1. An electronic device, comprising:
a housing; a wireless transceiver disposed within the housing; a main antenna coupled to the transceiver and configured to enable the transceiver to operate in at least four wireless frequency bands; and a diversity antenna coupled to the transceiver, the diversity antenna configured to receive signals in at least the four wireless frequency bands and configured as an inverted F-antenna, the diversity antenna comprising:
a first portion having a first end and a second end, the first portion configured to enable the transceiver to receive a signal in a first low-band frequency of the four frequency bands;a second portion connected to the first end of the first portion, the second portion configured to enable the transceiver to receive signals in first and second high-band frequencies of the four frequency bands;a third portion RF coupled to the first portion when the third portion is connected to ground, the third portion configured to tune the first portion such that the transceiver receives a signal in a second low-band frequency of the four frequency bands; anda switch connected between the third portion and the ground, wherein when the switch is open, the first portion enables the transceiver to receive the signal in the first low-band frequency, and wherein 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. |
