A dual-mode Wireless Local Area Network (WLAN) module installed in an electronic device (600) for wireless communication with other electronic devices includes an RF front-end unit (30), two dual-band antennas (40) coupled to the RF front-end unit, a dual-band radio frequency integrated circuit (RFIC) (20) coupled to the RF front-end unit, a dual-band base-band integrated circuit (BBIC) (10) coupled to the RFIC, and an interface unit coupled to both the BBIC and a computer (600). The RF front-end consists of transmitting and receiving paths. The RF front-end unit has antenna diversity control switching circuits (31, 33) for selecting an appropriate antenna and switching circuits (32, 34, 35, 36) for controlling ON/OFF states of transmitting/receiving paths of the RF front-end unit.
