An antenna is a device used in a radio apparatus to transmit or receive a radio wave signal, which undergoes conversion between a high-frequency oscillation current and a radio wave during transmission and reception of the signal. The type of antenna may be divided according to the frequency of radio waves, and the current types of antennas include, for example, a bluetooth antenna, a GPS antenna, a main antenna, a diversity antenna, a WiFi antenna, and the like. Each antenna comprises a feed unit and a radiator which are electrically connected with each other, in the signal transmitting stage, a transmitting end of the feed unit inputs a high-frequency oscillation current with a certain frequency to the radiator, the radiator converts the high-frequency oscillation current into a corresponding radio wave and radiates the radio wave to the surrounding space, and in the signal receiving stage, the radiator converts the radio wave in the surrounding space into the high-frequency oscillation current and inputs the high-frequency oscillation current to a receiving end of the feed unit for identifying a radio wave signal.
In this embodiment, the circuit board, i.e. the main circuit board in the mobile terminal, has a controller 01 on the main circuit board, on one hand, the controller 01 can control the frequency of the current output by the feeding unit, so as to implement control on the signal transmitted by the corresponding antenna, and on the other hand, after the feeding unit receives the oscillating current input by the radiator, the feeding unit can feed back the current information to the controller 01, so that the controller 01 can identify the information of the external radio wave.
