Description
Technical field
The present invention relates to wireless communication technology field, more particularly to a kind of antenna system and antenna switching method.
Background technology
Currently, in order to improve the aesthetic appearance of terminal device (such as mobile phone, tablet computer) and touch texture, in the industry often
For terminal device, metal shell (or metal edge frame) is set.But since the antenna that existing most terminal devices use is
Built-in aerial, and certain shielding action that complete metal material can generate signal, thus in order to enable terminal device
Antenna being capable of normal receiving and transmitting signal, it usually needs is cracked (such as side to the metal rear shell (or metal edge frame) of terminal device
Side and/or bottom edge), a part of the metal rear shell (or metal edge frame) as terminal device antenna after cracking.
Specifically, terminal device may include one as the upper antenna of diversity reception antenna and a main collection dual-mode antenna of conduct
Lower antenna can be by upper and lower antenna intelligence handoff technique when user holds terminal device and blocks the lower antenna in part, will be upper
Collect dual-mode antenna based on antenna switching, lower antenna is switched to diversity reception antenna.For example, as shown in Figure 1, (it is the prior art
In antenna system 700 structural schematic diagram), it is assumed that the antenna system 700 of terminal device may include antenna 101, pair net
Network 102, PCB (Printed Circuit Board, printed circuit board) cabling 103, DPDT (Double Pole Double
Throw, double-pole double throw) (wherein, the moving contact of the DPDT104 is 1,2 to switch 104；Static contact be 1., 2., 3., 4.), PCB
Cabling 105, diversity receiver 106, main collection transceiver 107, matching network 108 and lower antenna 109 then are needing to carry out up and down
When switching (i.e. upper antenna performance is preferable, lower antenna performance is poor) of antenna, the moving contact 1 of DPDT104 can be placed in static contact
3. it is upper, the moving contact 2 of DPDT104 is placed in static contact 4. on, the wireless network signal that upper antenna 101 receives is sent to
Main collection transceiver 107 (or sending out the wireless network signal that main collection transceiver 107 is sent out by upper antenna 101), by lower antenna
109 wireless network signals received are sent to diversity receiver 106, at this point, between upper antenna 101 and main collection transceiver 107,
It may include may include PCB trace 105 between PCB trace 103, lower antenna 109 and diversity receiver 106；Need not carry out on
When the switching of lower antenna, the moving contact 1 of DPDT104 can be placed in static contact 1. on, the moving contact 2 of DPDT104 is placed in stationary contact
Head 2. on, the wireless network signal that upper antenna 101 receives is sent to diversity receiver 106, lower antenna 109 is received
Wireless network signal be sent to main collection transceiver 107 and (or the main wireless network signal that sends out of collection transceiver 107 passed through into lower day
Line 109 is sent out).But at this point, due to the cabling between upper antenna 101 and diversity receiver 106 include PCB trace 103 and
PCB trace 105, thus can there is a problem of that cabling is long.
In conclusion existing antenna system 700 need not carry out up and down antenna switching when, can exist cabling it is long,
The problem that loss of signal is larger and antenna performance is bad.
