The hybrid network that sense network is combined with capacitance network, the embodiment of the present invention is not limited in any way to this.
Below, citing is introduced in detail to the method for controlling antenna described in the embodiment of the present invention one:
For example, it is assumed that terminal device received by upper antenna 201 (i.e. first antenna) the first of wireless network signal
Signal strength signal intensity is -70db, the secondary signal intensity of the wireless network signal being received by lower antenna 210 (i.e. the second antenna)
For -90db, and described predetermined threshold value is 10db, then can determine that between described first signal strength signal intensity and described secondary signal intensity
Difference is 20db (20db ＞ 10db), therefore, can carry out the switching of the antenna up and down of described terminal device, to ensure terminal device
The intensity of wireless network signal of transmitting-receiving and quality.That is, the moving contact 1 of controllable dpdt203 (i.e. second switch) and stationary contact
3. head turns on, controls the moving contact 2 of dpdt203 and 4. static contact turns on, controls the moving contact 1 of dpdt207 (i.e. first switch)
3. turn on static contact and control the moving contact 2 of dpdt207 4. to turn on so that upper antenna 201 can be used as terminal with static contact
The main collection dual-mode antenna of equipment, lower antenna 210 can not repeat to this as the diversity reception antenna of terminal device.
Again for example, it is assumed that the first signal strength signal intensity of wireless network signal that terminal device is received by upper antenna 201 be-
70db, the secondary signal intensity of the wireless network signal being received by lower antenna 410 is -50db, and described predetermined threshold value is
10db, then can determine that the difference between described first signal strength signal intensity and described secondary signal intensity is -20db (20db≤10db),
Therefore, the switching of the antenna up and down of described terminal device can be carried out.That is, the moving contact 1 of controllable dpdt203 and static contact
1. 1. the moving contact 1 that 2. conducting, the moving contact 2 of control dpdt203 turned on, controlled dpdt207 with static contact is turned on static contact
And control the moving contact 2 of dpdt207 and static contact 2. turn on (now, the moving contact 1 of dpdt203 and static contact 1.,
The moving contact 2 of dpdt207 and static contact 2. between do not have wireless network signal by) so that upper antenna 201 can set as terminal
Standby diversity reception antenna, lower antenna 210 can be used as the main collection dual-mode antenna of terminal device.Described in background technology
Method of controlling antenna, in the switching not needing to carry out upper and lower antenna, upper antenna 201 need not pass through pcb cabling 205, dpdt207
And pcb cabling 206 sends the wireless network signal receiving to diversity signal access point 204 (i.e. diversity receiver), and
Only need to be by the dpdt203 close together with diversity signal access point 204 (i.e. diversity receiver) by the wireless network receiving
Signal sends to diversity signal access point 204, thus effectively having shortened the pcb cabling on mainboard, having reduced signal transmission
It is lost, improves the performance of terminal device antenna.
Further, in order to quickly and conveniently realize the intelligence switching to the upper and lower antenna of terminal device, described antenna system
May also include a control unit, described control unit can design corresponding software algorithm to control respectively switch in antenna structure to lead
Understanding and considerate condition, such as when switch control pin is for low level signal (as 0), can control the first moving contact (i.e. rfc1 of dpdt switch
End) and the first static contact (i.e. rf1 end, the 1. end described in Fig. 3) conducting, the second moving contact (i.e. rfc2 end) and the second static contact
(i.e. rf2 end) turns on, and that is, when switch control pin is for low level, does not execute the antenna switching operations up and down of terminal device；?
When switch control pin is high level (as 1), the first moving contact (i.e. rfc1 end) and the 3rd static contact (i.e. rf3 that dpdt switchs
Hold) turn on, the second moving contact (i.e. rfc2 end) is turned on the 4th static contact (i.e. rf4 end), that is, electric for height in switch control pin
At ordinary times, the antenna switching operations up and down of terminal device are executed.
Certainly, it should be noted that also dpdt switch can be controlled when switch control pin is for high level signal (as 1)
The first moving contact (i.e. rfc1 end) and the first static contact (i.e. rf1 end) turn on, the second moving contact (i.e. rfc2 end) is quiet with second
Contact (i.e. rf2 end) turns on, and that is, when switch control pin is for high level, does not execute the switching behaviour of antenna up and down of terminal device
Make；When switch control pin is for low level (as 0), the first moving contact (i.e. rfc1 end) and the 3rd static contact that dpdt switchs
(i.e. rf3 end) turns on, and the second moving contact (i.e. rfc2 end) is turned on the 4th static contact (i.e. rf4 end), that is, in switch control pin
During for low level, the antenna switching operations up and down of execution terminal device, this is not limited in any way.
In addition, it is necessary to explanation, the covering of the first antenna 201 described in the embodiment of the present invention and the second antenna 210
