Part is grounded, and antenna matched using MA antenna-matching circuits as shown in Figure 5, at this point, the GPS antenna of terminal and base station and/
Or reflectance factor between satellite is as shown in fig. 6, the reflectance factor is terminal in the signal for receiving base station and/or satellite is sent
Afterwards, the signal reflex is to base station and/or the reflectivity of satellite, and therefore, reflectance factor is smaller, indicates the antenna port and base of terminal
Stand and/or satellite between network more match, the communication quality between terminal and base station and/or satellite is higher；Meanwhile antenna tune
Antenna radiation pattern used in humorous module selection MA antenna-matching circuit aft antennas is as shown in fig. 7, antenna radiation pattern in Fig. 7
The sectional drawing in the faces XOZ as shown in figure 8, the sectional drawing such as Fig. 9 in the faces XOY of antenna radiation pattern in Fig. 7 shows shown in；
State 2：When antenna earthing switch is off, the hardware among symmetrical breakpoint is hanging, antenna
It is matched using MB antenna-matching circuits as shown in Figure 5, at this point, between the GPS antenna and base station and/or satellite of terminal
Reflectance factor is as shown in Figure 10, which is terminal after receiving the signal that base station and/or satellite are sent, and the signal is anti-
It is incident upon the reflectivity of base station and/or satellite, therefore, reflectance factor is bigger, indicates the antenna port and base station and/or satellite of terminal
Between network more mismatch, the communication quality between terminal and base station and/or satellite is lower；Meanwhile antenna tuning module is selected
Select the faces XOZ for the antenna radiation pattern that antenna radiation pattern used in MB antenna-matching circuit aft antennas is as shown in figure 11, in Figure 11
Sectional drawing it is as shown in figure 12, shown in the sectional drawing such as Figure 13 in the faces XOY of the antenna radiation pattern in Figure 11 shows.

With signal strength detection module 1404, if the placement status of placement status detection module 1402 to terminal 1400 changes,
Trigger signal will be sent out, notifies antenna system 400 as shown in Figure 4 to carry out the switching of antenna-matching circuit, that is, controls antenna
Earthing switch enters off-state by conducting state, so that antenna-matching circuit is switched to MB antennas by MA antenna-matching circuits
With circuit, then signal strength detection module 1404 will the signal strength of detection terminal whether promoted, if signal is strong
Degree is enhanced, then is continuing with MB antenna-matching circuits；If do not promoted, it is issued by trigger signal notice antenna system again
Secondary to be switched to MA antenna-matching circuits by MB antenna-matching circuits, the placement status of wherein terminal includes but not limited to：Transverse screen is put
State is set, vertical screen placement status is placed upside down state.
Figure 15 shows the structural schematic diagram of terminal according to still another embodiment of the invention.
As shown in figure 15, show that the terminal 1500 of another embodiment of the present invention (assumes terminal in the present embodiment

Intensity detection module 1504, if business detection module 1502 arrives wireless traffic quality (such as speech quality, the data of terminal 1500
Throughput) it changes, trigger signal will be sent out, antenna system 400 as shown in Figure 4 is notified to carry out antenna-matching circuit
Switching controls antenna earthing switch and enters conducting state by off-state, so that antenna-matching circuit is by MB antenna match electricity
Road is switched to MA antenna-matching circuits, then signal strength detection module 1504 will detection terminal signal strength whether
It is promoted, if signal strength is enhanced, is continuing with MA antenna-matching circuits；If do not promoted, it is issued by triggering letter
Number notice antenna system MB antenna-matching circuits are switched to by MA antenna-matching circuits again.
