Claim Text:
1. An electronic device comprising: a printed circuit board comprising radio frequency (RF) circuitry; an inverted-L antenna coupled to the RF circuitry, wherein the RF circuitry is operable to cause the inverted-L antenna to radiate or receive electromagnetic energy in a first frequency band, a second frequency band, and a third frequency band, wherein the first frequency band is between approximately 410 MHz and 470 MHz, and wherein the second frequency band and the third frequency band are wireless area network (WAN) frequency bands; a first impedance matching network coupled to the inverted-L antenna and a first RF feed of the RF circuitry, wherein the first impedance matching network matches an impedance of the inverted-L antenna to a first impedance of the RF circuitry to radiate or receive the electromagnetic energy in the first frequency band; a second impedance matching network coupled to the inverted-L antenna and a second RF feed of the RF circuitry, wherein the second impedance matching network matches the impedance of the inverted-L antenna to a second impedance of the RF circuitry to radiate or receive the electromagnetic energy in the second frequency band; and a third impedance matching network coupled to the inverted-L antenna and a third RF feed of the RF circuitry, wherein the third impedance matching network matches the impedance of the inverted-L antenna to a third impedance of the RF circuitry to radiate or receive the electromagnetic energy in the third frequency band.
