Patent ID: 7898485

Claim:
A wireless handheld electronic device comprising: storage that stores data; processing circuitry coupled to the storage that generates data for wireless transmission and that processes wirelessly received data; and wireless communications circuitry, wherein the wireless communications circuitry comprises: transceiver circuitry; first and second antennas; and first and second transmission lines, wherein the first transmission line has a ground conductor and has a signal conductor and conveys radio-frequency signals for the first antenna between the transceiver circuitry and the first antenna, wherein the second transmission line has a ground conductor and has a signal conductor and conveys radio-frequency signals for the second antenna between the transceiver circuitry and the second antenna, wherein the first antenna operates in a first frequency range and a second frequency range, wherein the second antenna operates in a third frequency range that is different than the first and second frequency ranges, wherein the first antenna comprises a planar ground element with a dielectric-filled slot and a planar resonating element located above the slot, and wherein the planar resonating element comprises an antenna isolation element that resonates in the third frequency range and isolates the first antenna and the second antenna in the third frequency range.
