  • Electronically tunable planar antenna and method of tuning the same
    Patent number: 6933893
    Abstract: An electronically tunable planar antenna 12, a wireless communication device 10, and a method of tuning an antenna 12 in which a high band element 28 and a low band element 26 each have a resonant center frequency. At any given time, the antenna 12 has two center resonant frequencies and thus allows the device to operate at two frequencies simultaneously. In addition, tuning circuits 38, 36 are connected to the low band element 26 and the high band element 28, respectively. The tuning circuits 36, 38 electronically change the resonant center frequency of the corresponding element 26, 28. Accordingly, in the device 10 the method, and the antenna one or both of the center frequencies can be changed to permit operation at more than two frequencies.
