  • Frequency tunable planar internal antenna
    Patent number: 7564411
    Abstract: A frequency tunable internal antenna includes a substantially planar radiating element with a feed point and a switching element all coupled to the radiating element. The radiating element includes a plurality of slots configured to form a first branch and a second branch within the radiating element. The plurality of slots are configured relative to the feed point such that in operation the first branch acts as a first resonator having a first native electrical length and the second branch acts as a second resonator having a second native electrical length. The switching element is configurable in a first position and a second position, where in the first position the switching element connects to a portion of the first branch to decrease the electrical length of the first resonator, and in the second position the switching element connects to a portion of the second branch to decrease the electrical length of the second resonator.
