Abstract
A mobile terminal switching antenna and a switching method thereof include an antenna, RF module, baseband chip, voltage dividing module, noise barrier module, DC blocking module, unidirectional conduction module, and antenna matching module. The baseband chip is coupled to the antenna via the RF module. The baseband chip is coupled to the antenna sequentially via the voltage dividing module, noise barrier module, and DC blocking module. The baseband chip is grounded sequentially via the voltage dividing module, noise barrier module, unidirectional conduction module, and antenna matching module. By the baseband chip not emitting or emitting the control signal to the antenna, the switching of the operative states of the antenna is thus realized, and the range of the frequency bands which can be received by the antenna is changed correspondingly, thereby greatly enhancing the receiving and transmitting performances and providing convenience to users.
