Fig. 6 is a schematic structural diagram of a multi-segment tunable smart antenna 600 according to an embodiment of the invention. The multi-segment tunable smart antenna 600 is similar to the tunable smart antenna 100, but differs therefrom in that the fifth switch element SW5, the sixth switch element SW6 and the seventh switch element SW7 of the multi-segment tunable smart antenna 600 replace the first variable resistor VR1, the second variable resistor VR2 and the third variable resistor VR3, and the second control module 162 outputs the first to third switch control signals SWC1-SWC3 to the fifth switch element SW5, the sixth switch element SW6 and the seventh switch element SW7 respectively to control the switch states.
The operation mode of the tunable smart antenna 600 is similar to that of the tunable smart antenna 100, and corresponds to the low/high states of the first, second and third variable resistors VR1, VR2 and VR3 with the on/off states of the fifth, sixth and seventh switch devices SW5, SW6 and SW7, wherein the on states of the fifth, sixth and seventh switch devices SW5, SW6 and SW7 correspond to the low states of the first, second and third variable resistors VR1, VR2 and VR3, and the off states of the fifth, sixth and seventh switch devices SW5, SW6 and SW7 correspond to the high states of the first, second and third variable resistors VR1, VR2 and VR 3.
For example, when the tunable smart antenna 100 is a single-loop antenna, the first variable resistance value is a low resistance value, the second variable resistance value is a high resistance value, and the third variable resistance value is a high resistance value. Thus, for the tunable smart antenna 600, the fifth switch element SW5 is turned on, the sixth switch element SW6 is turned off, and the seventh switch element SW7 is turned off, so as to electrically connect the second radiator 120 with the ground 140, electrically disconnect the first connector 151 from the ground 140, and electrically disconnect the third radiator 130 from the ground 140. By controlling the switching states of the fifth switch element SW5, the sixth switch element SW6 and the seventh switch element SW7, the tunable smart antenna 600 can be a single-loop antenna.
For another example, when the tunable smart antenna 100 is a planar inverted-F antenna, the first variable resistance value is a high resistance value, the second variable resistance value is a low resistance value, and the third variable resistance value is a high resistance value. Thus, for the tunable smart antenna 600, the fifth switch element SW5 is turned off, the sixth switch element SW6 is turned on, and the seventh switch element SW7 is turned off, so as to electrically disconnect the second radiator 120 from the ground 140, the first connector 151 from the ground 140, and the third radiator 130 from the ground 140. By controlling the switching states of the fifth switch element SW5, the sixth switch element SW6 and the seventh switch element SW7, the tunable smart antenna 600 can be a planar inverted F antenna.
For another example, when the tunable smart antenna 100 is a dual-loop antenna, the first variable resistance value is a high resistance value, the second variable resistance value is a high resistance value, and the third variable resistance value is a low resistance value. Thus, for the tunable smart antenna 600, the fifth switch element SW5 is turned off, the sixth switch element SW6 is turned off, and the seventh switch element SW7 is turned on, so as to electrically disconnect the second radiator 120 from the ground 140, electrically disconnect the first connector 151 from the ground 140, and electrically connect the third radiator 130 to the ground 140. By controlling the switching states of the fifth switch element SW5, the sixth switch element SW6 and the seventh switch element SW7, the tunable smart antenna 600 can be a dual-cycle antenna.
