connected to communication module 19 via capacity cell 18.Second load point 133 of the second metal section 13 is electrically connected to communication module 19 via the second diverter switch 152.
Operationally, communication module 19 can switch the state of the first diverter switch 151 and the second diverter switch 152, forms a loop aerial (loop antenna) or an inverted-F antenna (inverted-F antenna) to cause antenna element 11.In addition, communication module 19 understands the state in response to the first diverter switch 151 and the second diverter switch 152, and transmit FD feed to the first load point (that is, the first end 121 of the first metal section 12) or the second load point 133, with excitation antenna element 11 by this, and antenna element 11 is caused to operate in one first frequency band or one second frequency band.
For example, when the first diverter switch 151 conducting, and during the second diverter switch 152 not conducting, the edge 101 of the first metal section 12, second metal section 13, short circuit metallic portion 14 and earth element 10 is by formation one loop aerial structure.In other words, when the first diverter switch 151 conducting, and during the second diverter switch 152 not conducting, antenna element 11 is by formation one loop aerial, and antenna element 11 is now via the first load point (that is, the first end 121 of the first metal section 12) feed in energy analysis.Therefore, communication module 19, by transmitting first load point of a FD feed to antenna element 11 via capacity cell 18, operates in the first frequency band to cause antenna element 11.
On the other hand, when the first diverter switch 151 not conducting, and during the second diverter switch 152 conducting, the second metal section 13 and short circuit metallic portion 14 are by formation one inverted-F antenna structure.In other words, when the first diverter switch 151 not conducting, and during the second diverter switch 152 conducting, antenna element 11 is by formation one inverted-F antenna, and antenna element 11 is now via the second load point 133 feed in energy analysis.Therefore, the second diverter switch 152 via conducting is transmitted second load point 133 of FD feed to antenna element 11 by communication module 19, operates in the second frequency band to cause antenna element 11.
It is worth mentioning that, communicator 100 increases the frequency range of the operational frequency bands of antenna element 11 by least one match circuit.Such as, as shown in Figure 1, in one embodiment, communicator 100 also comprises one first match circuit 16 and one second match circuit 17.Wherein, the first match circuit 16 is electrically connected between capacity cell 18 and communication module 19, and the second match circuit 17 is electrically connected between the second diverter switch 152 and communication module 19.When antenna element 11 operates in the first frequency band, the first match circuit 16 in order to improve the impedance matching of the first frequency band, and then can expand the frequency range of the first frequency band.In addition, when antenna element 11 operates in the second frequency band, the second match circuit 17 in order to improve the impedance matching of the second frequency band, and then can expand the frequency range of the second frequency band.
It should be noted that antenna element 11 can be reassembled as a loop aerial or an inverted-F antenna.Wherein, inverted-F antenna formed by the partial section of loop aerial, and the feed-in structure of inverted-F antenna (that is, the second load point 133) be the inside being positioned at loop aerial.In other words, the size of antenna element 11 mainly determined by loop aerial.In addition, antenna element 11 when not increasing the overall dimensions of antenna element 11, can be reassembled into an inverted-F antenna from loop aerial by communicator 100.
On the other hand, capacity cell 18 can reduce the resonant length of loop aerial effectively, and then contributes to the size reducing antenna element 11.Moreover, compared with the general mode using the inductance element of high inductance value to reduce the size of antenna element, capacity cell is used to reduce the mode of the size of antenna element, the high ohmic loss that the inductance element because of high inductance value produces can be avoided, and then avoid the problem of the radiation efficiency reducing antenna.On the other hand, primary structure due to antenna element 11 is loop aerial, and loop aerial operationally there is no openend, therefore antenna element 11 can reach the advantage of low form (low-profile), and then contributes to the development of communicator 100 on thin type.
