摘要： An antenna system in a wireless communication device includes a first antenna, a second antenna, a baseband microchip, a signal sensing unit, a logical circuit, and a switch unit. The first antenna receives and transmits wireless signals; the second antenna transmits wireless signals. The baseband microchip processes the wireless signals and provides a voltage logic signal. The logical circuit logically processes the voltage logic signal and the command signal to generate different switch signals, and the switch unit is controlled by the switch signals from the logical circuit to connect to the first antenna or to the second antenna to transmit the wireless signals.
