A wireless communication function of the portable electronic device 200 may be implemented by using the antenna 1, the antenna 2, the mobile communications module 215, the wireless communications module 217, the modem processor, the baseband processor, and the like.
The antenna 1 and the antenna 2 are configured to: transmit and receive an electromagnetic wave signal. Each antenna in the portable electronic device 200 may be configured to cover one or more communication frequency bands. Different antennas may be further multiplexed, to improve antenna utilization. For example, the antenna 1 may be multiplexed as a diversity antenna in a wireless local area network. In some other embodiments, the antenna may be used in combination with a tuning switch.
