In the present embodiment, the bottom of carrier 52 includes two turnings, and above-mentioned turning includes the first turning and the second turning, First turning and the second corner have a recess, and radiator 51 is arranged on the bottom of carrier 52, radiator 51 include body part and Extension positioned at body part both ends, the body part of radiator 51 is parallel with the bottom of carrier 52, the extension of radiator 51 Do not extend to the first turning of carrier 52 and the second turning.
Among an embodiment, antenna module 100 can also include:Base band module 552,553 and of first sensor module Second sensor module 554, first end and the radio frequency module 551 of base band module 552 are electrically connected, and the second of base band module 552 End is electrically connected with first sensor module 553, and the 3rd end and the second sensor module 554 of base band module 552 are electrically connected, The other end of first sensor module 553 and second sensor module 554 is electrically connected with radiator.Wherein, the first sensing Device module 553 is electrically connected with radiator 51 at the first tie point, and second sensor module 554 connects with radiator 51 second Junction is electrically connected, and the first tie point is located at the one side of the first earth point, and away from the second earth point, the second tie point is located at The one side of second earth point, and away from the first earth point.
The operation principle of antenna module provided by the embodiments of the present application is, when no human hand close to when, first sensor mould The capacitance that group 553 and second sensor module 554 sense is C0, and the left side feed point 511 on radiator 51 is held when human hand When, the capacitance that first sensor module 553 senses at this time is CX, when the capacitance that first sensor module 553 receives becomes When change value CX-C0 reaches predetermined threshold value, control switch 544, which will control, switches over the feed point position of antenna.
Specifically, using the body of first antenna and the second antenna as sensor and respectively with first sensor module 553 Be electrically connected with second sensor module 554, first sensor module 553 and second sensor module 554 again with base band module 552 are electrically connected the capacitance received being sent to base band module 552.Base band module 552 is electrical with radio frequency module 551 Connection is for the above-mentioned control switch 554 of indirect control.In other embodiments, as shown in figure 8, base band module 552 can be with It is directly electrically connected with control switch 544, for control switch 554 for controlling the feed point position of antenna, above-mentioned feed point position is specific Including the first feed point 511 and the second feed point 512.
For example, the present embodiment can be set the antenna feed point under original free space to the first feed point 511. namely control Switch 544 connects port1 ports, when user holds the bottom of electronic equipment respectively using left hand and the right hand, first antenna sense The capacitance that should be arrived is respectively C1 and C1 ', by the variable quantity of the value of C1 '-C0 namely capacitance be set to control switch 544 by Port1 switches to the threshold value of port2, because when the right hand of user holds the bottom of electronic equipment, hand is to first antenna Influence bigger.In actual use, when first sensor module 553 detects that the value of above-mentioned C1 '-C0 reaches threshold value, then By controlling switch 544 that first feed point 511 is switched to the second feed point 512, the port1 of switch 544 will also be controlled to switch to port2。
Similarly, when antenna feed point is located at the right side of electronic equipment namely control switch 544 connects port2 ports, by day Line feed point is set to the second feed point 512, and the antenna of electronic equipment bottom is divided into third antenna and the 4th antenna at this time, can regard as by Using the body of third antenna and the 4th antenna as sensor and respectively with first sensor module 553 and second sensor module 554 are electrically connected.When user holds the bottom of electronic equipment respectively using left hand and the right hand, capacitance that the 4th antenna induction arrives Value is respectively C2 and C2 ', and the variable quantity of the value of C2-C0 namely capacitance is set to control switch 544 is switched to by port2 The threshold value of port1, because when the bottom of the left-handed electronic equipment of user, hand is to the influence bigger of the 4th antenna. Among actual use, when second sensor module 554 detects that the value of above-mentioned C2-C0 reaches threshold value, then switched by controlling Second feed point 512 is switched to the first feed point 511 by 544, and the port2 of switch 544 will also be controlled to switch to port1.
In one embodiment, if when first sensor module 553 and second sensor module 554 all sense it is current Capacitance variations value reaches corresponding threshold value, at this time can be by antenna feed point by the way that switch 544 is controlled to be arranged to the first of left side Feed point 511 or the second feed point 512 for being arranged to right side.For example, when both hands grip the bottom of electronic equipment simultaneously, antenna is selected Antenna performance is best under performance best one or free space one.
