Abstract
An electronic device includes a main antenna and a diversity antenna. The diversity antenna includes a first portion configured to enable a transceiver to receive a signal in a first low-band frequency of four frequency bands. A second portion enables the transceiver to receive a signal in first and second high-band frequencies. A third portion is RF coupled to the first portion when the third portion is connected to ground. The third portion tunes the first portion such that the transceiver receives a signal in a second low-band frequency. A switch is connected between the third portion and the ground. When the switch is open, the first portion enables the transceiver to receive the signal in the first low-band frequency. When the switch is closed, the third portion tunes the first portion to enable the transceiver to receive the signal in the second low-band frequency.
